IMPACT OF VEHICLE LOAD ON ASPHALTIC PAVEMEENT THICKNESS

Abstract

Road networking is one of the strategic priorities for economic, social and political development of every country. In Nigeria, road are constructed without much regard to standards and technique and because of bad quality of some roads materials and in some cases due to increasing traffic density on demand use. The settlement characteristics of threes road were examined based on the traffic composition of vehicles on each of the roads, the roads are Minna-Suleja Road, Minna-Kotangora Road and Minna - Bida Road. It was discovered these roads have settlement of 16mm, 20mm and 13mm respectively, which are above the acceptable values recommended by various standard. This clearly shows that the studied roads are overloaded and hence the frequent failure experienced on the roads. Equation was also promulgated for pavement settlement after care observation Y= 2x2e-14 - xe-7 + 100.4
