Structure long-term preservation and maintenance method suitable for semi-rigid base asphalt pavement
The embodiment of the invention discloses a structure long-term preservation and maintenance method suitable for a semi-rigid base asphalt pavement, which comprises the following steps: when the evaluation of the overall condition of the pavement meets the standard and the evaluation of the base stability is stable, performing surface layer stability evaluation by adopting a surface layer decision tree model; and if the stability of the surface layer is evaluated to be unstable, carrying out structure preservation and maintenance on the pavement. The method has the following advantages: (1) the long-term preservation definition and technical measures of the asphalt pavement structure are put forward for the first time, and the goal of long-term preservation of the pavement structure is clarified, that is, through periodic surface maintenance and overlay and structure reinforcement, deterioration of the interior and the base layer of the pavement is slowed down, structural overhaul and reconstruction are avoided, and the pavement structure performance is kept stable for a long time; the service life of the pavement is prolonged. And (2) a decision-making tree model is established by combining the requirements of preventive maintenance of the road surface and long-term storage of the structure, the decision-making tree model comprises a preventive maintenance decision-making module, a structure storage decision-making module and a structural overhaul decision-making module, and the structural problem in expressway maintenance can be solved.
本发明实施例公开了一种适用于半刚性基层沥青路面的结构长期保存养护方法，包括：当路面整体状况的评估满足标准且基层稳定性的评估为稳定时，采用面层决策树模型进行面层稳定性评估；若面层稳定性评估为不稳定，则对路面进行结构保存养护。本发明优点如下：(1)首次提出沥青路面结构长期保存定义和技术措施，明确了路面结构长期保存的目标，即通过周期性的表层维修、罩面和结构补强，减缓路面内部和基层的劣化，避免结构性的大修和重建，保持路面结构性能长期稳定，延长路面的使用寿命。(2)结合路面预防性养护和结构长期保存需求，建立决策树模型，包括预防性养护、结构保存、结构性大修三个决策模块，可解决高速公路养护中的结构性问题。
