A pavement engineer is attempting to study the effect of adding polypropylene (PP) to asphalt concrete. The engineer claims that PP can improve the strength of asphalt concrete. Results of indirect tensile strength tests on asphalt concrete samples with and without PP are shown in Table 1. Do you agree with the engineer's claim?

Q1A In a Marshall test, the percentage of asphalt binder by total weight of aggregate is 5.3%. The bulk specifc gravity of aggregate (G)-2.582, the specifc gravity of asphalt binder (G)=1.000, and the density of water 3 (Yw)=1.000 g/cm. If the voids flled with asphalt (VFA) is 70.0% and the effective asphalt binder (Pbe) is 4.0% by total weight of mixture, determine the following properties: a. The absorbed asphalt binder (Pba) b. The bulk specifc gravity of the compacted mixture (Gmb) c. The voids in mineral aggregate (VMA) d. The voids in total mixture (VTM) e. The theoretical maximum specifc gravity of the loose mixture (Gmm) The effective specifc gravity of the aggregate (Gse) ال
Q. 3 a) Distinguish clearly between hot-mix asphalt and warm-mix asphalt. Why is the latter set to become the mix of the future in asphalt pavement works? b) Explain why asphalt concrete samples from the hot-mix plant are taken for compaction in the laboratory during asphalt overlay construction. c) The following data was taken from a laboratory work sheet on the design of asphalt concrete by the Superpave procedure for a selected aggregate structure: Trial Mix 1 %Gmm@Ndegn=96%, Qam=2470kg/m Trial Mix 2 P.=5.0%, Gmb@Nasgn=2.305 Based on the data, determine the following: i. P, of Mix 1 11. VMA of Mix 1 111. Gmm of Mix 2 Take Ga =2.65, G=2.69, for the aggregates and G,=1.02 for the bitumen used.
During construction of the surface layer of asphalt pavement, two samples were taken every day to measure the asphalt content in the mix to ensure that it is within the specification limits. The target value was set at 5.5% with a tolerance of ±0.4%. The asphalt content data shown in Table P1.41 were collected: a. Calculate the mean, standard deviation, and the coefficient of variation of the data. b. Using a spreadsheet program, create a control chart for these data show- ing the target value and the upper and lower specification limits. Are the asphalt content data within the specification limits? Comment on any trend and possible reasons.
