AASHTO T 167-10 (2019) outlines the procedure for measuring the compressive strength of compacted asphalt mixtures. This standard is applicable to both laboratory-fabricated specimens and mixtures produced in a hot-mix plant. The aim of this test method is to evaluate the structural integrity and load-bearing capacity of the hot-mix asphalt.

The standard provides detailed instructions for preparing the specimens, including weighing, batching, mixing, and fabricating the asphalt mixtures in the laboratory. It also provides guidance on the selection of test conditions, such as temperature and curing time, to ensure accurate and consistent results. The compressive strength is then measured using a hydraulic testing machine, which applies a gradually increasing compressive force to the specimen until failure occurs.

By determining the compressive strength of hot-mix asphalt, this method helps assess its suitability for various applications, such as highways, roads, parking lots, and airports. The results obtained from this test can be used to optimize asphalt mix designs, evaluate the quality of asphalt materials, and ensure compliance with specifications and performance requirements.
