Minimum Crushed Aggregate Requirements, Haiming Huang, Thomas D. White

JTRP Technical Reports

An accelerated pavement testing facility has been developed by Purdue University for the Indiana Department of Transportation. The test facility includes a test pit in which prototype scale pavement sections can be installed. The Accelerated Pavement Tester loading system has the capability of applying moving wheel loads to the test sections. An initial study utilizing the accelerated pavement test facility has been conducted at Purdue University to determine the minimum crushed aggregate requirements in asphalt mixtures in Indiana. This study addresses effects of various constituents of the asphalt mixture on pavement rutting. The factors included in this study are aggregate …
