AASHTO PP 86-20 PDF Download

AASHTO PP 86-20 is a standard practice that provides guidelines for determining the emulsified asphalt content in cold recycled mixture designs. This standard is applicable to cold recycling methods such as cold in-place recycling (CIR) and cold central plant recycling (CCPR). The primary objective of this standard is to ensure the desired strength and performance properties of the recycled mixture.

The standard outlines the process of evaluating the amount and composition of emulsified asphalt and other additives that are necessary for achieving the desired mixture properties. This includes determining the appropriate emulsified asphalt content based on strength requirements and considering other factors such as traffic conditions and environmental conditions.
