Experimental study on resilient modulus of liquid silicon dioxide (SI02) stabiuzed subgrade soil

Village and estate roads have failed to function due to damage at earlier stage of construction and this required frequent maintenance. Weak sub-grade is the basic factor of exponential damage. In order to overcome this problem, many procedures have been developed to improve the physical behav...

Experimental study on resilient modulus of liquid silicon dioxide (SI02) stabiuzed subgrade soil
description Village and estate roads have failed to function due to damage at earlier stage of construction and this required frequent maintenance. Weak sub-grade is the basic factor of exponential damage. In order to overcome this problem, many procedures have been developed to improve the physical behavior (strength or stiffness) of the sub grade soil. One of the procedures is to incorporate a wide range of stabilizing agent, additives or conditioners. Silicon dioxide (Si02) is a water based sodium silicate which is currently being patented on application by Probase Manufacturing Sdn.Bhd. to stabilize subgrade soils. The main objective of this research is to determine the resilient modulus of the liquid Si02 stabilized sub grade soil at number of state conditions (i.e. density, moisture content and amount of stabilizer).
