DEVELOPMENT OF A METHOD FOR MEASURING WATER-STRIPPING RESISTANCE OF ASPHALT/SILICEOUS AGGREGATE MIXTURES
This Innovations Deserving Exploratory Analysis (IDEA) project developed a nondestructive method for measuring the water stripping resistance at the molecular level of asphalt/siliceous aggregate mixtures using the technique of Fourier Transform Infrared Spectroscopy-Multiple Internal Reflection (FTIR-MIR). This report summarizes the research and presents the results on the use of the spectroscopic technique for evaluating the effectiveness of different antistripping agents for asphalts. Also, based on the interfacial water information, the mechanisms of stripping of an asphalt from a siliceous aggregate and of the transport of water from the environment to the asphalt/aggregate interface are presented.
