高速公路改扩建工程路基路面拼宽技术研究

Research on the widening technology of subgrade and pavement in highway reconstruction and extension projects

青岛至济南高速公路(邹平至济南段)改扩建工程总体方案是以两侧对称拼宽为主,局部采用单侧拼宽。介绍了减小路基差异沉降、路面裂缝的措施。

The general scheme of the reconstruction and extension project of Qingdao to Jinan highway （Zhouping to Jinan section） is giving priority to bilateral symmetry widening, locally based on unilateral widening. This paper introduces measures for decreasing the differential settlement of subgrade and pavement cracks.
