Abstract

The Minnesota Road Research Project (MnROAD) and the National Center for Asphalt Technology (NCAT) have formed a partnership to execute asphalt mixture performance testing experiments with a nationwide implementation impact. As part of this partnership, a pooled-fund study, called MnROAD Cracking Group (CG) experiment, was conducted to identify laboratory experiments that can best address low-temperature cracking performance. The construction of the test cells at MnROAD was done in 2016 and original binders and loose mix were collected and used to prepare testing specimens for laboratory experiments. In this paper, the viability of using three test methods for asphalt mixtures and one test method for asphalt binders in the material selection process, quality control, and forensic investigations of asphalt paving materials is discussed. These test methods are the Bending Beam Rheometer (BBR) for creep and strength of asphalt mixtures; low temperature SCB (Semi-Circular Bending) fracture testing for asphalt mixtures; |E*| (Dynamic Modulus) testing of asphalt mixtures using the IDT (Indirect Tensile) configuration; and BBR strength testing of asphalt binders. First, the materials used are described and the test methods are discussed. The experimental results are presented and statistical tools are used to identify significant factors in predicting low temperature cracking resistance of the set of asphalt materials used in the CG experiment. Conclusions are drawn based on preliminary field performance data.
