AN EVALUATION OF LOW STANDARD PAVEMENTS IN THE SOUTH-WEST TRANSVAAL
As a trial in the late 1960's, the design standards for certain lightly-trafficked roads in the south-western Transvaal were lowered in order to reduce the costs and hence increase the length of roads which could be surfaced. One- and two-layer pavement designs were adopted. Based on the experience with these roads and a thorough structural evaluation of the performance after nine to twelve years' use, the low-standard specification is shown to be a viable and economic alternative to the normal provincial standard for a rural road. On the present worth of total costs it is shown to be 26 per cent cheaper than a similar pavement built to the normal standard. Recommendations are made for the design of pavements for low standard roads in farming areas having a relatively low rainfall. (Author/TRRL)
