Method for determining influence factors of mineral aggregate grading macrostructure depth
The invention discloses a method for determining influence factors of mineral aggregate gradation macrostructure depth, which comprises the following steps of: firstly, determining the influence of particle size on the macrostructure depth, and then determining the influence of compaction work on the mineral aggregate macrostructure depth; and finally, determining the influence of the repeated load on the macrostructure depth of the mineral aggregate. According to the method provided by the invention, the macrostructure depth of mineral aggregate gradation can be determined, so that theoretical reference is provided for mineral aggregate gradation design, and the problem that the requirement of driving safety cannot be met due to the fact that the anti-skid performance is not considered inasphalt mixture design, so that the anti-skid capacity is attenuated too fast after a road surface is built is avoided.
本发明公开了一种矿料级配宏观构造深度影响因素的确定方法，首先确定粒径对宏观构造深度的影响，再确定压实功对矿料宏观构造深度影响；最后确定重复荷载对矿料宏观构造深度的影响。通过本发明提供的方法可以确定矿料级配的宏观构造深度，从而为矿料级配设计提供理论参考，避免在沥青混合料设计中没有考虑抗滑性能而导致路面建成后抗滑能力衰减太快，无法满足行驶安全性的需要。
