AASHTO PP 83-16 (2020) PDF Download

AASHTO PP 83-16 (2020) is a standard practice for designing micro surfacing mixtures. Micro surfacing is a thin overlay that is applied to existing asphalt pavements to restore and protect them from further deterioration. This standard provides guidelines for determining the appropriate proportions of materials needed for micro surfacing mixtures.

The practice utilizes mixture properties to determine the quantities of various components, including polymer-modified emulsified asphalt, mineral aggregate, water, mineral filler, and additives. These materials are combined to create a job-mix formula that meets the specific requirements of the project.
