日益增长的经济建设对道路交通提出了越来越高的要求,围绕减少道路病害,提高道路寿命的研究为世界各国所重视。沥青路面的设计大修期为15年,而目前我国的沥青路面往往8年~10年就需要进行检修。以路面寿命30年计,资料表明这期间用于道路的维修费用几乎等于新建道路的投资。可见提高公路寿命,延缓检修期至关重要。影响公路质量重要的因素之一是路面损伤,其中最突出的表现为路面裂缝。本文通过沥青砼加强纤维,SBS改性沥青讨论沥青裂缝的防治方
The ever-increasing economic construction has put forward higher and higher requirements on road traffic. The focus on reducing the number of road diseases and increasing the road life is emphasized by all the countries in the world. Asphalt pavement design overhaul period of 15 years, while the current asphalt pavement in China often 8 years to 10 years on the need for maintenance. Based on the 30-year pavement life expectancy, the data show that the maintenance costs for roads during this period are almost equal to the investment in new roads. Can be seen to improve road life, delay maintenance period is essential. One of the most important factors affecting the quality of the road is the road damage, the most prominent of which is the crack in the road surface. In this paper, reinforced asphalt concrete, SBS modified asphalt to discuss the prevention and treatment of asphalt cracks
