Question

In a Marshall test, the percentage of asphalt binder by total weight of aggregate is 5.26 percent. The bulk specific gravity of aggregate (Gsb) = 2.455, the specific gravity of asphalt binder (Gb) =1.020, and the density of water (w) = 1.000 g/cc. If the effective asphalt binder content (Pbe) is 3.6 percent by total weight of mixture, and the voids in mineral aggregate (VMA) is 14.0 percent by the total (bulk)volume of mixture, determine the following volumetric properties of the asphalt mixture:

1. The absorbed asphalt (Pba), percent by total weight of

aggregate.

2. The bulk specific gravity of the compacted mixture (Gmb).

3. The voids in total mixture (VTM), percent by total volume of

mixture.

4. The theoretical maximum specific gravity of the loose mixture

(Gmm).

5. The voids filled with asphalt (VFA), percent by volume of total

voids.

6. The effective specific gravity of the aggregate (Gse).
