为了调查江苏省各种路面养护措施的费用效益,对路面管理系统的养护历史资料、交通轴载信息、路面性能的数据进行观察和分析。与增长模型、线性模型、对数模型和指数模型相比,立方模型具有更高的回归精度,能够捕捉路面性能衰退曲线,因此采用立方模型来模拟路面车辙的发展。计算效益费用比来定量评价路面养护措施的费用效益。研究结果表明,在中、低交通条件下,热拌沥青薄层罩面和微表处比其他养护措施的费用效益更大;在重、特重交通高速公路上,热再生和厚热沥青罩面具有更长的使用寿命和更大的费用效益。
為瞭調查江囌省各種路麵養護措施的費用效益,對路麵管理繫統的養護歷史資料、交通軸載信息、路麵性能的數據進行觀察和分析。與增長模型、線性模型、對數模型和指數模型相比,立方模型具有更高的迴歸精度,能夠捕捉路麵性能衰退麯線,因此採用立方模型來模擬路麵車轍的髮展。計算效益費用比來定量評價路麵養護措施的費用效益。研究結果錶明,在中、低交通條件下,熱拌瀝青薄層罩麵和微錶處比其他養護措施的費用效益更大;在重、特重交通高速公路上,熱再生和厚熱瀝青罩麵具有更長的使用壽命和更大的費用效益。

To investigate the cost-effectiveness of different maintenance treatments of highways in Jiangsu Province the historical pavement maintenance records traffic load information and pavement performance data in the pavement management system PMS are recorded and analyzed. Compared with the growth model the linear model the logarithm model and the exponential model the cubic model has higher regression accuracy R2 and it can capture the sigmoid shape of the deterioration curve.So it is selected to simulate the pavement rutting development.The benefit over cost ratio is calculated to quantify the treatment cost-effectiveness.The analysis results show that thin hot mix asphalt HMA overlays and micro surfacing are more cost-effective than the other two treatments on light and moderate traffic roads.Hot in-place recycling and thick HMA overlays have much longer service lives and greater cost-effectiveness under heavy or extra heavy traffic.
