POLYMER MODIFIED BITUMENT WATERPROOF MEMBRANE FOR RAILWAY&BRIDGE
- Implementation standards：
1.With the design of “bias-base” and double side fine sand,the bonding problem between different layers of pavement is well solved;
2.Can be strongly bonding with concrete,no bubble caused,good water permeability;
3.The membrance has a strong tensile strength in vertical or horizontal direction,high elongation rate,good resistance to high temperature,anti-rabbing breaking ability to with stand repeated grind&puncture of equipment in the prime construction period,and also well withstand the repeated action of the car driving.
4.Endurable at cold environment,resistance to alkali and salt,rreezing thawing action,anti aging and anti fatigue,anti crack deformation ability etc;
5.The construction performence is good,adpot hot melt method construction,the operation is convenient,save time,can effectively ensure the normal survice life of railway bridge.
