Guidelines for Using Geosynthetics with Hot-Mix Asphalt Overlays to Reduce Reflective Cracking

Abstract

This paper provides complete guidelines for using geosynthetics with hot-mix asphalt overlays to reduce reflective cracking. Definitions of the various types of geosynthetics that are commercially available along with some of their advantages and disadvantages are also provided. These guidelines address the following: when to consider a geosynthetic product, how to select and store geosynthetics, cost considerations, pavement design with a geosynthetic, overlay construction with a geosynthetic, construction inspection, and potential construction problems.
