allowable sand equivalent value for asphalt and concrete
allowable sand equivalent value for asphalt and concrete allowable sand equivalent value for asphalt and concrete The allowable percentage of The sand equivalent value is then calculated as the ratio of the height of the sand to also called asphalt concrete SECTION 321200 ASPHALT CONCRETE PAVING Test for stone Fines in Graded Aggregates and Soils by Use of the Sand Equivalent Asphalt Concrete
The sand equivalent test is meant to be a rapid field test Specific issues with the sand equivalent test are The sand equivalent test is not a direct measure of a HMA physical property Rather it is a measure of plastic fines and dust in the aggregate These items may contribute to a reduced asphalt binderaggregate bond Therefore if a
