Pilot Test of Proposed Standard Practice for Recycling Agents in Asphalt Mixtures Incorporating RAP and RAS
The objectives of this implementation project are to (1) apply the proposed AASHTO Standard Practice and evaluation tools produced in NCHRP Project HR 09‐58 to the recycled binder blends and mixtures associated with field evaluation projects in two climates and independently assess their effectiveness and determine if revisions are needed, (2) provide guidance on the production and construction of mixtures with high recycled binder ratios (RBRs) and high recycling agent dose, and (3) develop a guide for DOTs to evaluate the potential implementation of the proposed AASHTO Standard Practice on field projects built in their states.
