Laboratory investigation of the effect of temperature on frictional properties of concrete pavements containing crushed glass

In this research the effect of temperature on skid resistance of concrete pavements has been evaluated. An experimental approach has been used for this purpose and concrete mixtures containing crushed glass as fine aggregate with different surface textures were tested at different temperatures using British Pendulum Tester, so that concrete mixtures containing crushed glass with 3 different surface textures with different patterns of contact surface (smooth, brushed, grooved) were evaluated at temperature range from 0 °C to 50 °C. The optimum amount of crushed glass in concrete mixtures was determined using the compressive strength test and the mixtures produced by virgin lime aggregates were taken as control mixture. The results indicated that the skid resistance of concrete mixtures with brushed surface had the highest amount compared to other surface textures. Crushed glass aggregates had a positive effect on compressive strength, flexural strength and skid resistance of concrete pavements. It was also found that the skid resistance of all mixtures decreased with an increase in temperature.
