Lime-Fly Ash-Aggregate Base Course with Class C Fly Ash

摘要

The study evaluates the performance of a lime-fly ash stabilized base courseusing Class C fly ash constructed on a highway paving project. The stabilization consisted of a six-inch thick lime-fly ash-aggregate (LFA) mixture utilizing low pasticity sand aggregates. Data was collected through visual observations, photographic documentation, distress surveys, core evaluation, and deflection testing over a three year period. Project data exhibited a very successful undertaking using Class C fly ash in an LFA mixture as a base course alternative.
