Integrated Material and Structural Design Method for Flexible Pavements. Volume 3. Laboratory Design Guide

摘要

The research quantified relationships between structural and material mix design parameters and documented a laboratory test procedure for examining mix design from a structural viewpoint. Laboratory asphalt mix design guidelines are presented. The guidelines are based upon the analysis of the results of laboratory static and cyclic load triaxial, indirect tensile, and flexural beam tests. The guidelines allow the highway engineer and the laboratory technician to tailor the asphalt mix design procedure to optimize the structural properties of the mix. Two mix design methods are covered: the Marshall mix design with minor modifications and the indirect tensile test. Analytical and statistical equations are also included to be able to calculate or estimate the structural properties of the mix.
