The influence factors on high temperature storage stability of crumb rubber modified asphalt were analyzed. The methods of improving the high temperature storage stability were reviewed based on formula and process at home and abroad. The developing prospects of the modified asphalt were forecasted. It could be concluded that improving the high temperature storage stability was a criterion for industrialization and stable application of asphalt modified with crumb rubber. |
