ABSTRACT
The performance of many flexible pavements also called Asphaltic Bituminous roads are not satisfactory, bearing in mind that the major highways in Nigeria were designed for a life span of between 10-15years. Based on estimated traffic volumes not exceeding 10tones exile loads, and the minor truck roads designed for a life span of 5-10 years. It has been observed that majority of the Nigerian roads failed before their designed life is attained, as a result of mis-use by over loading of vehicles. This paper examines historical background on rigid pavements, types of pavement, differences between rigid pavements and flexible pavements, Nigerian present Asphaltic pavement roads, recommendation and conclusion.
Keywords: Rigid pavements, flexible pavements
