  • Abstract:
    Low temperature cracking is one of the major ; distress modes in asphalt pavement and is ; disastrous to pavement performance and service ; life. A poor riding surface leads to an increase in ; maintenance and eventual early replacement of ; the pavement. Currently, there are two ; approaches to characterize the low temperature ; thermal cracking potential of asphalt concretes; (1) ; mechanistic-empirical analysis (Superpave ; Indirect Tensile Creep and Strength Test, IDT) ; and performance model and (2) a torture test ; (Thermal Stress Restrained Specimen Test, ; TSRST). Both methods have been validated with ; field performance data and predict the low ; temperature cracking potential of asphalt concrete ; mixes. However, neither test can be readily used ; as a routine test because of the complex test and ; analysis procedures for IDT and the costly ; specialized equipment, and the difficulty ; producing beam specimens for TSRST. A new ; simple test procedure is needed to evaluate the ; low temperature cracking potential for a single ; severe freezing event and thermal fatigue for the ; environment and materials commonly used in ; Ohio.
