AASHTO MP 32-17 (2019) outlines the requirements for various materials used in slurry seals. These materials include emulsified asphalt, aggregate, mineral filler, water, and additives.

The standard applies to the production and placement of slurry seals, which are thin surface treatments applied to existing pavement surfaces to improve durability, skid resistance, and overall performance. Slurry seals are commonly used for preventive maintenance to extend the life of roadways.

The specification ensures that the materials used in slurry seals meet certain quality standards. For example, it provides guidelines for the performance characteristics of emulsified asphalt, such as viscosity and residue content, as well as the properties of aggregate, such as gradation and hardness. It also specifies requirements for the mineral filler, water, and additives used in the slurry seal mixture.
