Tunnel Safe Enbironment Mixture In Tunnel Application

In present,the tunnel road mostly uses the cement concrete pavement form, however,the asphalt pavement smoothness with high traffic and comfortable,wearable, and the advantage of anti-sliding,noise reduction and short construction period.So asphalt pavement is more and more used in the highway, the flooring and the road tunnel. As regard to the tunnel road surface's environment characteristic and the pavement's special performance requests, this article has developed one kind of security environmental protection asphalt mixture which enables the asphalt pavement not only display own performance superiority, but also satisfy the tunnel security, the noise reduction, anti-slides need. This article mainly develops a kind of modifying asphalt which has the collection of anti-slide,noise reduction,fire-retarding and high viscosity in body,then carries on the mixture design and makes the research to this kind of blend's special performance. The result indicates that this mixture not only may display its fine performance completely, moreover may make the function more perfect according to the tunnel road surface's special request. The research technique and the method used in this article is mainly through the experimental study. Through the tentative data we can analysis security environmental protection noise reduction asphalt mixture's superiority.
