Another asphaltic concrete mixture consists of 42% coarse aggregates, 51% fine aggregates, and 7% mineral fillers. The respective bulk specific gravities of these materials are 2.600, 2.710, and 2.690. The asphalt cement content of the total weight of the mix of a sample is 5.5%. The bulk specific gravity of the sample was calculated as 2.467, and the maximum bulk specific gravity of the mix was estimated using ASTM D2041 as 2.562. Determine the value of the sample's air voids,...
A bituminous mixture contains 65% coarse aggregate, 35% fine aggregate (by weight of total aggregate) and 4.8% asphalt (by weight of the mixture). Determine the bulk specific gravity of the mixture if, after compaction, it contains 7.0% air voids. Assume that the aggregate absorbs 0.3% of the asphalt by weight of the aggregate. The specific gravities of the materials are: Coarse Aggregate 2.723 Fine Aggregate 2.664 - 1.05
The Data given,
An asphalt concrete specimen has the following properties: 1. Percent air voids in the compacted mix (VTM) 2. Voids in mineral aggregate (VMA) 3. Voids in mineral aggregate filed with asphalt (VFA) 4. Bulk specific gravity of compacted mix 5. Maximum (Rice) theoretical specific density 6. Plot VFA vs. binder content (i.e. 5 % , 5.5 % , 6%, and 6.5 % ) ( The specific binder content will be determined by the TA during lab depending...
