Resumo: | This paper reports the influence of the percentage of recycled aggregate (RCA) fromconstruction and demolition waste (C&DW) together with the percentage of binder (L), curing time(t) and temperature (T) of the samples on the stiffness of a hot asphalt mixture. The study was carriedout using the response surface methodology (RSM). The resilient modulus was chosen to estimate thestiffness of the mixture. The percentages of RCA studied were 0% (control), 5%, 10%, 20% and 30%,whilst 3.5%, 4% and 4.5% were those chosen for the binder content. Before compacting the samples,they were left into the oven to cure. Curing time, or pretreatment time, were set at 0 (control), 2 and4 h. The samples were subjected to temperatures of 0, 10 and 20◦C. The natural aggregate is of thehornfels type. All the specimens studied showed high stiffness at low temperatures. According tothis research, temperature proved to be the most influential factor on the decrease in the resilientmodulus and, conversely, the percentage of recycled aggregate is not a significant factor in the rangeof values studied. |
