高速公路改扩建工程路面结构方案研究

Schematic Research on the Pavement Structure of Expressway Reconstruction and Expansion Project

以黄石高速公路(辛集至藁城段)改扩建项目为依托,对高速公路改扩建拼宽路面及既有路面养护方案进行研究,制定了高速公路改扩建路面工程技术方案。兼顾老路养护需求与拼宽路面结构方案的协调,根据项目内侧加宽的特征,结合项目路段养护历史,确定了合理的整体路面建设方案。

Based on the reconstruction and expansion project of Huangshi expressway(Xinji-Gaocheng section),the maintenance schemes for the widening pavement and the existing pavement of expressway reconstruction and expansion are studied,and the technical scheme for the pavement engineering of expressway reconstruction and expansion is formulated.Taking the coordination between the maintenance needs of the old road and the structural scheme of the widening pavement into account,the reasonable overall pavement construction scheme is determined based on the characteristics of the internal widening of the project and the maintenance history of the project section.
