Asphalt superpave - naming Example5. Calculate amounts and standard deviations using data from all samples of the same mix design. Compare average results from different design mixes. Do the samples fall within PennDOTs acceptance criteria?The laboratory experiment was happy since the results showed that the samples prepared had compacted air voids of between 3% and 8%. For C, the percent covered by air voids was 3.22% art object for D the percent was 2.95%. This range prevents the possibility of the voids becoming interconnected thereby reducing the susceptibility of the pavement undergoing permeation by air and moisture. The percent of water absorbed for both specimen C and D was less than 3 percent consequently there was no need for paraffin-coated. The samples fall within PennDOTs acceptance criteria because they have percent of air voids around 4% and 96% compaction. However, C proves to be the stovepipe sample since its values for percent air voids (3.22) and compaction ( 96.78%) are closer to PennDOTs acceptance criteria. This marrow that design mixes C and D are suitable for asphalt pavement since they give assurance on the required degree of compaction and percent air voids in compacted bituminous
