Construction and Comparison of Louisiana's Conventional and Alternative Base Courses Under Accelerated Loading.

摘要

This report describes the test results of the first project at the Louisiana Transportation Research Center's Accelerated Loading Facility. In 1995, nine test lanes were constructed at the Louisiana Pavement Research Facility(PRF) in Port Allen, Louisiana. These test lanes consisted of 3.5 in of type 8 wearing and binder course and crushed limestone or soil cement bases made with either four percent or ten percent cement and either plant-mixed or mixed in-place courses. These mixed courses had the same structural capacity but with variable shrinkage cracking potentials. The lanes were loaded to failure using the AZccelerated Loading Facility(ALF) and the results were used to compare the performance of the various base materials.
