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...

Problem-6 An asphalt concrete mixture is to be designed according to the Marshall procedure. A PG 64-22 asphalt cement specific gravity of 1.00 is to be used. A dense with a aggregate blend is to be used, with a maximum aggregate size of 3/4 in. and a bulk specific gravity of 2.786. The theoretical maximum specific gravity of the mix at asphalt content of 5.0 % , is 2.490. Trial mixes were made with average results as shown in table...
