The volumetric analysis of asphalt mixtures mainly makes use of standard laboratory design tests. The Belgian Road Research Centre has developed an analytical computer programme (PRADO) that assists in desktop volumetric design. The University of Stellenbosch in co-operation with MUCH Asphalt has undertaken desktop volumetric analysis using PRADO on two asphalt mixes, a wearing course mix and an asphalt base mix. The analysis focussed on the determination of an optimal grading and optimal composition of the several aggregate fractions available. It was also used to predict volumetric properties such as voids in mineral aggregate (VMA), voids in mix (VIM) and voids filled with bitumen (VFB). This paper presents the results of these analyses and compares the predicted values with the actual volumetric properties as determined in standard laboratory design tests.167500 bytesapplication/pdfenUniversity of PretoriaTransportVolumetric analysisPradoTransportation -- South Africa -- CongressesAsphalt -- South Africa -- CongressesRoad materials -- South Africa -- CongressesRoad materials -- South Africa-- TestingAsphalt emulsion mixtures -- Specifications -- South AfricaEvent
