Research on Temperature Sensitivity of Modified Bitumen and Self-adhesive SBS Modified Bitumen Waterproofing Membrane
In this article,the temperature sensitivity of modified bitumen and self-adhesive SBS modified bitumen waterproofing membrane is studied.The bitumen and self-adhesive SBS modified bitumen waterproofing membrane prepared by simulated formula is tested,and data such as penetration index,softening point and low temperature flexibility are obtained.Based on the evaluation,the correlation between raw material bitumen and the finished waterproofing membrane is analyzed.The results show that both the temperature sensitivity and the resistance to temperature change of modified bitumen can be used to evaluate the self-adhesive polymer modified bitumen waterproofing membrane.
