Guidelines on the Use of RAP in Routine Maintenance Activities
The overall objective of this study was to determine the most economical and effective uses for asphalt pavement millings. Specific objectives include (1) determine existing effective uses of milled RAP, (2) determine effectiveness of new untried ideas and improvements on existing uses through field experimentation, and (3) provide the Department with a mode of implementation. Most of the uses addressed in this study refer to routine maintenance applications. This document presents guidelines on the use of RAP in routine maintenance activities. Guidelines are offered concerning proper procedures for collecting and stockpiling RAP. Cold-mix design procedures and field tests are outlined for aid in determining appropriate recycling agent quantities, and instruction is given for field processing procedures to improve the quality of RAP for maintenance mixtures. Guidelines are also provided as to the appropriate uses for RAP and treated RAP in routine maintenance activities.
In this study, RAP was blended with recycling emulsions and conventional maintenance mixtures in attempts to improve its field performance as a mainte...
