AASHTO MP 37-18 (2020) PDF Download

AASHTO MP 37-18 (2020) is a standard specification that pertains to performance-graded asphalt binder used for surface treatments. This standard focuses on assigning grading designations to binders based on their ability to perform under specific temperature conditions. The grading designations are determined by considering the average seven-day maximum pavement surface design temperature and the minimum pavement surface design temperature.

The standard specifically addresses surface treatment applications such as seal coats and chip seals, which are commonly used to protect and enhance the performance of road surfaces. By providing guidelines for the selection and grading of asphalt binders, the standard ensures that the binders used in surface treatments are suited to withstand the anticipated temperature variations and environmental conditions that the treated surfaces may encounter. Adhering to this specification promotes the durability and longevity of surface treatments, ultimately contributing to the overall quality and performance of roadways.
