Stability of Open-Graded Bases under Wheel Loads Using a Model Testing Approach

Abstract

The stability of open-graded bases of various gradations and types of aggregates were examined when subjected to traffic. A small scale test box was designed and constructed to contain the base materials to be tested. Traffic was applied with a tire load directly on top of the bases. Rut depths at the deepest point of the wheel path were taken and used as a measurement of the stability of the material. Six different gradations of two types of materials were tested and compared with the performance of the US Army Corps of Engineers standard crushed stone base coarse gradation. Recommendations are given as to the type of material and gradation that would be most stable under direct traffic.
