PPRC14 SPE 3.30: Standard Materials Library and Guidance

The objective of this project is to test and include additional regional materials in the California Department of Transportaiton (Caltrans) mechanistic-empirical (M-E) Standard Materials Library, including base, subbase and new recycled materials. Implement procedures to simplify the selection of material types for ME design by district designers, and develop guidance for asphalt mix designers to meet performance related mix design requirements. This study is a continuation of Task 2356. Specific objectives include: (1) laboratory testing; (2) field testing; (3) materials selection guidance; (4) performance based mix design guidance; and (5) project report.
