asphalt gradation testing

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.

SPECIFICATIONS FOR ASPHALT PAVING, MATERIALS, SAMPLING, AND ...

properties, gradation and asphalt cement content. Costs for the trial plant mixes and laboratory testing are at the contractor’s expense. Warm Mix Asphalt, as outlined in OPSS 310 - Appendix C, is required when the minimum ambient temperature conditions for paving set out in Section 12.2 of this specification, are not satisfied.

EFFECT OF AGGREGATE GRADATION ON PERMANENT DEFORMATION ...

need to evaluate the effect of aggregate gradation on measured asphalt content so that an adjusted asphalt content which is closer to the asphalt content actually incorporated in the HMA mix, can be ascertained. PROJECT DETAILS The test data for this study was obtained from a major 4-lane interstate paving project in Pennsylvania.

Testing Asphalt With Ignition Burn-off Ovens | Roads & Bridges

Dec 28, 2000 · Tempyrox has developed ovens for cleaning asphalt from laboratory glassware, which may also be used in the ignition method to test asphalt content and aggregate gradation. However, because their ovens operate at a lower temperature, ignition never takes place and the burn-off of asphalt will be much slower.
