104 NCHRP 46-05 -- RAP and RAS -- Materials Engineers Introduction Standard laboratory practices and procedures have been developed and/or adapted in order to handle, mix, and test these mixtures within each agency. The main focus of this survey is to document mix design and testing experiences of those folks by actually working with high RAP, RAS, or RAP/RAS combinations in the laboratory.
