Dry Lean Concrete (DLC), Procedure of DLC, Advantage
WEBJul 27, 2023 · Rigid pavement typically uses DLC as a base or sub-base. It prevents mud pumping and provides stability for heavy machinery and solid pavement. The procedure of DLC: The prepared sub-grade is sprinkled with water to moisten the surface prior to the building of a dry lean concrete sub-base.
WEBDry lean concrete is most common sub-base/base course in the rigid pavement components [3]. DLC is no slump concrete with high ratio of aggregate to cement in comparison with conventional cement concrete. The minimum required cement quantity for manufacturing of DLC is 140 kg/m3 [2].
