A large amount of asphalt smoke is released from the asphalt pavement during the building process. The smoke
not only causes discomfort to the workers and reduces the construction efficiency, but also causes serious environmental
pollution. In order to reduce the emission of toxic gases generated during the construction of asphalt pavement, the smoke
#
suppressant was added into 70 base asphalt, so as to prepare smoke suppression asphalt, and the performance of smoke

method of alone mixing or compounding on the smoke suppresseion effect of asphalt were researc
