3.1. TRAIL. Provide the equipment recommended by the producer.

3.2. Underseal Membrane. Provide in accordance with Special Specification 3005, “Spray Applied Underseal Membrane.”

4. CONSTRUCTION

4.1. Preparation. Clean the surface before placing the bonding course. Apply bonding course uniformly at the approved rate, unless otherwise directed. The Engineer will set the rate between 0.04 – 0.14 gal. of residual asphalt per square yard of surface area. The Engineer may adjust the application rate, taking into

2 - 3 06-24 Statewide consideration the existing pavement surface conditions. Prevent splattering of the bonding course when placed adjacent to curb, gutter, and structures, Apply a thin, uniform tack coat to all miscellaneous contact surfaces of curbs, structures, and joints. Prevent splattering of the tack coat when placed adjacent to curb, gutter, and structures.

4.2. TRAIL. Perform the following construction methods when applying a TRAIL for a bonding course:

4.2.2. Test Strips. When required by the Engineer, perform a test strip of TRAIL at a location on or near the project as directed. Allow the strip to cure for a maximum of 30 min. Drive over the test strip with equipment used during laid-down construction to simulate the effect of paving equipment. There should be no evidence of tracking or picking up of the TRAIL material on the wheels of the equipment.

4.2.3. Placement. Uniformly apply the TRAIL material to all areas where mix will be placed, including joints, at the rate shown on the plans or as directed, within 15°F of the approved temperature, and not above the maximum allowable temperature. Unless otherwise directed, uniformly apply the TRAIL material at a minimum rate specified on the plans. The Engineer will set the application rate between 0.06 – 0.14 gal. per square yard for emulsion TRAIL and the application rate between 0.08 – 0.12 gal. per square yard for hot-applied TRAIL.

4.3. Underseal Membrane. Place in accordance with Special Specification 3005, “Spray Applied Underseal Membrane.”

4.3.2. Placement. Do not allow any loose mixture onto the prepared surface before application of the membrane.

Unless otherwise directed, uniformly apply the membrane to all areas where mix will be placed, including joints, at the rate shown on the plans. Unless otherwise directed, uniformly apply the membrane at the minimum rate specified on the plans. The Engineer may adjust the application rate, taking into consideration the existing pavement surface conditions. The Engineer will set the application rate between 0.10 – 0.22 gal.

per square yard for underseal membrane.

4.4. Quality Control. Stop application if it is not uniform due to streaking, ridging, pooling, or flowing off the roadway surface. Verify equipment condition, operating procedures, application temperature, and material properties. Determine and correct the cause of non-uniform application.

The Engineer may perform independent tests to confirm contractor compliance and may require testing differences or failing results to be resolved before resuming production.

The Engineer may stop the application and require construction of test strips at the Contractor’s expense if any of the following occurs:

non-uniformity of application continues after corrective action;

evidence of tracking or picking up of the TRAIL;

in three consecutive shots, application rate differs by more than 0.02 gal. per square yard from the rate directed; or any shot differs by more than 0.04 gal. per square yard from the rate directed.

The Engineer will approve the test strip location. The Engineer may require additional test strips until surface treatment application meets specification requirements.

5. MEASUREMENT

5.1. Volume. Asphalt material, including all components, will be measured at the applied temperature by strapping the tank before and after road application. The distributor calibrated strap stick will be used for measuring the asphalt level in the distributor asphalt tank. The certified tank chart will be used to determine the beginning gallons and the final gallons in the distributor tank. The quantity to be measured for payment will be the difference between the beginning gallons and the final gallons.

The Engineer will verify that the specification requirements are met when the Contractor makes a source or formulation change, and may require a new laboratory mixture design, trial batch, or both. Any subsequent mention of testing in this Specification will not be required by either the Engineer or Contractor unless the Engineer determines a need for the testing.

2.1. Aggregate. Furnish aggregates from sources in accordance with the requirements shown in Table 1 and this Section. Aggregate requirements in this Section, including those shown in Table 1, may be modified or eliminated when shown on the plans. Additional aggregate requirements may be specified when shown on the plans. Provide aggregate stockpiles that meet the definitions in this Section for coarse, intermediate, or fine aggregate. Aggregate from reclaimed asphalt pavement (RAP) is not required to meet Table 1 requirements unless otherwise shown on the plans. Supply aggregates that meet the definitions in Tex-100-E for crushed gravel or crushed stone. The Engineer will designate the plant or the quarry as the sampling location. Provide samples from materials produced for the project. The Engineer will establish the surface aggregate classification (SAC) and perform Los Angeles abrasion, magnesium sulfate soundness, and Micro-Deval tests. Perform all other aggregate quality tests listed in Table 1. Document all test results on the mixture design report. The Engineer may perform tests on independent or split samples to verify Contractor test results. Stockpile aggregates for each source and type separately. Determine aggregate gradations for mixture design and production testing based on the washed sieve analysis given in Tex-200-F, Part II.

2.1.1. Coarse Aggregate. Coarse aggregate stockpiles must have no more than 20% material passing the No. 8 sieve. Aggregates from sources listed in the Department’s Bituminous Rated Source Quality Catalog (BRSQC) are preapproved for use. Use only the rated values for hot-mix listed in the BRSQC. Rated values for surface treatment (ST) do not apply to coarse aggregate sources used in hot-mix asphalt.

For sources not listed on the Department’s BRSQC:

build an individual stockpile for each material;

request the Department test the stockpile for specification compliance;

allow 30 calendar days for the Engineer to sample, test, and report results;

use only when tested and approved; and once approved, do not add material to the stockpile unless otherwise allowed.
