Resilient Moduli of Raw and Stabilized Aggregate Bases and Evaluation of Layer211 Coefficients for AASHTO Flexible Pavement Design. Volume 1

摘要

A comprehensive study involving laboratory testing of resilient moduli (MR) of211u001eaggregate materials, determination of layer coefficients, and their application 211u001ein AASHTO flexible pavement design was conducted. Three coarse aggregates, 211u001enamely, Richard Spur (RS) Sawyer, and Meridian, that are commonly used as 211u001esubbase/base of roadway pavements in Oklahoma were selected. Based on the Los 211u001eAngeles abrasion values, the RS and the Sawyer aggregates are considered good 211u001equality aggregates, whereas the Meridian is considered a marginal aggregate.
