摘要 路面预防性养护可以达到延长路面使用寿命、提高道路服务质量、延长中修或大修期限的目的,而预防性养护指标的确定及相应措施决策是实施预防性养护的前提。本文依据山东省高速公路检测数据以及国内外对于预防性养护指标研究状况,对预防性养护指标的选取原则进行了论述。分析认为,选取路面PCI、RQI、RI及抗滑性能指标作为预防性养护指标是合理的,并且对上述指标范围进行了研究。最终依据整体分析数据、已有工程验证及现有研究资料,最终提出适用于山东地区的预防性养护指标体系。在PSSI 】80的前提下,该指标体系以路面状况损坏指数PCI值作为第一类标准,以RQI、RDI及SFC为第二类指标,第二类指标是在满足第一类标准下的判断性标准。 Preventive maintenance of pavement can prolong the service life of pavement, improve the quality of road service and prolong the period of intermediate or major repairs. The determina-tion of preventive maintenance index and the decision-making of corresponding measures are the advance of implementing preventive maintenance. Based on the Shandong Province highway detection data and the research status of preventive maintenance indicators at home and abroad, this paper discusses the selection principles of preventive maintenance indicators. It is reasona-ble to select PCI, RQI, RI and anti-skid performance indicators as preventive maintenance indi-cators, and their respective ranges are studied. Finally, according to the overall analysis data, the existing project validation and the existing research data, the preventive maintenance index system suitable for Shandong area is put forward. Under the premise of PSSI >80, the index system regards PCI value of pavement condition damage index as the first standard, RQI, RDI and SFC as the second index, and the second index is the judgment standard under meeting the first standard.
