Abstract


A significant decrease in the rate of thermal-oxidative processes occurring in bitumen and directly in a thin film on the surface of mineral materials for preparing warm asphalt concrete has been determined. This is due not only to decrease of the temperature of the bitumen and bituminous mixture, but also to the inhibitory effect of temperature-reducing additives. In turn, the decrease in the intensity of warm asphalt concrete aging during the preparation, transport and laying will positively influence the increase of pavement life.
