Beyond its roles in load distribution and providing a construction platform, the sub-base layer in road construction can serve as a crucial drainage element. In thicker pavements, water leakage from the surface is minimal, and the sub-base primarily functions to support traffic loads. However, in thinner pavements, water penetration can be significant. In such cases, the sub-base takes on the additional responsibility of a drainage layer, channeling water away from the pavement structure. This dual functionality enhances the pavement’s longevity and performance by mitigating the detrimental effects of water infiltration.
