摘要
该文介绍了塑料类土工格栅具有抗拉强度高(大约是150-200tmpu)、摩擦系数大(0.8左右)、抗蠕变性好(超过120)、变形率小、耐久性强、施工方便等优点。对此,在道路工程中可用于新建沥青路面结构层、老路补强、加固软基、减少新老路基差异沉降、加筋路堤和挡墙等方面的施工,对抗疲劳开裂、耐高温车辙、减少反射裂缝等方面的能力有明显的帮助。
The article introduces the advantages of the plastic earth grid, i.e. high tensile strength (about 150~200 tmpu), large friction coefficient (about 0.8), good creep resistance (exceeding 120), small deforming rate, strong durability, convenient construction and etc. Therefore, it can be used in newly building the asphalt pavement structure layer, strengthening old road, reinforcing the soft subgrade, decreasing the different settlements of the new and old roadbeds, constructing the stiffened embankment and retaining wall of the road engineering, and has the obvious help in the capability of the fatigue resistant cracking, high-temperature tracking and reducing reflection crack.
