Abstract
It is an obvious fact that most highway in the country are uncomfortable and intolerable to motorist, this makes travelling on roads a misery to those who could not afford the other transportation options. This situation is as bad that if urgent action is not taken, it could take away the confident and comfort of travelling on roads, which includes the security of being at the wheel by oneself. The big question which puzzles the mind of many is, what could have been the cause of incessant occurrence of failures on our roads, just after construction in Nigeria, thus creating doubts regarding the strength provided for the pavements, since usually a stable pavement should last for the design period (of about 20years) taking the anticipated traffic loads and at minimal maintenance cost. The ground on which pavement are placed consist of soil mass to a reasonable depth within the earth crust and must be made stable at the beginning of a road construction, hence the need for stabilization where the ground is less stable to improve the strength and consequently the pavement structure. When the soil is adequately provided with consideration for climatic variation along the length on the route, there should be little fear of road failure for the intended useage and provided maintenance works are implemented routinely to make up for the service situation and prevailing environmental conditions.
