What is the design bitumen content for this asphalt design mix based on design air voids of 4%? The design bitumen content of air voids at 4% obtained from Figure 1 is determined as 13% How has the asphalt design mix for the wearing course met the minimum VMA threshold of 16? Does the asphalt design mix (with recommended design bitumen content) meet the asphalt mix requirements for the wearing course of medium/heavy traffic category based on Level 1 tests? 1 Rational explanations on unexpected errors in experiments results Bitumen (%) rmax max density of asphalt (t/m3) rbulk bulk density of asphalt (t/m3) rb (den of binder) (t/m3) re (particle den of combined coarse aggregates) (t/m3) rf (particle den of combined fine aggregates) (t/m3) rfill (particle den of filler) (t/m3) ra (bulk den of combined aggregates) b (proportion binder absorbed) (%) Be= (B-b) AV (air voids) % VMA (1) (%) VMA (2) (%) VFB (1) VFB (2) 2.559832886 2.22663932 1.04 2.62 2.5 1.51 2.576350521 2.124838725 1.875161275 13.01622336 17.03094242 17.03094242 23.57308812 23.57308812 5 2.690763052 2.598392384 1.04 2.62 2.5 1.51 2.60347 4.298605939 0.701394061 3.43288005 5.185280998 5.185280998 33.79567952 33.79567952 6 2.728281229 2.116907522 1.04 2.62 2.5 1.51 2.631166489 5.035385949 0.964614051 22.40874953 24.37220985 24.37220985 8.056144023 8.056144023 AV (%) 25 20 15 10 5 O AIR VOIDS (%) vs BITUMEN CONTENT Bitument (%) 5 6 VMA (1) % 30 25 20 15 10 5 0 0 VMA (1) % vs BITUMEN 2 3 Bitumen (%) 5 9 rbulk (t/m3) 3 2.5 2 1.5 1 0.5 0 BULK DENSITY vs BITUMEN 1 2 3 Bitumen (%) 5 9 What is the design bitumen content for this asphalt design mix based on design air voids of 4%?
