Various forms of road deterioration from localized surface defects to serious distresses are commonly water related. Granular materials contain some fines, which are more or less sensitive to moisture, causing subsequent structural movement. CON-AID assists in changing the physical characteristic of clay particles to achieve better engineering characteristics. It is applicable to strengthening pavement fatigue, in rehabilitating resilient road pavements and upgrading local materials to acceptable standards.
 
 In contrast to other stabilizing techniques, CON-AID is refined to an accepted granular sequence, which is applicable to many local environments. No special mechanical equipment is required for the work execution. Although the design of the road is similar to the conventional way, CON-AID helps reduction in pavement thickness and improves in-situ (local) material to use as part of the pavement structure. CON-AID soil stabilizer assists workability and accelerates compaction with less effort.
 
 From the special tests conducted, there is no doubt that CON-AID works through reduction of surface tension and capillary rise, therefore there is a need to modify the conventional way of testing the soil to demonstrate the effectiveness of this stabilizer.
 
 Apart from standard physical property tests, such Atterberg limits, gradation curve etc., the governing test for design has to be CBR test. To measure the increase in CBR value due to CON-AID treatment, it is necessary to conduct the CBR test at the expected equilibrium water content, that is, the sample should be tested at approximately 50% of the optimum water content since the special tests have clearly indicated the magnitude of reduction in the water content.
 
 Although different soil compositions may give variation in reduction factor, pressure plate tests could be conducted to measure this value before applying the factor to the tested soils. In the guidelines prepared by the Transport Research Laboratory (TRL), there are some recommendations on designing pavement based on expected capillary level in the pavement structure; in other words, laboratory tests should be performed according to the actual field condition with respect to the reduction in water content after treatment. It is concluded that conventional way of determining the CBR values under soaked condition will not be an appropriate testing method for this type of soil stabilizer because the stabilizer is recommended to be applied to soil above groundwater table only.

 CON-AID is applicable in the following areas:

Economical Roads	Airstrips
Road Shoulders	Storage Areas
Parking Areas	Rehabilitation of Roads
