Asphalt mixture was prepared in the lab using 4.8% (by the weight of total mixture) of asphalt binder with specific gravity Gb-1.015 and aggregate with Gsb-2.652. The bulk specific gravity of the mixture (determined on compacted specimen) was Gmb- 2.350. a) Determine the masses and volumes of the components needed to make 1m³ of the mixture and enter these values on the diagram show below Mass, kg Volume, m³ Air voids Asphalt Aggregate 1 m³ Vv VTM = 100% Vm VMA = VFA = Vy + V be Vm Vbe Vbe + V₂ . (1) 100% (2) 100% (3) b) Assuming that the absorption of the aggregate is 0.0% (that is no asphalt will be absorbed by the aggregate), calculate the values of VTM, VMA and VFA. using definitions provided in the "HMA volumetric handout" accompanying Lecture # 28, the VTM, VMA and VFA can be calculated using equations Asphalt mixture was prepared in the lab using 4.8% (by the weight of total mixture) of asphalt binder with specific gravity Gb-1.015 and aggregate with Gsb-2.652.
