现如今,SMA沥青混合料是一种黏度较高的改性沥青混合料,其在摊铺之后有降温的作用,这样就很难被压实,尤其是两边端部50cm之内混合料因为摊铺机以及离析等因素,导致其很难被压实,最终引发水损害情况的发生。其优势主要体现在:抗渗性、耐久性、抗滑、抗裂、抗车辙等等,其被大范围的应用在高等级公路路面的具体施工之中。因为其具备良好的使用性能,因此也受到了很大的专注度,国内的学者这对SMA相应的进行了深入的研究与探讨。鉴于此,本文主要针对SMA路面施工胶轮+钢轮组合碾压施工来进行分析与阐述。
Now, SMA asphalt mixture is a high viscosity modified asphalt mixture, which has the effect of cooling after paving, so it is difficult to be compacted, especially for the mixture within 50cm at both ends Pavements and segregation and other factors, leading to its very difficult to be compacted, eventually lead to water damage occurred. Its advantages are mainly reflected in: impermeability, durability, anti-skidding, cracking resistance, anti-rutting, etc., which are widely used in the construction of high-grade highway pavement. Because of its good use of performance, it has also been a great deal of attention, the domestic scholars on the corresponding SMA conducted in-depth research and discussion. In view of this, this article mainly for SMA pavement construction rubber wheel + steel roller compaction construction to analyze and elaborate.
