Effect of Polymer Modified Asphalt Binders on the Performance of the Asphalt Concrete Mixes Used in Hawaii

The characteristics of the binder in an asphalt concrete mixture have a significant effect on the mixture behavior. The selection of the asphalt binder directly affects some distress modes observed locally in pavements such as rutting, fatigue cracking, and raveling. Not only do these distress modes have adverse effects on the quality of ride that the State DOT is able to provide to the public but also they significantly reduce pavement life. A number of different modified asphalt binders have been developed to improve the rutting, fatigue cracking, and thermal cracking problems of hot mix asphalt (HMA) by altering the properties of the asphalt cement binder. However, existing testing protocols do not currently rank the modified binders relative to their contribution to avoid mixture damage. Further, the literature on mix characterization produced with modified asphalt binders indicates that aggregates distinctly different from the basaltic aggregates found in Hawaii have been used in most studies and that only a limited number of the possible mix combinations have been explored. Even though many advances have been made in the understanding of mixture performance, no universal performance model has been developed that accounts for all the variables that may affect the deterioration processes. Increased traffic demands will place higher demands on the use of higher quality materials and will require tools to evaluate their cost-effectiveness in reducing pavement distresses. Other research studies indicate that producing asphalt concrete mixes with polymer-modified asphalt binders can be a cost-effective way to reduce pavement distress. The proposed research, therefore, aims at: 1) Confirming the inadequacy of existing binder characterization protocols to rank the polymer-modified binders relative to the contribution to mixture damage and validating the usefulness of recently proposed protocols for neat asphalt and polymer-modified asphalt binder characterization; 2) Evaluating, through extensive laboratory testing of asphalt concrete mixes, the improvements in rutting performance of mixes prepared with the different polymer-modified asphalt binders locally available over mixes prepared with neat asphalt binders under different loading and environmental conditions; 3) Providing information useful to produce test sections for field validation and for the development of pavement deterioration models for Hawaii; and 4) Providing an estimate of the life cycle costs associated with the use of modified-asphalt binders and assessing their feasibility for use in Hawaii.
