Development of an Analytical Model to Predict Volumetric Properties

摘要

The joint Montana DOT-ATSER research project focused on evaluating an analyticalmethod for estimating Marshall and Superpave mix design procedures for Hot Mix Asphaltic Concrete. This project was to divided into two phases. In Phase 1, a literature review of the state of the art in the design of Hot Mix Asphaltic Concrete was performed. In Phase 2, the actual methods of predicting mix designs were evaluated. This report evaluated the ATSER method of estimating volumetric properties without preparing laboratory specimens. Existing methods of determining volumetric properties were evaluated. The study revealed that the Hudson and Davis method (Hudson and Davis, 1965) did not correlate well with actual mix designs. However, the Hensley method (Hensley, 1985) correlated well, although required final test data. The ATSER method utilized basic engineering properties to evaluate the proposed job mix formulas. The method proved to provide an excellent estimation of actual volumetric properties. A new method of estimating volumetric properties was utilized in this study. The method is
