Lateral restraint
Lateral restraint
Horizontal reinforcement , often referred as lateral restraint, reduces the horizontal deformation of base course and subgrade material where they are in contact with the geotextile. The geotextile holds the base material and subgrade together by developing frictional forces between itself and the material.
The positive result of lateral restraint is that there is better load distribution in the base course material , for a particular vehicle load, the subgrade is less heavily loaded . In addition the subgrade tends to be less deformed because some of the
