Evaluation of SHRP Indirect Tension Tester to Mitigate Cracking in Asphalt Concrete Pavements and Overlays
Severe environmental and traffic loading conditions make premature cracking of asphalt concrete pavements and overlays a continuing problem in Florida. The primary reason for this problem is that mixture properties that control cracking are not currently measured, specified, or controlled. Consequently, asphalt mixture properties that control cracking have not been incorported into existing design procedures for pavements and overlays. This situation results in an inability to effectively design mixtures and pavements that resist cracking, which in turn results in wasted dollars. Therefore, there is a clear and urgent need to identify and implement a practical and effective test to measure, specify, and control relevant mixture properties to mititgate cracking in asphalt concrete pavements and overlays. For effective design of overlays, the test should also be suitable for determining relevant properties of mixtures within existing pavements. The indirect tensile tester (or indirect tensile creep and failure test) developed as part of the Strategic Highway Research Program (SHRP IDT) has the potential to meet the needs stipulated above.
