B-2. Hot-mix recycling problem.
The middle 75 feet of a runway is to be removed full depth (3 inches) and replaced with a recycled asphalt mixture
containing 50 percent reclaimed asphalt pavement. Develop the design mix.
a. Step 1. Obtain samples of the in-place pavement (use jackhammer or other acceptable means) along with samples
of the new aggregates to be used and the new asphalt and recycling agent, if needed.
b. Step 2. Run sieve analyses on all aggregates including aggregate extracted from sample of the in-place asphalt
mixture. If an adequate history upon which to evaluate the new aggregate is not available, use the standard tests as outlined
in TM 5-822-8/AFM 88-6, chap 9, and TM 5-825-2/AFM 88-6, chap 2. The history of the performance of the old
aggregate should suffice for its evaluation. The aggregate gradations are shown in table B-1.
