Gussasphalt has been widely used in steel bridge deck and pavement in China, but it will lead to the pyrolysis aging of gussasphalt binder in the mixing process due to the high temperature and long time mixing. In this paper, the effect of ARA asphalt reclaiming agent on the main performance indexes...
