Laboratory Screening of Durable Aggregates for Paving Asphalt Mixture
Incompatible and poor quality aggregates used in pavement construction result in different types of distresses and pavement failure which has been recognized as one of the major problems to most state Departments of Transportations (DOTs) and highway agencies. It is believed that the use of good quality aggregates can exhibit a good bonding with asphalt binders and minimize this problem significantly. This study aims to identify suitable aggregates used in Arkansas for durable pavement construction. The Arkansas Department of Transportation (ARDOT) approved four types of aggregates (sandstone, limestone, gravel, and dolomite) from four different sources have been evaluated in this study. The physical, mechanical, and chemical properties of aggregates have been determined by performing a series of laboratory tests. Also, the work of adhesion and boiling resistance tests have been conducted to predict the performance of the asphalt mixtures made of these aggregates and binder. The findings of this study are expected to help pavement researchers and highway professionals to find appropriate aggregates in constructing the durable pavements.
