... The maximum speed without sliding for wet asphalt is 26 km h-1, this is almost half the speed of dry asphalt. Uncertainty margins included, the velocities are; 25.9 and 26.8 km h-1. This is an expected case because if the road is wet, the rubber on the tyres are more slippery when initiating contact ...
