• Abstract:
  The guide for selecting mixtures for flexible pavements will provide the designers with recommendations for selecting mix types based on factors such as traffic, speed and expected performance. The guide covers mixes such as regular dense mixes Item 340 and 341, permeable friction course (PFC) Item 342, performance design mixes Item 344 and stone matrix asphalt mixes (SMA) Item 346. This guide is intended to provide general recommendations based on the Texas experience. This guide was developed based on the survey conducted under the project 0-4824 (Guidelines for Selecting Asphalt Mixtures and Evaluation of Polymer-Modified Mixes). In the end, an expert system (http://pavements.ce.utexas.edu/TexSys) has been developed that can be used for selecting mix types. The purpose of the expert system is to provide guidance on selection of HMA types for different applications after HMA thickness has been determined from FPS 19 or other available flexible pavement design guides.
