The invention belongs to the technical field of bituminous road construction scheme decision making, and particularly relates to a multi-target optimization method for bituminous road in-place hot recycling construction schemes. According to the method, a bituminous road paving discrete event model is constructed by applying discrete event simulation software EZStrobe; visualized simulation of twoconstruction processes such as a remixing regeneration method and a remixing overlaying method is realized; a construction scheme multi-target optimization model which takes construction environmentinfluences, construction cost and construction quality as decision variables is constructed; and a multi-target optimization problem is solved through an NSGA-II algorithm so as to obtain a Pareto optimum solution. According to the method, the established construction scheme multi-target optimization model which takes the construction environment influences, the construction cost and the construction quality as decision variables is solved to carry out comprehensive quantitative assessment on economic benefit, environment benefit and road performance of bituminous road in-place hot recycling construction schemes. According to the method, multi-target optimization is carried out on construction schemes of bituminous roads, so that a decision optimization method for the bituminous road in-place hot recycling construction schemes is provided.
Description
technical field [0001] The invention belongs to the technical field of asphalt pavement construction scheme decision-making, and in particular relates to a multi-objective optimization method for an in-situ heat regeneration construction scheme of asphalt pavement. Background technique [0002] At present, road workers have proposed three basic in-situ thermal regeneration construction schemes for asphalt pavement according to different road diseases, namely, surface regeneration method, resurfacing regeneration method and remixing regeneration method. In the decision-making process of the construction plan, the decision-maker requires that the construction quality standard project tasks be completed at a reasonable construction cost within the specified construction period. However, the relationship among environmental impact, cost and quality is intricate, and it is difficult to achieve the optimal effect at the same time. [0003] In terms of environmental impact, resear...
