Author:Komba, Julius J; Mataka, M; Malisa, JT; Walubita, LF; Maina, JWDate:Jun 2018Traffic loading is one of key inputs for new and rehabilitation designs of pavement. Heavy vehicles cause the most structural damage to pavements; hence, as part of the pavement design process, heavy vehicle volume, and axle load surveys are ...Read more
Author:Gass, BG; Ventura, DFC; De Beer, MorrisDate:Mar 1993The use of stabilised layers is cost effective in road construction in South Africa. Some stabilised materials have however been found to be susceptible to erosion. To identify erodible materials the Erosion Test was developed in 1989. ...Read more
Author:Denneman, EDate:May 2011An innovative pavement system known as Ultra Thin Continuously Reinforced Concrete Pavement (UTCRCP) was recently developed in South Africa. The technology is currently being implemented on some major routes in the country. The system consists ...Read more
Author:Mgangira, Martin B; Paige-Green, PDate:Nov 2008This paper discusses a typical example of the distress experienced by a flexible pavement constructed over black clay soil, also commonly known as black cotton soil, where minimal precautionary measures were implemented. Black cotton soils ...Read more
Author:De Beer, Morris; Fisher, ColinDate:Sep 2016An important element of Accelerated Pavement Testing (APT) is the selection of appropriate test tyre(s) to be used for APT testing. By far the majority of full scale (or scaled) APT devices uses pneumatic rubber tyres. Tyres differ not only ...Read more
Author:Komba, Julius J; Mataka, M; Malisa, JT; Walubita, LF; Maina, JWDate:Jul 2018Traffic loading is one of the key inputs for the structural design of pavements. For pavement design purposes, heavy vehicles are mostly used for the estimation of the traffic load spectra, as they cause the most structural damage to pavements. ...Read more
