旧路材料性能试验评价在旧路改造及养护设计工程中的应用

Application of Evaluation on Performance Test of Old Road Materials in Old Road Reconstruction and Maintenance Design Engineering

旧路状况的科学分析与科学决策是旧路改造及养护项目建设的关键,旧路结构和材料的评价与应用是科学决策与方案设计的技术重点,旧路材料性能评价试验应结合功能需求和设计目标进行有针对性的选择,避免固定选项式试验标准。以庄林线路面工程为例,阐述了在旧路改造及养护项目设计中,旧路材料性能评价对旧路状况科学化诊断和设计方案科学决策的重要作用。

The scientific analysis and decision-making of the old road condition is the key to the reconstruction and maintenance project construction of the old road.The evaluation and application of the old road structure and materials are the technical key points of the scientific decision-making and scheme design.The performance evaluation test of the old road materials should be carried out in combination with the functional requirements and design objectives,so as to avoid the fixed option test standard.Taking Zhuanglin road surface engineering as an example,the important role of the performance evaluation of the old road materials on the scientific diagnosis of the old road condition and the scientific decision-making of the design scheme in the design of the old road reconstruction and maintenance project are elaborated.
