Data for: Long-Term Skid Resistance of Asphalt Surfacings and Aggregates’ Mineralogical Composition: Generalisation to Pavements made of Different Aggregate Types

The raw data here are used to calculate the AHPM (“Averaged Aggregate Hardness Parameter”) parameters of pavement surfaces and to determine their capacity of skid resistance in the long term. They are composed by : • the type of aggregates and their proportions by volume in each pavement, • the calculated of the Aggregate Hardness Parameter (AHP) and • the determined AHP of each of the pavements. After the calculation of this parameter and with the help of analytical functions that we recall below, the skid Resistance capacity of that asphalt su, facing in the long term will be deduced. This long-term skid resistance value corresponds to that determined in the test with the Wehner Shulz machine.本数据集的原始数据用于计算路面表面的集料平均硬度参数（Averaged Aggregate Hardness Parameter，AHPM），并测定其长期抗滑性能。数据集内容包含： • 各路面所用集料的类型及其体积占比； • 集料硬度参数（Aggregate Hardness Parameter，AHP）的计算值； • 各路面的实测AHP值。 在完成该参数的计算后，结合下文提及的解析函数，即可推导出该沥青路面的长期抗滑性能。该长期抗滑性能数值与韦纳-舒尔茨（Wehner Shulz）试验机测试所得结果一致。
