A STUDY ON ADDICTIVES FOR FUME REDUCTION IN ASPHALT PAVEMENT CONSTRUCTION
In the construction process, asphalt pavement will generate a lot of asphalt fumes, which contain a large number of toxic and hazardous substances that will produce injury to the construction workers and residence around. In order to radically reduce asphalt fumes in the construction process, through self-designed test equipment, we added SBS (Styrene Butadiene Styrene), melamine and activated carbon which may have fumes suppression effect to the asphalt and experimented, obtained: (1) SBS which had fumes suppression effect, could be used as an additive to reduce asphalt fumes; (2) Melamine and activated carbon, which would produced a number of side effects, could not be used as an additive to reduce asphalt fume. At present the research of modified asphalt which produces lower fumes is basically still in a blank state, but the paper will fill the gaps in this aspect and provide a test device and method to study on modified asphalt with low fumes.
