What is asphalt rice test?

The Rice Test for Specific Gravity of Asphalt is a common test that measures the Theoretical Maximum Specific Gravity (Gmm) of asphalt specimens. The test is an integral part of quality assurance of asphalt mixtures. Free and entrapped air is removed from the asphalt sample to prepare for the test.Click to see full answer. Considering this, what is a rice number for asphalt?The maximum unit weight is also sometimes called the “solid density”. This value is based on the asphalt mixture’s maximum specific gravity – also known as the Rice value or G mm in Superpave. Then, if 95% compaction is specified, the minimum acceptable unit weight is: 0.95 X 156.0 = 148.2 PCF.Beside above, how do you calculate asphalt in GMM? Theoretical maximum specific gravity is determined by taking a sample of loose HMA (i.e., not compacted), weighing it and then determining its volume by calculating the volume of water it displaces (Figure 1). Theoretical maximum specific gravity is then the sample weight divided by its volume. Also know, what is specific gravity of asphalt? Asphalt Specific Gravity. The specific gravity at 15.6° C (60° F) is commonly used when buying/selling asphalt cements. A typical specific gravity for asphalt is around 1.03.What are air voids in asphalt?Air voids are the percentage of void spaces within the aggregate–binder matrix that are not filled with binder—sufficient voids should be provided to allow for a slight amount of additional compaction under traffic and a slight amount of asphalt expansion due to temperature increases, without flushing, bleeding, or
