Evaluation of Surface Deformation in Geocell-Reinforced and Unreinforced Bases Over Weak Subgrade
Geocell, a type of geosynthetic material widely used as reinforcement, has encouraged the civil engineers to build roads over weak subgrades. Major concerns in pavement construction are lack of good constructions sites and inadequate base course structural strength. Pavement undergoes two types of failures, viz., rutting and distress. Geocell plays a vital role in reduction of surface deformations by providing a three-dimensional cellular confinement. Static plate load tests were conducted on unreinforced and geocell-reinforced bases to study the effect on surface deformations. Geocell with three different heights (100, 125 and 150 mm) were used to reinforce base course. This paper contributes to understanding how geocell reinforcement lowers the surface deformations in pavements. Thickness of base plays a crucial role in stability of pavement, the effect of varying base course thickness was also investigated, and it was observed that with increase in base thickness the load distributed over a wider area thus decreasing the effects of rutting. The paper also discusses the increase in bearing capacity ratio due to geocell reinforcement. The overall findings showed that with the inclusion of geocell in base course, and the surface deformations decreased.
