【摘要】：随着我国经济的高速发展以及高速公路建设期的逐渐缓慢,我国汽车保有量稳步增加,且重载交通呈现越来越高的趋势,给已建成高速公路带来巨大压力,高速公路沥青路面不可避免地出现了各类病害。因此必须及时采取合理的措施,处理道路出现的各种病害,使道路保持较高的服务能力,在预处理达不到预期目标时,路面大修技术就显得尤为重要。本文首先针对目前山区高速公路沥青路面常见病害进行了分类及调查,包括不同病害类型、气候条件、交通调查,并分析了其病害原因;针对不同路面病害,研究根据国内外病害处治技术进行了统筹,从裂缝、水损害、车辙、沉陷等病害出发,提出了预防及相应处治措施。其次,结合病害调查及路面处置技术,研究以长寿至太平段沥青路面大修工程为依托,从路面大修设计总方案、路面加铺方案、微表处方案、路面病害局部翻修设计、旧沥青换合理再生利用、桥面防水粘结层、防反材料及过渡段设置等方面提出了长寿至太平段沥青路面改善方案。最后,进行了长寿至太平段沥青路面大修配合比试验,从微表处、防水粘结层、玻璃纤维强封层、碎石及再生沥青混合料提出了沥青路面改善试验设计及技术指标,其中玻璃纤维强封层设计为本次大修设计方案的亮点及创新。通过本次研究提出的长梁高速公路沥青路面病害改善技术及大修方案,为高速公路沥青路面养护工作达到规范化、科学化和高效化的要求提供技术支撑,进而有助于提高高速公路的使用性能和使用年限。
[Abstract]:With the rapid development of our country's economy and the gradual slow construction period of expressway, the number of vehicles in our country is increasing steadily, and the heavy haul traffic is becoming more and more high, which brings great pressure to the highway that has been built. Various kinds of diseases inevitably appear on the asphalt pavement of expressway. Therefore, it is necessary to take reasonable measures in time to deal with all kinds of road diseases, so that the road can maintain a high service capacity. When the pretreatment fails to reach the expected goal, the pavement overhaul technology is particularly important. In this paper, the common diseases of asphalt pavement in mountain expressway are classified and investigated, including different disease types, climate conditions, traffic investigation, and the causes of the disease. According to the treatment technology of diseases at home and abroad, the prevention and treatment measures are put forward from cracks, water damage, rutting, subsidence and other diseases. Secondly, combined with disease investigation and pavement disposal technology, this paper studies the design of pavement overhaul design, pavement overlay scheme, micro-surfacing scheme, local repair design of pavement disease, based on the major repair project of asphalt pavement in Longshou to Taiping section. The improvement scheme of asphalt pavement in long-life to Taiping section is put forward in the aspects of reasonable regeneration of old asphalt, waterproof and adhesive layer of bridge deck, anti-reaction material and setting of transition section. Finally, the proportion test of asphalt pavement overhauling from longevity to peace is carried out. From the micro-surface, waterproof adhesive layer, glass fiber strong sealing layer, crushed stone and recycled asphalt mixture, the improvement test design and technical index of asphalt pavement are put forward. One of the glass fiber strong seal design for this overhaul design plan bright spot and innovation. Through the improvement technology and overhaul scheme of asphalt pavement in Changliang Expressway, the technical support is provided for the standardization, scientific and high efficiency of highway asphalt pavement maintenance. Furthermore, it is helpful to improve the performance and service life of expressway.
