Comparative Study on Anti-Skid Performance Testing Methods for Asphalt Pavements

摘要:

沥青路面的抗滑性能直接影响道路的行车安全，为选择合适的抗滑性能检测方法获取真实的路面状况，为制定有效的养护措施提供更全面的决策依据，针对沥青路面的抗滑性能检测方法开展了对比研究。主要选取并比较了激光构造深度、摆式仪测摆值、横向力系数测摩擦系数等常用检测方法。研究结果表明，不同方法在测量原理、检测精度、检测结果和检测效率等方面存在显著差异。为提高检测的准确性，需综合考虑路面状况、环境条件和检测设备性能等因素，必要时可采用两种或两种以上方法相结合的方式。

Abstract:

The skid resistance of asphalt pavement directly impacts the driving safety of roads. To select the appropriate skid resistance testing methods for obtaining the accurate pavement conditions, and to provide a more comprehensive decision-making basis for formulating effective maintenance measures, a comparative study is conducted on the skid resistance testing methods of asphalt pavement. The commonly used testing methods such as laser texture depth, pendulum value measurement by pendulum instrument, and friction coefficient measurement by lateral force coefficient are primarily selected and compared. The study result reveals the significant differences among the different methods in terms of measurement principles, testing accuracy, testing results and testing efficiency. To enhance the testing accuracy, it is necessary to comprehensively consider the factors such as pavement conditions, environmental conditions and testing equipment performances. When necessary, a combination of two or more methods can be adopted.
