PERFORMANCE ANALYSIS OF AN EXPERIMENTAL FIELD PROJECT UTILIZING ASPHALT MODIFIERS

Utilization of a mix design that will resist rutting and cracking is crucial to the life expectancy of a pavement. Drainage problems associated with these distresses contribute to safety problems and accelerated pavement deterioration. In an effort to combat rutting and cracking in Montana, a series of experimental test sections utilizing polymer modifiers were installed in 1991 along the I-94 Prairie County Line West Project, in eastern Montana. These sections were to be monitored for a period of five years by Montana State University, Bozeman. This report focuses on results of the five year monitoring of the polymer modified test sections. A summarization of the interim reports is included. The findings of this study indicate that utilization of polymer modifiers has quantifiable benefits. These benefits extend beyond improvements in resistance to rutting and cracking, and into resistance to raveling, weathering, and bleeding.
