THE BENEFICIAL EFFECT OF CEMENT-TREATED SUBBASES IN PAVEMENTS WITH UNTREATED CRUSHER-RUN BASES

Untreated crusher-run is frequently used as basecourse material in South Africa and such pavements have performed satisfactorily. Some of these pavements have cement-treated subbases. This report describes the beneficial effect of a cement-treated subbase underneath the untreated base. The results of the AASHO road test, layered elastic theory and the performance of such pavements in South African full-scale road experiments are used to prove that a large part of the successful performance of the pavements containing untreated bases must be attributed to the cement-treated subbases.
