ABSTRACT  Travel along unpaved roads isn't perpetually assured, as a result of their low standards, poor riding quality, impassability in wet weather, and also the danger within the amount of dirt that's generated by moving vehicles and wind. Stabilization with electrochemical based nontraditional soil stabilization additives (chemical additives) might supply an answer to the current continual downside. The objective of this paper is to report on the strength behavior of a typical marginal quality worn quartz gravel material treated with 2 chemical based nontraditional soil stabilization additives, accelerator and sulphonated oil to assess their potential worth for cliché-topped building underneath wet and dry conditions. These treated panels were trafficked underneath a hundred vehicles per day. The analysis was done by means that of laboratory tests and field investigations for 3 years. The characteristics of the natural material and also the binding ability of the nontraditional soil stabilization additives were established from the laboratory testing. Density and wet, and also the strength development of the treated material were determined from field investigations. These 2 nontraditional soil stabilization additives seem to own affected the particles and their water element, thence a rise in densities was achieved. The degree of formation and paste encompassing the particles perceived to have varied with time and differed between the additives. a rise in density within the sulphonated oil additive treated panel occurred 3 months once construction, and an additional increase was once more detected eight months once construction (five months thereafter). Up to eight months once construction, the accelerator additive treated panel showed a major decrease in density, however showed a small increase thirtyone months once construction. This increase in densities would possibly in all probability be as a result of any compression by traffic. The variations in density were attributed to testing variability. In the in place and soaked DCPCBR strength measurements, the sulphonated oil additive treated panel reached its most in place strength at 2 months once construction, whereas the accelerator additive treated panel reached its most in place strength at 5 months once construction. Up to eight months once construction, each treated panels indicated a major decrease in each the in place and soaked DCPCBR strength conditions. The decrease was attributed to rain. There was, however, very little proof to indicate that the additives had improved the fabric, with the panel being systematically stronger in each them in place and soaked DCPCBR conditions. The importance of considering the time consider the strength development of nontraditional stabilization check techniques, additionally because the variety of tests, was highlighted within the results of this study. The natural variability of the materials utilized in this sort of study is usually high, and also the exactness of the check methodology is usually quite low. On this basis, it's sometimes tough to draw definite conclusions.
