Subsection 200-2.2, Crushed Aggregate Base, or Subsection 200-2.4, For field compaction verification, report the day’s theoretical maximum density (Rice value) using the average of two tests from one split of a single sample pulled at a random time during the shift the verification core is pulled. Section 39, “Asphalt Concrete,” of the Standard Specifications provides material and construction requirements for hot mix asphalt (HMA) including Type A, rubberized hot mix asphalt-gap graded (RHMA-G), open-graded friction course (OGFC), minor HMA, and hot mix asphalt with warm mix asphalt (WMA) additive technology. The Aggregate Acceptance Unit ensures the quality of aggregates in Florida’s transportation system by approving and monitoring aggregate sources. Table 1 also includes the Designated Large Sieve (DLS) sizes for each mix. (Reclaimed asphalt pavement does not need to be sampled for sand equivalent.) acceptance in accordance with SSPWC Section 4-1.4.

Another way to look at it is this: In a 6000 lb. Make sure the contractor makes a 2-inch deep saw cut along limits where asphalt is designated to be removed. Inform the contractor in writing that the material represented by the two out-of- specification acceptance tests is noncompliant, and include a statement that the noncompliant material is rejected and must be removed or remedied in accordance with Section 5-1.30, “Noncompliant and Unauthorized Work,” of the. Documentation should include high-resolution digital photographs or videos. B. The contractor must sample in accordance with California Test 125, “Method of Test for Sampling Highway Materials and Products Used in the Roadway Pavement Structure Sections,” and give the resident engineer three of the four split samples. When a vibratory roller is specified for compaction, the speed of the vibratory roller in miles per hour does not exceed the vibrations per minute divided by 1,000. The contractor to compare quality control test results against Caltrans’ acceptance test results on split sample material. Use the MultiCool program as a guide for determining the length of time available for achieving compaction, based on layer thickness, HMA temperature, existing pavement temperature, and atmospheric temperature. additive. shall be crushed particles in lieu of the requirements of SSPWC, thickness of layers, then separate mix designs shall be performed When the standard process is specified, discuss the requirement to pull density cores from random locations determined by the engineer and that cores must be pulled in the engineer’s presence and provided to the engineer at least once every 5 business days. Obtain aggregate samples from stockpiles or aggregate belts before lime treatment, in accordance with California Test 125. This specification covers the requirements for the materials, equipment, and methods to be followed for proportioning and mixing hot mix asphalt, including recycled mixes and mixes for miscellaneous work. same. If any single quality characteristic, except smoothness, has two consecutive acceptance or quality control tests out of compliance with the specifications, verify that before resuming production and placement of HMA on the project, the contractor: The contractor must comply with the method process in Section 39-2.01C(2)(c), “Method Compaction Equipment,” and in Section 39-2.01C(15)(b), “Method Compaction,” of the Standard Specifications if: When the total paved thickness is at least 0.15 foot: Except for areas that must be tested for smoothness using a 12-foot straightedge, make sure the contractor tests all finish surfaces of HMA and the finish surface the open-graded friction course (OGFC) is being placed on, with an inertial profiler. Test aggregate at the frequency shown in Table 6-1.13, “Materials Acceptance Sampling and Testing Requirements,” of this manual. A. Regardless of the type of antistrip treatment chosen by the contractor, the HMA must meet the requirements of AASHTO T 283, “Standard Method of Test for Resistance of Compacted Asphalt Mixtures to Moisture-Induced Damage,” and AASHTO T 324, “Standard Method of Test for Hamburg Wheel-Track Testing of Compacted Asphalt Mixtures.”. yd. Marshall stability*, The contractor performs quality control testing for asphalt rubber binder, gradation, and fabric content of crumb rubber modifier; aggregate and reclaimed asphalt pavement moisture; and reclaimed asphalt pavement gradation and binder contents. If any test results exceed the specified limits, the testing laboratory will immediately notify the resident engineer. If cores show significant differences in material type or The analysis is performed each day and upon completion of each lot using a Caltrans-furnished spreadsheet titled SPFPay. have been spattered or defaced as a result of the paving operation. Hot mix asphalt aggregate lime treatment—slurry method, Hot mix asphalt aggregate lime treatment—dry lime method, Verify with the district weights and measures coordinator that the proposed lime treatment plant is Caltrans-qualified in accordance with the. If reclaimed asphalt pavement is used, determine aggregate gradation in accordance with California Test 384 “Method of Test for Combining Gradations for Hot Mix Asphalt (HMA) Using Reclaimed Asphalt Pavement (RAP) and/or Reclaimed Asphalt Shingles (RAS).” California Test 384 is available at: Notifies the contractor of aggregate gradation and sand equivalent test results, and confirms that any required plant adjustment has been made to correct for out-of-specification aggregate gradation. A new lot starts when twenty sublots are complete, a new job-mix formula is used, or when production stops for more than 30 days. Confirm that the accepted job mix formula has not changed. The contractor samples in accordance with California Test 125, “Method of Test for Sampling Highway Materials and Products Used in the Roadway Pavement Structure Sections.”. Pay factor quality characteristic tests for each lot are statistically evaluated to determine the PWL after completing each sublot. The most efficient pugmill mixing occurs when the material level remains at the top of the paddles along the length of the mixer. Contractors can choose to begin production during this investigation but proceed at their own risk. Test aggregate at the frequency shown in Table 6-1.13 of this manual. The engineer allows the contractor to continue production of a lot only after the contractor identifies which sublots will be removed and rejected from the lot. If the contract includes prepaving grinding: Emphasize that prepaving grinding work is only applicable to existing asphalt concrete surfaces that have not been cold planed or replaced. Consult with the district materials engineer and either the Division of Maintenance Office of Asphalt Pavements, the district’s construction field coordinator, or both, about acceptance of the contractor’s proposal. The job mix formula requirements are the same for the standard and SPF specification processes.

If the contractor’s quality control test for a single non-pay factor quality characteristic falls out of specification two consecutive times, or any non-pay factor quality characteristic fails 3 times in a single day, the contractor must stop production, notify the engineer and demonstrate compliance before continuing production. The B. The CRM must also include 25 percent, plus or minus 2 percent, high natural rubber content scrap rubber by mass of the CRM that may come from scrap tires or other sources. Prohibit the contractor from applying fog seal coat to the traveled way.

Products and Services / Standards & Publications / Standards Products. Record the type of mix, the HMA producer, the producer’s mix identification number, and the production tonnage that this sample represents. The contractor must comply with the specifications for placement, such as temperature and roller requirements. Review the contractor’s quality control test results to verify that testing meets the specifications for Caltrans acceptance. Where smoothness is to be measured with an inertial profiler, the contractor must measure smoothness with an inertial profiler that meets the requirements of Section 36-3, “Pavement Smoothness,” of the Standard Specifications. It is good practice to test aggregate samples for moisture content in accordance with AASHTO T 255, “Total Evaporable Moisture Content of Aggregate by Drying,” or AASHTO T 329, “Standard Method of Test for Moisture Content of Asphalt Mixtures by Oven Method,” because moisture influences proportioning.
