This paper was presented at Session 23 - Pavement Performance. It describes a laboratory trafficking test on dolerite road base material. The aggregate was installed in the test machine at a range of moisture contents and densities and loaded by a rolling wheel. The relative performance of the bases is assessed from measurements of the permanent deformation. Results from the test show that the deformation behaviour is very dependent on the moisture content, whilst differences in density have much less effect. If the base can be kept at a low moisture content, about 3 per cent, the deformations should be small, but the material will readily take up water. (TRRL)
