【摘要】：随着我国国省干线公路建设的发展，公路网规模不断扩大，山区交通日益便利，，但是随着大量山区干线公路使用年限的增长，其路用使用性能却日渐下降，公路沥青路面养护问题越来越受到普遍关注。为保持路面良好的使用状态，减少早期病害的发生，延缓病害的发展，延长路面使用寿命，降低养护成本，选择合适的预养护技术对山区干线沥青路面进行预防性养护，对于公路自身和山区社会经济的发展均具有重要意义。 山区干线公路养护在带来诸多正面效应的同时，也给生态环境带来了不同程度的负面效应，因此选择一种可以弱化负面效应，与生态环境相协调，具有可持续发展前景，绿色效应客观的预养护技术已成为必然趋势。 基于此，本文在沥青路面就地热再生技术已有研究成果的基础上，对山区干线公路就地热再生技术绿色效应进行研究，为我国山区干线公路预养护技术的选择提供一些理论研究依据。 本文在绿色施工评价体系的基础上探讨绿色预养护评价体系，借鉴可持续发展指标体系的压力-状态-响应模型，建立了山区干线公路就地热再生绿色评价研究的PSR框架模型，明确指标体系的各个指标，并用层次分析法计算各指标权重，运用灰色系统综合评价方法建立山区干线公路就地热再生绿色评价模型，最后运用该评价模型对贵州省省道S201(K135+000~K163+000)玉铜线沥青路面就地热再生项目进行综合评价，证明其实用性。 研究结果表明，沥青路面就地热再生技术具有较好的绿色效应，施工中废气排放量少、噪声小，对环境污染小；可充分利用旧沥青路面混合料，节约原材料，降低施工成本，实现资源的再生循环利用；施工过程中占用工作面小，不中断交通，施工作业时间短，对公共交通的影响小。
[Abstract]:With the development of national and provincial trunk road construction, the scale of highway network is expanding and the traffic in mountainous area is more convenient. However, with the increase of service life of a large number of mountain trunk roads, the performance of road use is declining day by day. More and more attention has been paid to the maintenance of highway asphalt pavement. In order to maintain the good condition of pavement use, reduce the occurrence of early diseases, delay the development of diseases, prolong the service life of pavement, reduce the maintenance cost, and select appropriate pre-maintenance technology to carry out preventive maintenance of asphalt pavement in mountain trunk line. For the highway itself and the development of social and economic mountain areas are of great significance. The mountain trunk highway maintenance brings many positive effects, but also brings different negative effects to the ecological environment. Therefore, choosing one that can weaken the negative effect, coordinate with the ecological environment, has the prospect of sustainable development. Green effect objective pre-curing technology has become an inevitable trend. Based on this, the green effect of geothermal regeneration technology on mountain trunk highway is studied in this paper, based on the existing research results on geothermal regeneration technology of asphalt pavement. It provides some theoretical basis for the selection of pre-maintenance technology of mountain trunk highway in our country. Based on the evaluation system of green construction, this paper probes into the evaluation system of green pre-maintenance. Using the pressure-state-response model of the index system of sustainable development, the PSR framework model for the green evaluation of geothermal regeneration of mountain trunk roads is established. Every index of the index system is defined, the weight of each index is calculated by AHP, and the green evaluation model for geothermal regeneration of mountain trunk highway is established by using the comprehensive evaluation method of grey system. Finally, the evaluation model is used to evaluate the geothermal regeneration project on the asphalt pavement of Jade Copper Line of Guizhou Provincial Highway S201 (K135 000~K163 000), which proves its practicability. The results show that bituminous pavement has good green effect, less exhaust gas emission, less noise and less pollution to the environment. It can make full use of the old asphalt pavement mixture, save the raw materials, reduce the construction cost, realize the recycling utilization of the resources, occupy the working face small in the construction process, do not interrupt the traffic, the construction operation time is short, the influence to the public transportation is small.
