The performance of demolition waste infiledl geocell in subgrade was studied using laboratory flexure testing and subgrade rutting analysis using KENPAVE software. The results obtained were compared with other infill materials: soil and sand. Flexural behaviour was determined using four-point bending tests, with results in terms of modulus improvement factor (MIF). Elastic modulus from the bending test was used for pavement design and software analysis. The geocells were prepared with three aspect ratios. Subgrade rutting life was obtained in terms of Equivalent Single Axle Load (ESAL) and Traffic Benefit Ratio (TBR) from software results. Demolition waste infilled geocell mattress with aspect ratio 0.67 showed improved behaviour in MIF and TBR followed by soil and sand. An attempt was made to create linear regression model for prediction of modulus of reinforced subgrade. Hence, subgrade reinforced with demolition waste as infill can improve pavement performance with economical and sustainable approach in pavement design.

采用实验室弯曲试验和使用KENPAVE软件的路基车辙分析，研究了路基中拆除废物infiledl土工格室的性能。将获得的结果与其他填充材料进行了比较：土壤和沙子。使用四点弯曲试验确定弯曲行为，结果以模量改进因子 (MIF) 表示。弯曲试验的弹性模量用于路面设计和软件分析。土工格室以三个纵横比制备。根据软件结果，根据等效单轴载荷 (ESAL) 和交通效益比 (TBR) 获得路基车辙寿命。纵横比为 0.67 的拆除废物填充土工格床垫在 MIF 和 TBR 中表现出改善的性能，其次是土壤和沙子。尝试建立线性回归模型来预测加筋路基的模量。因此，在路面设计中采用经济和可持续的方法，以拆除废物作为填充物加固路基可以提高路面性能。
