道路基础设施的可持续性,对保障人员通行和货物运输至关重要。随着道路网络的加密和商用车辆承载量的提升,则需要投入更多资金来维持道路网络的持续扩张。道路预防性维护措施,可降低早期损坏风险、减缓路面缺陷的发展速度,高效地延长路面实际使用寿命。PICPs预防性维护的关键:在正确的时间段、采取适宜的措施。制定预防性维护计划的目的,就是确定如何从预防性维修中获得最大的经济效益,及时判别和选择最有益的维护措施、并加以实施。对于有设计交通负荷量的路面,本文提出日常运营和维护指南,以保证透水性路面具有正常的雨水渗透和结构支撑功能。提出透水性路面高效维护所需要的预防措施、以及特定的性能指标判定值;保证路面长期渗透性及其评价方法和测试过程。预防性维护工作内容包括:路面的渗透性、结构稳定性——例如路面边缘围挡的局部缺陷、车辙印、路面砖开裂破损等,以及超出该范围的严重损坏,还包括对任何缺陷损伤的修复等。本文为每年对PICPs进行性能监测,提出了具体建议,并为路面有效维修提出详细的施工指南。
The sustainability of the road infrastructure is crucial to the protection of personnel and transport of goods. As road networks become more encrypted and commercial vehicles carry more capacity, more will need to be invested to sustain the continued expansion of the road network. Preventive maintenance measures can reduce the risk of early damage, slow down the development of road defects, and effectively extend the actual service life of pavements. The key to preventative maintenance of PICPs: Take the right measures at the right time. The purpose of developing a preventive maintenance program is to determine how to maximize the economic benefits of preventive maintenance and to identify and implement the most beneficial maintenance measures in a timely manner. For roads with designed traffic loads, this paper presents guidelines for day-to-day operations and maintenance to ensure that the pervious pavement has normal rainwater infiltration and structural support. Proposed preventive measures for efficient maintenance of water-permeable pavement, as well as the specific performance indicators to determine the value; to ensure long-term permeability of the road and its evaluation methods and testing process. Preventive maintenance activities include: Permeability of the pavement, structural stability - such as localized defects in the perimeter of the pavement, rut printing, cracked paving cracks, and serious damage beyond that range, as well as any damage Repair and so on. In this paper, annual performance monitoring of PICPs was made, specific suggestions were put forward, and detailed construction guidelines for effective maintenance of pavements were provided.
