【摘要】：中国的公路建设发展在建国初期到改革开放这段时期是我国基础建设的黄金时期,尤其在公路建设及运营里程的增加方面取得的举世瞩目的成就。新疆道路交通行业经过几十年的快速发展,公路工程成为发展生产生活的重要的社会基础设施,也是衡量现代社会水平的关键标志。沥青路面使用性能评价能够全面地体现道路的服务水平,通过总结分析路面性能变化数据,建立各项性能数据库,得出新疆地区内的沥青路面衰变趋势,为今后道路建设与养护管理提供指导。本文以沥青路面使用性能为研究重点,利用数据库的建立,整理分析了新疆四种气候分区内的12条典型路段的各项性能指标。采用人工调查的方法与检测车检测相结合的形式进行,仔细调查路面各类病害破损情况,依照公路等级、路基高度、潮湿系数等因素将调查路段分类。同时论述了目前国内外的沥青路面使用性能综合模型和方法,在分析了国内外的预测模型中的不足和优点后,选择了以同济大学的孙立军提出的模型。结合新疆的实际特点,利用实地调查与检测设备采集来的各个单项指标,采用孙立军模型回归分析并提出新疆沥青路面使用性能衰变模型,选取了路基平均高度、交通量和气候因素三个模型参数,揭示在新疆地区自然环境下的沥青路面的使用性能变化规律。并最后用实际情况下了PQI值与预测PQI值进行对比,得出了两者之间的误差较小。但是因时间紧张,资金有限,很多想法都未能付诸实践,期望课题后续研究能够加以完善。
[Abstract]:The development of highway construction in China during the period from the beginning of the founding of the people's Republic of China to the reform and opening up period is the golden period of our country's infrastructure construction, especially in the road construction and the increase of operating mileage, which has attracted worldwide attention. After decades of rapid development of road traffic industry in Xinjiang, highway engineering has become an important social infrastructure for the development of production and life, and also a key symbol to measure the level of modern society. The performance evaluation of asphalt pavement can fully reflect the service level of the road. Through summing up and analyzing the changing data of the pavement performance and establishing various performance databases, the decay trend of the asphalt pavement in Xinjiang is obtained. To provide guidance for future road construction and maintenance management. This paper focuses on the performance of asphalt pavement and analyzes the performance indexes of 12 typical sections in four climatic zones of Xinjiang by the establishment of database. This paper adopts the method of manual investigation combined with the detection of detecting vehicle to investigate the damage of various kinds of pavement diseases carefully. The road sections are classified according to the road grade, the height of roadbed, the moisture coefficient and so on. At the same time, the comprehensive models and methods of asphalt pavement performance at home and abroad are discussed. After analyzing the shortcomings and advantages of the prediction models at home and abroad, the model proposed by Sun Lijun of Tongji University is selected. According to the actual characteristics of Xinjiang, using the individual indexes collected by field investigation and testing equipment, adopting the regression analysis of Sun Lijun model and putting forward the decay model of the performance of Xinjiang asphalt pavement, the average height of roadbed is selected. Three model parameters, traffic volume and climate factors, reveal the changing law of asphalt pavement performance under natural environment in Xinjiang. Finally, the PQI value is compared with the predicted PQI value, and the error between PQI and PQI is smaller. However, due to time constraints and limited funds, many ideas have not been put into practice.
