Developing Specifications for Using Recycled Asphalt Pavement as Base, Subbase or General Fill Materials
Reclaimed Asphalt Pavement (RAP) stockpiles in Florida have been growing due to rehabilitation of the state's roadways. At this time the major use for RAP is an aggregate in Hot Mix Asphalt (HMA) production. The application of RAP as a Florida Department of Transportation (FDOT) approved base course, subbase, and subgrade has been hindered due to low reported laboratory LBR tests. A thorough laboratory and field investigation was conducted to evaluate the basic engineering behavior of RAP and to analyze its field performance. The lab studies focused on evaluating the Limerock Bearing Ratio performance of RAP and developing a database of the elementary geotechnical strength parameters such as friction, cohesion and elastic modulus. An initial lab study enabled LBR characteristics to be evaluated using several compaction techniques. RAP for this portion of the work was taken from a stockpile of material that was not processed after milling from the pavement surface.
