 Temperature tar in distillation residue is part of the asphalt, tar yield accounted for 54 to 56%, which is more than three-ring aromatic compounds and oxygen, nitrogen, sulfur-containing heterocyclic compounds and a small amount of polymer material composed of carbon. The molecular weight of the asphalt components between 200 to 2000, up to 3000. The softening point temperature is based on a different pitch division. Softening point of 65 ~ 90 ℃ in temperature for the asphalt.
