【摘要】：交通安全受“人、车、路”三方面因素的影响，随着我国车辆保有量的不断提高，人们对道路的需求从量的需求转变为质的需求，三因素中“路”的因素越来越受到重视。在沥青路面的各个性能当中，路面抗滑抗滑性能与交通安全关系最为密切，路面抗滑性能为交通事故安全提供必要制动力、防滑溜，大大提高行车的舒适性。但是沥青路面抗滑性能与交通事故的关系，沥青路面的安全等级如何去评价，，如何通过调整沥青路面面级配来提高抗滑性能以保证交通安全，还需进一步研究。本论文对河南连霍高速、沪宁高速等高速公路的抗滑数据、交通事故数据进行调查，对调查的数据进行分析，得出沥青路面抗滑性能不同等级与交通事故的的相关性。然后对抗滑数据和交通事故数据进行统计分析，得出湿滑沥青路面交通事故率的预测模型。提出河南省高速公路安全等级评定建议标准，创造性的使用抗滑性能（SFC）和雨天事故率（次/亿车公里）作为评定高速公路安全等级的双重指标，大大降低安全等级评定的误判率。利用累计频率曲线法，对连霍高速公路的的事故多发段进行评定排查，并针对上述事故多发路段和安全等级差的路段提出了整治措施。对沥青路面抗滑衰变规律进行了室外的跟踪调查和室内的模拟研究，得出沥青路面抗滑衰变的一般规律和衰减模型。参照SMA、CMHB的设计思路，利用均匀设计方法对AC-13级配进行优化设计，形成一种“粗碎石之间恰好相互接触”的骨架嵌挤结构的连续级配，从而提高AC-13级配的抗滑性能。
[Abstract]:The traffic safety is influenced by the three factors of "person, car, road". With the continuous improvement of the quantity of vehicle in our country, the demand of road is changed from the demand of quantity to the demand of quality, and the factor of "road" of the three factors is paid more and more attention to.Among the various performances of asphalt pavement, the anti-skid performance of pavement is most closely related to traffic safety. Pavement anti-skid performance provides necessary braking force for traffic accident safety, anti-slippery, and greatly improves driving comfort.However, the relationship between the anti-skid performance of asphalt pavement and traffic accidents, how to evaluate the safety grade of asphalt pavement, and how to improve the anti-skid performance by adjusting the surface grading of asphalt pavement to ensure traffic safety need further study.In this paper, the anti-skid data and traffic accident data of Henan Lianghuo Expressway and Huning Expressway are investigated, and the data of investigation are analyzed, and the correlation between anti-skid performance of asphalt pavement and traffic accident is obtained.Then, the traffic accident rate prediction model of wet slippery asphalt pavement is obtained by statistical analysis of anti-skid data and traffic accident data.This paper puts forward the suggestion standard of highway safety grade evaluation in Henan Province, and creatively uses the anti-skid performance (SFC) and the rainy day accident rate (times / 100 million car kilometers) as the double indexes to evaluate the expressway safety grade.Greatly reduce the rate of miscalculation of safety rating.The accumulative frequency curve method is used to evaluate and check the accident prone sections of Lianghuo Expressway, and the treatment measures are put forward for the above accident prone sections and the sections with poor safety grade.The general law and attenuation model of anti-skid decay of asphalt pavement are obtained through outdoor tracking investigation and indoor simulation study on the law of anti-slide decay of asphalt pavement.According to the design idea of SMA-CMHB, the AC-13 gradation is optimized by using the uniform design method, which forms a continuous gradation of skeleton embossed structure with "coarse-gravel contacting each other" so as to improve the skid resistance of AC-13 gradation.
