PDF Volumetrics in Asphalt Mixtures

The proportion of asphalt in the mixture is critical and must be accurately determined in the laboratory and then precisely controlled on the job. The optimum asphalt content of a mix is highly dependent on aggregate characteristics such as gradation and absorptiveness. Aggregate gradation is directly related to optimum asphalt content.

Gradation Test - Pavement Interactive

The gradation and size test (Figure 1) is used to determine aggregate particle size distribution. Size distribution is perhaps the single most important aggregate quality associated with the control of HMA mixtures. Aggregate gradation and size affect HMA volumetric properties as well as mixture permeability and workability.

Asphalt Friction Testing Gets New Standard | AsphaltPro

Recent advances in laboratory polishing and friction testing now provide a better assessment of friction that considers the entire gradation in an asphalt mixture rather than a single aggregate source. The dynamic friction tester (DFT) gives a better assessment of the friction of a pavement surface.

a test sample of desired size is obtained. (5) Store the portion that has been set aside for possible check testing. 2. Accurately weigh the wet sample. Record this wet weight on a moisture worksheet. This material will not only be used for the gradation test but also for the moisture test. Example: 5922 grams. 3. Dry aggregate sample thoroughly.
