Development of a SFE Database for Screening of Mixes for Moisture Damage in Oklahoma
Moisture-induced damage is one of the major distresses responsible for deterioration of asphalt pavement at early age. There is a need to identify mechanistic methods for evaluating moisture-induced damage as the conventional test methods, such as Hamburg wheel tracking test (HWT) and indirect tensile strength test (IDT) do not address the mechanism leading to failure of asphalt pavements. In this study, surface free energy (SFE) technique were used to mechanistically quantify bonding characteristics of aggregate-asphalt binder systems and consequently moisture-induced damage potential of asphalt mixes. For this purpose, unmodified and polymer-modified asphalt binders from four different sources were collected and mixed with different additives, such as warm mix asphalt (WMA) additive, anti-stripping agent (ASA), polyphosphoric acid (PPA) and reclaimed asphalt pavement (RAP). The SFE components of the binder blends were determined using two different methods, namely, dynamic Wilhelmy plate (DWP) and sessile drop (SD) test. Also, the SFE components of aggregates from five different sources were determined using universal sorption device (USD) and sessile drop (SD) test. Fourier transform infrared, X-ray fluorescence and total acid number tests were conducted on the blended binders to understand the effects of chemical compositions on the SFE components. Asphalt mixes consisting of different additives were produced in the laboratory for moisture-induced damage evaluation using HWT, IDT and Louisiana semi-circular bend (LASCB) tests. Correlations between the moisture-induced damage performance parameters from laboratory performance tests and the SFE technique were investigated. The SFE technique was found to be able to differentiate asphalt mixes with different additives based on their moisture-induced damage potentials. It was also found that the LA-SCB test with moisture induced sensitivity test (MIST) conditioning can be used as an alternative method to conventional moisture-induced damage test. As a part of this project, a SFE database of asphalt binders and aggregates was developed. The database is expected to be helpful to screen materials during mix design.
