2.2. Type I LRA and Type II LRA Mixtures. Type I LRA mixture consists entirely of native LRA aggregate, flux material, water, and additives. Type II LRA mixture consists of a blend of native LRA aggregate, virgin aggregates, fluxing material, additives, and water.
Provide LRA mixtures of the type, grade, and SAC shown on the plans or purchase order and in accordance with the following requirements.
2.3. Aggregate. Furnish aggregates from sources that conform to the requirements shown in Table 1A or Table 1B and as specified in this Section, unless otherwise shown on the plans. Provide aggregate stockpiles that meet the definition in this Section for either a coarse aggregate or fine aggregate. Supply mechanically crushed gravel or stone aggregates that meet the definitions in Tex-100-E. Materials and Tests Division (MTD) will designate the plant or the quarry as the sampling location. Samples must be from materials produced for the project. The Engineer will establish the SAC and MTD will perform Los Angeles abrasion, magnesium sulfate soundness, and Micro-Deval tests. Perform all other aggregate quality tests listed in Table 1A or Table 1B and document all test results. MTD may run tests on independent or split samples to verify Contractor test results. Stockpile aggregates for each source and type separately.
2.3.1. Coarse Aggregate. Coarse aggregate stockpiles must have no more than 20% material passing the No. 10 sieve. Provide aggregates from sources listed in the Department’s Bituminous Rated Source Quality Catalog (BRSQC). Provide non-listed sources only when tested by MTD and approved before use. Allow 30 calendar days for MTD to sample, test, and report results for non-listed sources.
Provide coarse aggregate with a minimum SAC as shown on the plans. SAC requirements apply only to aggregates used on the surface of travel lanes, unless otherwise shown on the plans. The SAC for sources on the Department’s Aggregate Quality Monitoring Program (AQMP) is listed in the BRSQC.
When a Type II LRA mixture is specified, Class B aggregate may be blended with Class A aggregate to meet requirements for Class A materials. When blending Class A and B aggregates to meet a Class A requirement, ensure that at least 50% by weight or volume of the material retained on the No. 4 sieve comes from the Class A aggregate source. Blend virgin aggregate with native LRA aggregate in the percentages shown in Table 4. When blending, do not use Class C aggregates.
2.3.2. LRA Aggregate. Native LRA aggregate consists of limestone impregnated with naturally occurring asphalt.
LRA aggregates that contain less than 1% of naturally occurring asphalt are defined as white rock. Each ftp://ftp.dot.state.tx.us/pub/txdot-info/cmd/mpl/brsqc.pdf ftp://ftp.dot.state.tx.us/pub/txdot-info/cmd/mpl/brsqc.pdf

4.4.2. Job-Mix Formula for LRA Mixtures. Provide a job-mix formula (JMF) design report for a paving mixture that meets the requirements of Tables 3, 4, and 5. Identify in the report the combined aggregate gradation, the percentage of each material component used in the mixture, and results of all applicable tests. Obtain approval of the JMF before starting production. With approval, the JMF target values may be adjusted as needed within the percentage point tolerances of Table 6 without a laboratory redesign of the mixture. If the adjustments exceed the tolerances shown in Table 6, MTD may require a new mixture design. Adjustments must not exceed the master gradation for the type of mixture specified on the plans.
