ABSTRACT

Total suspended particulate (TSP) emissions from asphalt mixing station can bring about a dramatic negative impact on the environment. In this paper, TSP emission characteristics during the production process at the asphalt mixing station were quantitatively analyzed based on the type of the production equipment and the mixture production process. Prevention and control measures against TSP emissions were proposed accordingly. The analysis showed that cold feed bins were the largest source of TSP emissions among all production equipment under monitoring. The highest TSP emission occurred in stone mastic asphalt (SMA) production. Combination prevention and control measures were found to be most effective among all anti-dust measures, reducing TSP emission by over 60%.
