What is the primary goal of a field test for asphalt mixtures?

The primary goal of a field test for asphalt mixtures is to confirm adherence to design specifications. Field tests are crucial because they provide verification that the asphalt mix being produced and applied meets the required standards and performance characteristics established in the design phase. This involves checking various properties of the asphalt, such as density, temperature, and compaction, which are essential for ensuring that the mixture will perform adequately under real-world conditions. By performing these tests, engineers can ensure that the final product will withstand traffic loads, environmental factors, and other stresses during its service life, ultimately contributing to the longevity and safety of the pavement.
