【摘要】：随着我国经济的快速发展和持续增长，我国的公路建设也进入了前所未有的大发展时期。公路运输事业也向着大吨位、高速度的方向发展。然而以半刚性基层为首选基层的公路项目，却逐渐暴露出一些严重的缺陷。高速公路项目建设一次性投资大，特别是高速公路沥青路面造价高昂，因此寻求有效的解决途径来避免或减少公路半刚性基层的裂缝缺陷，并运用正确的成本分析方法对其进行经济分析，已成为高速公路建设项目稳步发展的重要环节。本文通过对玄武岩纤维半刚性基层的试验数据的统计和分析，从技术上阐述了玄武岩纤维在公路半刚性基层的可行性以及使用中的理论最佳掺量。对半刚性基层在柔性路面体系的应用及性能进行了分析，详细阐述了黄骅港南疏浚港东延伸项目各路面方案，并根据国内外路面使用性能周期研究成果和衰变模型选出适合黄骅港南疏浚港东延伸项目的预测模型，预测出不同方案下黄骅港南疏浚港东延伸项目公路路面使用性能的衰变规律和性能周期，为路面全寿命周期成本分析奠定基础。通过运用全寿命周期成本分析理论，结合国内外对于公路全寿命周期理论的研究成果，建立了高速公路全寿命周期成本计算模型，，进而应用此模型对黄骅港南疏浚港东延伸项目建设方案进行经济分析。得到最终的结论：玄武岩纤维半刚性基层并未使得建设期投入成本增加，而且因为性能的提高降低了后期运营期内养护成本和车辆运营成本。综合考虑整个寿命周期，玄武岩纤维半刚性基层路面的成本最低，具有良好的经济性，推荐使用这种建设方案。综上，本文在借鉴国内外已有的理论框架和工程实践的基础上，将全寿命周期成本理论应用于减少路面裂缝发生的玄武岩纤维半刚性基层路面的经济分析上，全面考虑项目建造期、运营期直至报废的全过程成本，对于形成一种追求项目一生所耗成本最小，使用效益最大的氛围有利。
[Abstract]:With the rapid development and sustained growth of China's economy, China's highway construction has entered an unprecedented period of great development. Highway transportation also develops towards large tonnage and high speed. However, the highway project with semi-rigid base as the first choice gradually exposed some serious defects. Expressway project construction one-time investment is big, especially the highway asphalt pavement cost is high, therefore seeks the effective solution way to avoid or reduce the highway semi-rigid base course crack flaw, Using the correct cost analysis method to analyze its economy has become an important link in the steady development of highway construction project. Based on the statistics and analysis of the experimental data of basalt fiber semi-rigid base, the feasibility of basalt fiber in highway semi-rigid base and the optimum theoretical content in use are expounded in this paper. The application and performance of semi-rigid base course in flexible pavement system are analyzed, and the pavement schemes of the East extension Project of South dredged Port of Huanghua Port are described in detail. According to the research results of pavement performance cycle and decay model at home and abroad, the prediction model suitable for the East extension Project of South dredged Port of Huanghua Port is selected. The decay law and performance cycle of pavement performance of the East extension Project of South dredged Port of Huanghua Port under different schemes are predicted, which lays a foundation for the cost analysis of pavement life cycle. By applying the theory of life-cycle cost analysis and combining the research results of highway life-cycle theory at home and abroad, the calculation model of freeway life-cycle cost is established. Then the model is used to analyze the construction scheme of the East extension Project of South dredged Port in Huanghua Port. The final conclusion is that basalt fiber semi-rigid base does not increase the input cost in the construction period and the maintenance cost and the vehicle operation cost are reduced because of the improvement of the performance. Considering the whole life cycle, basalt fiber semi-rigid base pavement has the lowest cost and good economy. In summary, based on the existing theoretical framework and engineering practice at home and abroad, this paper applies the life-cycle cost theory to the economic analysis of basalt fiber semi-rigid base pavement which reduces the occurrence of pavement cracks. The overall consideration of the whole process cost of the project construction period, operation period and scrapping is beneficial to the formation of a kind of atmosphere in which the cost of pursuing the project is the least and the use benefit is the greatest.
