Self-adhering polymer modified asphalt waterproof membranes were prepared by different types of softening oil.The effects of chemical composition of softening oil on the high and low-temperature performance,tack,peel strength,thermal aging and water resistance of self-adhering waterproof membrane were investigated.The results showed that the saturates of softening oil were highly correlated with the high and low-temperature performance of self-adhering waterproof membrane,and the self-adhering waterproofing membrane prepared by softening oil with high saturates content had better anti-thermal aging properties and low-temperature flexibility.The polar components(aromatics and resins)of softened oil were strongly related to the tack,peel strength,thermal aging,and water resistance of self-adhering waterproof membranes.Self-adhering waterproof membranes prepared from softened oils with high content of polar components have higher adhesion and peel strength as well as better anti-thermal aging property and water resistance.
