Abstract:

Given the importance of the quality of asphalt binder in resisting crack growth in asphalt mixtures, there is a critical need for a simple and accurate test to evaluate the cracking resistance of asphalt binders. Most current tests are based on rheological indices and do not induce cracking in asphalt binders. Researchers have developed a simple “poker chip” test to evaluate the cracking resistance of asphalt binders in terms of its ductility. The test method is simple, repeatable, sensitive, accurate, and does not require significant capital investment. This project demonstrated the sensitivity of the poker chip test to asphalt binder modifiers including polymers and chemical modifiers, polymer content, reclaimed asphalt pavement, and aging. This project also demonstrated that the test and resulting parameters are strongly related to the propensity of the asphalt pavement to crack. A study of 22 field sections from different geographic regions within Texas showed that 86% of field sections that had a ductility below 150% showed some form of cracking in the asphalt layer. This report presents the findings from this study as well as a standard method for adoption.
