Research on the Performance of Smoke Suppressing Asphalt and Asphalt Mixtures
In the context of carbon peaking and carbon neutrality,smoke suppression asphalt and its performance evaluation have become a research hotspot in the road infrastructure industry.Two types of smoke suppressants were selected to design several sets of different dosages,and the smoke sup-pression effect was evaluated through preliminary experiments such as UV spectrophotometry.The influence of smoke suppressants on the physical properties,rheological properties,aging properties,and storage stability of asphalt was analyzed.Furthermore,the high temperature performance,low temperature performance,and water stability performance of asphalt mixtures were further studied.Taking into account the smoke suppression effect,asphalt performance,and asphalt mixture perform-ance,the optimal dosage of smoke suppressant A is determined to be 0.3%,and the optimal dosage of smoke suppressant B is determined to be 1%.This provides a reference for the practical application of new environmentally friendly smoke suppressant asphalt in the future.
