MDOT is committed to ensuring that projects, programs and services are performed without discrimination, under Title VI. Communication is one of the keys to a safe work environment. Refer to Figure 502-13 for some typical mat appearances. FY 2025 Local Bridge Program Call For Applications - Due April 2022 No matter what type of plant is being used, several key items should be monitored. Some pavements may be disintegrated so badly that the fragments may have to be removed. The initial acceptance form, contained in the contract documents, is to be filled out when the warrantied work has been completed and accepted. The incline of a paving surface in the direction of travel, expressed by stating the rise or fall as a percentage of horizontal distance. To convert the yield to mat thickness, the following will be helpful: 110 pounds/square yard = 1 inch of thickness. The office is responsible for media relations, social media, and website development. Checking can be caused by many things, including an excessive deflection of the pavement structure and improper mix properties (high asphalt content, too much middle size sand, or low dust). This is helpful at lane tapers, crown corrections, or in areas of wedging. The tractor unit is powered by its own engine and provides the power to move the paver forward, either on rubber tires, or crawler tracks. All existing pavements, including newly-constructed HMA surfaces, which are to be surfaced with HMA, will receive a bond coat application. This is true for both the Project Engineer and his staff and for the Contractors general superintendent, plant and paving superintendents and all foremen. Intermittent operation of the slat conveyors and auger system could cause both auger shadows and ripples in the mat behind the screed. As of January 1, 2022 the Personal Net Worth Cap applied to the Minority Business Enterprise (MBE) program will increase from to $1,788,677 to $1,847,024. 310 0 obj <> endobj 312 0 obj <>>>/Contents 313 0 R/StructParents 0/Tabs/S/CropBox[ 0 0 612 792]/Rotate 0>> endobj 313 0 obj <>stream The hitch is controlled by the paver operator. Therefore, the first sample should be taken 1985 feet from the beginning of the pavement and 6.3 feet from the designated (right or left) edge of the pavement. The slope control operates through a slope sensor that is located on a cross beam between the two side arms on the screed. Public Notice of Grand Region Bridge Council Meeting for October 10, 2022 In this instance, the two numbers chosen were: 0.376 and 0.529, for length and transverse offset. Trucks should stop short of the paver and be picked up by the paver. A slight change in direction, or curl, is beneficial at each reversal spot to further reduce the tendency of the mix to shove under the compactor and to eliminate the possibility of a bump at the point where the roller reversal occurs. x 0 ;r0Do9r\( [v9pWnY?xF Nonuniform mixing shows up as spots of lean, brown, and dull appearing material within areas of rich and shiny appearance. The aggregate base must provide a firm foundation before paving commences. Communication cannot stop once the pre-production meeting is concluded. Screed plates first wear out about four to six inches from the trailing edge. Our goal is to keep Michigan's motorists safe, informed, and mobile. The method for determining the binder grade in HMA mixtures incorporating RAP and/or RAS is divided into three categories designated Tier 1, Tier 2 and Tier 3. Qualification of the material sampling technicians should be a pre-production meeting agenda item.

If the wedging course is 3 inches or less, the inspector should string line the area to be wedged to determine the limits of wedging. There are four basic types of grade references that can be employed to maintain the elevation of the screed pull point: the erected string line, the mobile mat reference, 30 foot floating ski, and the joint matching shoe. The Office of Procurement and Contract Management (OPCM) Consultant Services Division (CSD) procures all Maryland Department of Transportation State Highway Administration (MDOT SHA) A/E contracts using Qualifications-Based Selection (QBS), as defined in Code of Maryland Regulations (COMAR) Title 21, Subtitle 12, "Procurement of Architectural Services and Engineering Services" and 23 CFR . This type rollers compactive effort is a function of the wheel load, the tire pressure, the tire design and the depth of penetration of the tires into the mix. The amount bid for HMA may be adjusted. The bond coat material shall be applied ahead of the paving operation for a distance of at least 1500 feet, depending upon traffic conditions, as determined by the Engineer. Refer to Figure 502-15 for details of joint construction. The next truck should then be backed toward the paver, stopping short of the paver. This will happen on windy days and when the mat thickness is thin, normally the wearing course. The breakdown roller should be as close to the paver as possible. The slat conveyor on one side operates independently from the movement of the other side. Item 340 is generally not recommended for projects with more than 5,000 tons of HMA. These devices are used to carry the mixture from the hopper through the paver tunnel to the back of the paver and the spreading augers. These asphalt cements may also contain anti-strip agents. Once the Contractor has finished the rolling operation, the inspector will identify the locations where the density cores will be taken; these locations are randomly selected both longitudinally and transversely. Changes occur because of material supply, equipment breakdown, Contractor and Subcontractor schedules and weather conditions. Warranties are a tool to assure quality, but they are not a replacement for proper inspection, quantity measurement, proper payments, or proper contract administration. The existing surface texture will determine the rate of application up to the maximum rate of 0.10 gallons/square yards. One of the most important considerations in making a longitudinal joint is keeping the paver on a straight line of travel. After coring is completed, the inspector should check the layer thickness for conformance to the standard specifications. These are notes from meetings between MDOT SHA and industry about improving the quality of materials used on State highways. 311 0 obj <>stream The augers are used to distribute the mixture across the total width of the screed. If temperatures warrant, the sides and bottom of the truck bed should be insulated. Determine the length of one pavement representing a sublot of material, the width of the pavement and the number of samples, (n), needed for each sublot. Did you know that millions of people visit the Great Lakes State every year? If it falls at the free edge of the pavement, the core location should be moved 2 inches in from the edge. 316 0 obj <<1cc850f8a7a5b5157c73556bf669a59d>]>>stream Dividing the tonnage placed, by the area covered, will give the yield. Experience has shown that these sections generally settle after a short period of time. Plan Approval. The outcome of each conversation must be recorded; who told whom to do what, and what was the reply? If the millings have aggregates larger than what is required for the mix design, it should be processed (crushed and/or screened) prior to stockpiling*. After a short mixing process, the asphalt cement is added and the entire mixture is mixed for 30 to 45 seconds. A rule of thumb is that the proper level of air voids should be obtained before the mixture cools to a temperature of 176F. The aggregate base course must meet all the requirements for moisture content, density and smoothness. Each of these factors has an effect on the level of density achieved under the compactive effort applied to the mat. It is the MDOT inspectors responsibility to ensure that the Contractor is providing a specification product. Rocking slabs must be stabilized. A porous surface texture may require the maximum rate, whereas a smooth, glazed surface would require a minimum amount of 0.05 gallons/square yards. Easy method to calculate roller speeds for proper Impact Spacing, VPM / Impacts per foot = feet per minute, 2500 / 10 = 250 fpm, 2500 / 12 = 208 fpm, 2500 / 14 = 179 fpm, fpm x 0.01136 = fpm / 88 = mph, 208 fpm x 0.01136 = 208 fpm / 88 = 2.36 mph. This article returns the responsibility for these tasks to MDOT for all concrete paving projects, including those that contain special provisions 03SP602A and/or 03SP602E. Interim and Final Inspection forms must be filled out even if there are no deficiencies and filed in ProjectWise. `qr`@UtT! u#$$mB3B2(&qiB[g%R(ck7H,D"-Vg#Y Long delays, caused by the lack of trucks, or filling the roller with water, allow the roller to indent the new mat. Are the mats or wheel scrapers in good operating condition? Clear responsibility for maintenance of all traffic control devices, such as signs, pavement markings and flagging, should also be defined. Distributor Checklist - Manufacturer and Distributor Number -______________________________. Cold-milling machines may be used to do the work involved in the pay item of removing HMA surface by the square foot (square meter). Plan the width of application to ensure having bond coat under the matching longitudinal joint. Saturated areas must be allowed to dry prior to placing mixture. If it is below the specification limit, 250F, it should be discarded. Pressure distributors are used to apply a uniform application of the asphalt emulsions, normally referred to as the tack or bond coat. Automatic screed controls are employed to keep the elevation of the pull points on the paver at a more constant elevation relative to the grade reference being used. The good looking surface texture can lull the operator into a false sense of security. Safety Project Submittal (Form 1627), 2024 Streamlined Systemic HSIP Selection List At MDOT, we want to ensure your voice is not only heard, but makes a difference in moving Michigan forward. Care should be taken to neatly construct the joint at a right angle to the centerline of the roadway. It spans from northern Canada to Mexico near the equator. FY 2013 Before and After Crash Study The distance between the end of the auger extension and the end gate should be about 12 inches. An end gate is attached to the end of the screed to restrict the outward movement of the mix around the end of the screed. Resources for local governments regarding grant & economic development opportunities, project coordination, and state and federal requirements. x\YoF~A4 M!"Gcy-3_}TA(z #*v}Ow>~_c~y}On}]mvy}Rc*UQ]n/?]v./8:~o?Q`Sv;WE]f_MAuOF}@,c?uQUYcmEEPuB',~WMQsE$XF-,V-g6mMa%[+ndv6>%T&G/fQx&[0{Rm z5WB3^sha!QBk`LB#D1V'iuZtDW}} . Several different organizations publish short, concise safety presentations that can be completed in two to three minutes. Material Quality. This checklist may be placed in the project files. MDOTs Local Agency Program assists local agencies with preserving state and federal aid in a fair and consistent manner and serves as an information resource. Paver speed for various production and application rates can be calculated using the following equations or selected from Figure 502-5. It can be configured for automatic grade and slope, or dual grade control, as shown in Figure 502-8. The Veteran Internship Program assists honorably discharged veterans of the United States Armed Forces as they transition into the civilian workforce. If the wedging is greater than 3 inches, two courses of HMA mixture may be required. The first is the frequency of vibration and the second is the amplitude of the compactive effort. Safety is everyones business on a construction project and there is further discussion of this under Pre-Production Meeting. Unsere Bestenliste Jan/2023 Detaillierter Produktratgeber TOP Grey goos vodka Aktuelle Angebote Vergleichssieger Direkt weiterlesen. If aggregates larger than what is required for mix design still exist after processing, the contractor must demonstrate that additional screens are installed on the RAP feed system to ensure that the RAP being introduced into the HMA mixture contains no aggregate larger than the top size aggregate allowed in the mix design. When a feathered joint is required, it should be constructed as follows. Certifications are good for one construction season only. It is very important to know what special provisions are contained in the proposal. It is important that the augers carry a consistent amount of mix across the front of the screed so that the pressure on the screed is kept as constant as possible. Can VPM be locked in on vibratory rollers? The front of the hopper must be constructed in a way to minimize the spillage of mix from the hopper. The weigh bridges on the cold feed and RAP charging conveyors must be calibrated. Selection of appropriate pavement marking materials (paint, thermoplastic . % Cleaning of the roadway surface may be a pay item. The Bureau of Bridges and Structures is responsible for statewide policy, procedure development, and execution to ensure all bridges and structures are designed, constructed, maintained, and operated to ensure safety. Safety talks are a very good way to start each day for both the Contractor and MDOT personnel. If a good bond is not formed between the existing surface and the new overlay, a slippage, or sliding-type, failure can easily occur. Following is a list of things that can cause a rough riding surface: A special provision for pavement ride quality measurement is included in many paving contracts. Of sufficient weight and strength to resist tearing. These guidelines will be incorporated into the next version of the HMA Production Manual. The tire pressure used depends, in part, upon the number of plies used in the tires. It is MDOTs responsibility to conduct quality assurance and verification sampling and testing to ensure conformity of the mix to 20SP501(R) Superpave Hot Mix Asphalt Percent Within Limits (PWL) or 20SP501(S) Superpave Hot Mix Asphalt Percent Within Limits (PWL) For Capital Preventive Maintenance (CPM) Mill & Resurface Projects and CPM One Course Overlay Projects.This testing is done at the field laboratory provided by the Contractor located at the asphalt plant or at an MDOT Region Lab. Transportation System Performance allows MDOT's regions and engineers to expand their knowledge on how Michigan freeways are operating over time and how they compare to each other. Asphalt paving projects, like many construction projects, are not always built as originally scheduled. See Figure 502-3. If it exceeds optimum placement temperature, but does not exceed the specification limit, the truckload is usually not discarded, but immediate steps should be taken to correct the condition. Copies of the letters sent should also be filed in the ProjectWise folder for future reference. The length of temporary taper shall be 5 feet for each inch of mat thickness. Things that can cause a nonuniform application are, improper temperature, improper pump speed, sprayer bar height improperly set, spray nozzles clogged, or the nozzle overlap pattern is improperly adjusted. To reach the required density, the quickest initial compaction should occur directly behind the lay down machine. The aggregate base must be rolled after final trimming in order to pack down any loose gravel and minor dips caused by the trimmer. These adjustments should be completed within the first two loads placed. Does the distributor have a capacity of at least 800gallons (3,000 liters)? See Figure 502-6. Compaction of the taper section will be required as near to final density as possible. MaineDOT Best Management Practices for Erosion & Sedimentation Control ( 3/27/2008 update) MaineDOT Construction Manual MaineDOT Elation System Users Manual ( 1/1/2021 update) MaineDOT Maintenance Fast-dry Water-Based Traffic Paint ( 3/23/2016 update) Standard Details Book & Updates ( 7/8/2022 update) To minimize mat problems, the paver operator should dump the wings as little as possible. Adequate compaction of the mix increases the pavement life, decreases permanent deformation, reduces oxidation or aging of the asphalt binder, decreases moisture damage, increases strength and stability and decreases low temperature cracking. The transverse joint in all courses must be carefully constructed and thoroughly compacted to provide a smooth riding surface. The results of all daily and periodic tests conducted at the asphalt plant must be recorded on the appropriate MDOT form. All traffic must be kept off of the bond coat until it is cured. This check is done by roughly measuring the area covered by one truckload; the tonnage placed is known from the load ticket. When the paving operation is discontinued, a transverse joint must be constructed. The last meter of the HMA material should be raked and all the large stones removed, leaving the fine material. <> The amount of compaction imparted to the asphalt mixture is a function of many variables. The substitution of another HMA mixture type other than the recommended mixture is acceptable if it has demonstrated to perform under similar traffic conditions. Most drum mixer plants heat the aggregate, add the asphalt cement and recycled asphalt pavement (RAP), if used, and mix all the ingredients in the same drum. MDOT's Highway Programs focus on the development and management of the department's roadsides, environmental efforts and policies, and federal-aid highway information. Document the extraction of the cores from the locations marked (random numbers, date, time, etc.). The dump bed should not hit the paver when dumped. This arrangement permits an average to be taken from the grade surface and another to be taken from the freshly laid mat. icPUBJ FP rM4"d_`Sx".HCaM;)v}khmqj*KDRu`JK*l*fiEpg[`+H9g@ Ct)L;9BnLjvJdQP7BHD#},i-7D4lPNy`B_]Z)Hg BWPl!3I8"#wQjBANtNV #P9!#)C6.q]BX9#mCw This description is referenced in item number 112 of the Michigan Structure Inventory and Appraisal Coding Guide. Rough, uneven surfaces should be leveled. Alignment of the front edge of the extension is typically controlled independently of the alignment of the rear edge of the extension. The tractor unit provides the motive power to the paver and to transfer the mixture from the receiving hopper on the front of the paver to the spreading augers at the back of the paver. On structures in the curb line out of the traveled roadway, the top of the cover should be 3/8 inch (8 mm) below the wearing surface after final compaction is completed. It is important for the screed extension to be attached securely to the main screed. Drum mixers come in many different types, such as parallel flow, counter flow, double barrel, drum-within-a-drum and drums with separate mixing chambers (Figure 501-4). Compaction must be achieved while the stiffness of the mix is low enough to allow for reorientation of the aggregate particles under the action of the rollers. 2023 Streamlined Systemic HSIP Selection List Cutoff shoes can be used, if necessary, to reduce the width of mixture being placed to a width that is less than the basic main screed width. If an unsafe work practice is noticed, corrective action should be taken immediately, even if the paving operation has to be shut down until the unsafe practice is corrected. The faster a roller passes over a point on the asphalt surface, the less time the weight of the roller has to work on that point; this means that less compactive effort is applied to the mixture. Once the truck bed has been emptied of mix, the truck hitch is withdrawn and the truck is able to pull away from the paver. 111 0 obj <>stream The aggregates are then proportioned by weight into the mixer, also called the pug mill. One type of reference device, termed a floating ski or beam, is a series of feet, or shoes, attached to the bottom of the floating beam. <>/Metadata 445 0 R/ViewerPreferences 446 0 R>> It is necessary for the screed to be the same temperature as the mixture being placed in order to assure that the mix does not stick to the screed plate and tear the mat, causing a rough texture to the surface. The screed of the second paver must be set at the same level as the screed of the first paver; this will prevent the screed of the second paver from dragging on the mix placed by the first paver. The names and titles of any people involved in the discussion should be written down, as well as the topics discussed. Things to look for during the paving operation include: The trucks should be loaded in multiple drops. If a conversation is held with other project personnel concerning project activity, the date and location of the conversation should be recorded. . **If in line crushing and/or screening is being used to ensure that the RAP being introduced into the HMA mixture contains no aggregate larger than the top size aggregate allowed in the mix design a RAP scalper screen may not be required. A list of MDOT personnel who will be assigned to the project should be provided to the Contractor. Figure 502-11 illustrates the wedging process. The screed should be raised and the bottom surface checked for smoothness, twisting, and excessive wear. 2P3G(30120&gp9@. The typical equipment used: Used for cleaning the old surface to be paved. The screed extensions should be level with the main screed. 1TN7ln^cFgI,ubJZ&8,qz&Q. ?^7djE-/. This principle allows the paver screed to average out changes in grade that are experienced by the tractor wheelbase. One make of paver, however, is equipped with a power extendable screed that places the extendable portion of the screed in front of the main screed. The applied amplitude is determined by the location of the eccentric weights that are located on the shaft.
