ASTM D6372-15 PDF Download

ASTM D6372-15 is a standard practice that provides guidance for the design, testing, and construction of microsurfacing. It is important to note that this standard is not intended to be used as a specification, but rather as a guide. It recommends adapting end use specifications according to job and user requirements.

The practice covers the use of polymer modified asphalt emulsion, mineral aggregate, mineral filler, water, and other additives in the creation of mixtures. These mixtures are properly proportioned, mixed, and spread on a paved surface. It emphasizes the need for testing and ensuring that the materials are appropriately combined and applied.

The standard also acknowledges that there might be test methods referenced in the practice that fall outside the jurisdiction of ASTM and may or may not have a precision statement. This suggests that additional testing methods may be required to ensure the quality and performance of microsurfacing.
