(1) by total mix
(2) based on bulk gravity
(3) AASHTO T305 conducted at mix production temperature (not compaction
temperature)
(4) Nini and Nmax do not apply
(5) VCA = Volume of Coarse Aggregate (Calculated for mix and dry rodded conditions
per AASHTO PP41- 02 or newer version.)
(6) Unconditioned specimens will have a minimum 65 psi (450 kPa) retained strength.
Compact specimens at 300 ºF (149 ºC) for PG 70-22M and 310 ºF (154 ºC) for
PG 76-22M.
B. Asphalt Binder. Provide asphalt binder conforming to 702.01.
C. Coarse Aggregate. Use approved coarse aggregates. Ensure coarse
aggregates meet 703.05 and Table 443.03-3.

D. Mineral Filler. Conform to 703.07. Use mineral filler in the JMF with a
plasticity index (AASHTO T 90) not greater than 4 (does not apply to hydrated
lime). Reclaimed asphalt concrete pavement passing the 5/8 inch (16 mm) sieve
may be used as filler only. Do not account for reclaimed asphalt concrete
pavement binder content. Do not use quicklime (CaO). Do not premix filler with
another aggregate. Cover mineral filler piles to protect from rain.
Blend the mineral filler, asphalt binder and fiber stabilizer into a homogenous
mixture and test the mortar for the following properties of Table 443.03-4.
