AASHTO PP 94-18 (2020) PDF Download

AASHTO PP 94-18 (2020) is a standard specification that provides guidelines for determining the optimum asphalt content of cold recycled mixture with foamed asphalt. This standard is specifically designed for use in cold recycling mix design processes, which involve the reuse of existing asphalt pavements through cold in-place recycling (CIR) or cold central plant recycling (CCPR) methods.

The standard outlines the procedures to be followed when determining the amount of foamed asphalt, water, and other additives required for the cold recycled mixture. These determinations are based on the desired strength properties of the mixture.

By following the guidelines provided in AASHTO PP 94-18 (2020), engineers and practitioners can effectively design and produce cold recycled mixtures that meet the specified performance requirements. This standard ensures that the mixture is optimized for its intended application, taking into account factors such as traffic loads, climate conditions, and environmental considerations.
