【摘要】：路面的抗滑性能是影响交通安全的重要因素，如何控制路面抗滑性能的衰变是众多研究人员所关注的问题。而路面宏观纹理磨损是沥青路面抗滑性能衰变的重要原因，因此对沥青路面抗滑性能衰变与路面宏观纹理磨损之间关系的研究显得十分重要。本研究在不同等级、不同类型的沥青路面上选取了多个测点，从道路建成初期开始，对路面宏观纹理和抗滑性能进行了历时2年多的跟踪测试。其中，路面宏观纹理特征测试采用铺砂法和三维扫描测试法，两种方法，，路面抗滑性能的测试采用动态摩擦系数测试仪（DFT）来测定路面的摩擦系数。通过对不同种类，多个宏观纹理指标随通车时间变化趋势的分析，选取了衰变规律较明显的一些纹理指标，利用这些指标的变化规律来描述沥青路面宏观纹理的磨损规律。对于路面抗滑性能衰变的研究，选取了多个抗滑性能指标,并分析了这些抗滑性能指标随通车时间的衰变趋势，并利用SPSS软件尝试建立了抗滑性能指标随通车时间的衰变模型，以此来描述路面抗滑性能随通车时间的衰变规律。最终，对路面宏观纹理指标与抗滑性能指标的协同衰变路径进行了分析,利用SPSS软件尝试建立了抗滑性能指标与宏观纹理指标的协同衰变模型，以此对路面抗滑性能随宏观纹理磨损的衰变规律进行描述。本研究对进一步研究沥青路面抗滑性能随路面宏观纹理磨损的衰变规律提供了一定的基础,对沥青路面抗滑性能衰变的控制具有一定的借鉴意义。
[Abstract]:The anti skid performance of the pavement is an important factor affecting the traffic safety. How to control the decay of the pavement skid resistance is the concern of many researchers. And the pavement macro texture wear is an important reason for the decay of the anti skid performance of the asphalt pavement, so the relationship between the anti skid performance of the asphalt pavement and the macroscopic texture wear of the pavement is studied. It is very important to study.
In this study, several testing points were selected on different grades and different types of asphalt pavement. From the beginning of the construction of the road, the macro texture and anti skid performance of the pavement were tested for more than 2 years. Among them, the pavement macro texture features were tested by sand laying and three-dimensional scanning, and two methods were used to test the anti skid performance of the pavement. The dynamic friction coefficient tester (DFT) is used to determine the friction coefficient of the pavement. Through the analysis of the changing trend of different kinds of macro texture index with the changing trend of the traffic time, some texture indexes which are more obvious in the decay law are selected. The law of the change of these indexes is used to describe the wear law of the macroscopic texture of the asphalt pavement. Several anti slip performance indexes are selected, and the decay trend of these anti skid performance indexes with traffic time is analyzed, and the decay model of anti skid performance index with traffic time is established by using SPSS software. In order to describe the decay law of pavement anti skid performance with the traffic time. The cooperative decay path of the index and the anti skid performance index is analyzed. A cooperative decay model of the anti skid performance index and the macroscopic texture index is tried to be established by using the SPSS software, and the decay law of the anti skid performance of the pavement with the macroscopic texture wear is described.
This study provides a certain basis for further research on the decay law of the asphalt pavement's anti sliding performance with the pavement macro texture wear, and has a certain reference for the control of the decay of the anti skid performance of the asphalt pavement.
