Unformatted text preview: SuperPave specifications. Results of laboratory testing were as follows: a. Gmb=2.433, Pa=3%, and Gsb=2.712 b. Gmm=2.536 If the traffic volume expected on this road was 2 million ESALs, determine whether this mix conformed to the SuperPave VMA, VFA, and Air Voids requirements. 8. Concrete is required for an interior slab on grade in Louisiana. The 28-day compressive strength should be 4,000 lb/in 2 . The slump should be between 3 and 4 in. and the maximum aggregate size should not exceed 1 in. The properties of the materials are as follows: a. Cement : Type II, specific gravity = 3.15 b. Coarse Aggregate: Bulk specific gravity (SSD) = 2.68; absorption capacity = 0.5%; dry-rodded unit weight = 95 lb/ft3; surface moisture = 1% c. Fine Aggregate: Bulk specific gravity (SSD) = 2.59; absorption capacity = 1.0%; fineness modulus = 2.80; surface moisture = 2.1%. What is the mix design?...
