Cement Treated Sub Base ( CTSB)
As per MORT&H clause 403
Introduction : -
In India the pavement construction is improved and give much strength with the use of Cement /lime treatment has become an accepted method for increasing the strength and durability of sub base like GSB and marginal aggregates, reducing quantity of aggregates. Indian roads congress (IRC) developed a special publication for mix design of base/ subgrade. No pavement design guideline is presently available cement treated sub base. To overcome this problem, the objective of present research work is to develop a pavement design chart using cement and lime stabilized sub base for rural and urban roads with light and medium traffic (up to 50 MSA). It not only saves money but also helps to increase life cycle of roads.
