Abstract The shortage of natural aggregates is becoming a severe problem in the pavement industry globally. To address
this issue, in this study, an effort was made to use reclaimed asphalt pavement (RAP) and coal gangue (CG) as
coarse and fine aggregate, respectively for producing the hot mix asphalt (HMA). As the replacement of natural
aggregate, there were seven types of HMA containing 20% and 40% RAP coarse aggregate content, and 10% and
25% CG fine aggregate content were designed and prepared. In addition, Marshall Stability test, rutting resistance
test, immersion Marshall test, freezing-thaw splitting test,… More >
