THE PERFORMANCE OF A HEAVILY- TRAFFICKED CONCRETE BLOCK PAVEMENT AT THE SHIRE OF FLINDERS

This report describes the design, construction, trafficking and performance of a concrete block test pavement at the Shire of Flinders, Victoria. The block pavement was over-designed compared to the Australian specification. The report describes the method used to determine the amount of traffic that used the pavement and the variation in rut depth, recoverable surface deflection, moisture content and subgrade CBR over time and trafficking. The pavement operated as an access road to a quarry. Its performance over two years service and about 150,000 ESAS was satisfactory. The skid resistance of the block pavement showed the same seasonal trends as two asphalt control sections, though the values obtained on the block pavement were nearly almost higher than those obtained on the asphalt pavements. The grading of the bedding sand used in the tests satisfied the Australian specification. (Author/TRRL)
