The benefit of reinforcement in pavement sections can be quantified in terms of Layer Coefficient Ratio (LCR). In the present study, a series of Large-Scale Model Experiments (LSMEs) were conducted to quantify the LCRs considering unreinforced and geogrid-reinforced base layers overlying soft to stiff subgrades. Based on extensive LSME testing of reinforced base layers, LCRs were found to range from 1.01 to 1.33. The existing design philosophy for flexible pavements is extended to design geogrid-reinforced flexible pavements based on LCR values.

柔性路面土工格栅加固基层层系数比的评估

可以根据层系数比 (LCR) 量化路面部分加固的好处。在本研究中，考虑到覆盖软到硬路基的未加筋和土工格栅加筋基层，进行了一系列大型模型实验 (LSME) 以量化 LCR。根据对增强基层的广泛 LSME 测试，发现 LCR 的范围从 1.01 到 1.33。现有的柔性路面设计理念扩展到基于 LCR 值设计土工格栅增强柔性路面。
