新型SBS改性沥青混合料的压实性能研究

随着我国公路事业的发展,高速公路里程迅速增长,尤其是沥青路面的应用更为广泛,但交通量不断增大、车辆轴载不断加重、高速公路的渠化交通等不利因素,也对沥青路面的使用性能和抗疲劳能力提出了更高的要求。新型SBS改性沥青在高等级公路,城市干道和机场跑道等方面有着广泛的应用,大量实践证明,可以显著提高路面的使用性能,延长路面的使用寿命,降低养护维修费用。本文通过对SBS沥青及SBS沥青混合料各方面性能的研究,旨在了解SBS改性沥青的基本性质作用,以及其在工程中的应用与适用性,为今后使用SBS改性沥青提供方便。

Research on Compaction Performance of New SBS Modified Asphalt Mixture

With the development of Chinese highway industry,highway mileage is rapidly growing,especially more wide application of the asphalt pavement,but negative factors such as increasing volume of traffic,aggravating axle load,canalized traffic of expressway,also put forward higher requirements to using performance and anti-fatigue capability of asphalt pavement.It has wide application of new SBS modified asphalt in high grade highway,urban trunk road and airport runways.Lots of practice proves that it can improve the using performance of pavement and extend the service life of the road,reduce maintenance costs.Through the research on the various performance of SBS asphalt and SBS asphalt mixture,this article aims to understand basic properties of the function of SBS modified asphalt as well as its application and applicability in engineering,so as to provide convenient to using SBS modified asphalt in future.
