Test Methods for Verification of Low-Temperature Cracking Resistance of Asphalt Binders and Mixtures

Low-temperature cracking continues to be the number one distress in Minnesota. While progress has been made in developing fracture mechanics tests to obtain relevant material properties, there is a need to develop simpler test methods and analyses that can be used on a routine basis and at lower costs to verify the properties of asphalt materials used in construction of Minnesota pavements. These test methods are: ...more »

Why is this a priority and what are the benefits for the State/County/City? :

In order for performance testing to be fully implemented in MN quick, reliable test procedures are needed so that construction acceptance decisions in a timely manner.

 

Primary benefits to road owners and industry include improved procedures for specifying and designing asphalt mixtures in light of heightened sustainability requirements and project-specific performance requirements, reduced construction costs, extended pavement life and reduced maintenance costs.
