Lean Concrete Base (LCB), also known as econocrete or cement-treated base, is a low-cement content concrete used as a base layer beneath asphalt or concrete pavements. The use of LCB significantly impacts the long-term performance of overlying pavements. Increased structural capacity is a key benefit. LCB provides a stiff and stable base layer that increases the overall structural capacity of the pavement system. This reduces stresses and strains in the overlying pavement layers, extending their service life. Improved load distribution occurs because LCB distributes traffic loads over a wider area, reducing stress concentrations and minimizing rutting ....
