Research on the structure and technology of anti-cracking low noise cape seal
Because the cape seal has outstanding advantages,there are many applications in my country's highway construction and maintenance,but there are also some shortcomings,which limits its applications on high-level highways,especially highways.Only by replenishing the strengths can we better serve engineering practice.Through comparative studies,the cape seal has the following shortcomings:the crack resistance performance of is not outstanding,driving noise is large,and the serious dependence on the high temperature and sunny weather.Using asphalt fiber seal to improve crack resistance,using waste tire rubber powder micro-surfacing treatment to reduce driving noise,and using vacuum water absorption technology to reduce the dependence of construction on high temperature and sunny weather.These technologies can make up for the shortcomings of the cape seal,and the pavement performance has been comprehensively improved.The cape seal becomes an ideal surface treatment structure layer and its applications are more and more and widespread.The amount of fiber should be 80～160g/m2;the oil stone ratio should not be less than 8.5%;the appropriate ratio of waste tire rubber powder to asphalt is 10%～25%.
