Potential Use and Applications for Reclaimed Millings: Report of Findings and Recommendations for Other Applications for Reclaimed Millings. Task 5.2: Report of Findings and Recommendations for Other Applications.

摘要

The purpose of this project was to provide support to PennDOT District 1-0 in the effective use of milled asphalt material. Specifically, District 1-0 has a shortage of high-quality available coarse aggregate and has developed the innovative procedure of breaking down and sorting recycled asphalt pavement (RAP) to recover the older high-quality aggregate for use on higher-volume roadways. The focus of this project was on the usage of the remaining asphalt and fines. This report documents Task 5. The objective of Task 5 was the laboratory exploration of two promising applications for the reclaimed fine millings. The two applications investigated were use of the reclaimed millings in thin cold-mix overlays, and the possibility of using a cold mix of the reclaimed millings with virgin-grade C aggregates to replace the scalped #8 aggregates for binder course or low-volume secondary roads.
