12SP501(E) RECYCLED HOT MIX ASPHALT MIXTURE OF LOCAL AGENCY PROJECTS -
This Special Provision requires "bumping down" the low temperature grade for Marshall mixtures produced with RAP in Tier 2 (18-27% binder replacement). This SP should begin being used with the January 10, 2014 letting.
In many areas of the state, this SP will require the use of -34 binders when producing in Tier 2. APAM has recently met with MDOT, CRAM and FHWA representatives to discuss our concerns regarding cost impacts and, under some circumstances, possible performance issues associated with this SP. Follow-up discussions are planned.
