【摘要】：随着沥青路面越来越广泛的应用,其普遍出现的道路病害的问题逐步引起相关部门的重视,如何合理、有效的进行沥青路面的预防性养护已成为沥青路面设计必须考虑的问题。沥青纤维碎石封层技术可有效改善沥青路面的道路病害问题。目前,该技术在国外已取得了较多的工程经验,但在国内仍鲜有应用。相关设计经验依旧欠缺,在实际的工程应用中存在极大的盲目性和随意性。本文依托浙江省G320道路路面养护的工程实例,调查了G320省道路面病害及周边的气候情况；分析了路面的主要病害,并就病害产生原因进行了分析；提出了针对性的路面病害处理办法。通过全路面统一加铺1cm纤维沥青碎石封层的预防性养护病害处置,改善了行车条件,延长了路面使用寿命。根据后续的跟踪调查：使用沥青纤维碎石封层预防性养护技术后,路面的使用效果较好,行车环境得到了极大改善了；该技术阻断了雨水下渗对路面结构的破坏,减缓路面裂缝的出现周期,延长了路面的使用寿命。并且,调查发现：随着时间推移,沥青纤维碎石封层的泛油和脱粒均有出现,且逐步发展为脱皮,除了施工质量管理外,仍需对该技术材料选择、材料用量确定、施工工艺优化等进行更深入的研究。综上所述,通过该项目设计及后续的跟踪评估,提出了沥青纤维碎石封层技术的沥青纤维碎石封层建议用量及对施工合理化建议。另外,该应用研究,可为类似地理环境及气候条件下沥青纤维碎石封层技术设计的推广应用提供一定的实践参考。
[Abstract]:With the more and more extensive application of asphalt pavement, the problem of road disease has gradually aroused the attention of relevant departments. How to carry out the preventive maintenance of asphalt pavement reasonably and effectively has become a problem that must be considered in the design of asphalt pavement.Asphalt fiber macadam sealing technology can effectively improve the road disease of asphalt pavement.At present, the technology has gained more engineering experience in foreign countries, but it is seldom used in China.The related design experience is still lacking, and there is great blindness and arbitrariness in practical engineering application.Based on the engineering example of road surface maintenance of G320 in Zhejiang province, this paper investigates the pavement disease and its surrounding climate of G320 province, analyzes the main pavement diseases, and analyzes the causes of the disease.The methods of dealing with pavement diseases are put forward.Through the preventive maintenance and treatment of 1cm fiber asphalt gravel seal layer, the driving condition is improved and the pavement service life is prolonged.According to the follow-up investigation: after using the preventive maintenance technology of asphalt fiber gravel seal layer, the pavement has been used well and the driving environment has been greatly improved. This technology has blocked the damage to the pavement structure caused by Rain Water's seepage.The cycle of pavement cracks is slowed down, and the service life of pavement is prolonged.Moreover, the investigation found that: with the passage of time, the pan-oil and threshing of asphalt fiber gravel seal appeared, and gradually developed into desquamate. Besides the construction quality management, it is still necessary to select the technical material and determine the amount of the material.The construction technology optimization and so on carries on the deeper research.To sum up, through the project design and follow-up evaluation, the proposed amount of asphalt fiber macadam seal layer and the reasonable construction suggestion are put forward.In addition, the application research can provide some practical reference for the popularization and application of asphalt fiber macadam sealing technology design under similar geographical and climatic conditions.
