Abstract
In an effort to reduce fuel consumption and CO2, a measurement program initiated by Rijkswaterstaat and province Gelderland was conducted in 2013 to investigate the variation in rolling resistance of passenger cars tyres on different asphalt road surface types on the Dutch main roads (highways and provincial roads). Complementary to the rolling resistance measurements also texture measurements were performed. In addition to this program rolling resistance and texture measurements have been performed on some concrete road sections for the Cement&BetonCentrum. In total 8 concrete road sections were selected and measured. The measurements were a joint effort by M+P and TU-Gdansk. All the concrete road sections were measured on April 2013. The rolling resistance and texture were measured simultaneously. A temperature correction based on the tyre wall side temperature was applied to all rolling resistance coefficients. Two types of concrete road surfaces were measured: brushed concrete (1 road section) and exposed aggregate concrete (7 road sections of different ages: from 8 to 22 years old pavements!). The difference in average rolling resistance coefficient between brushed concrete and exposed aggregate concrete is 0.9 ± 0.4 kg/t (or 10 ± 4 %). This is a significant difference.
