CAN HIGH STRENGTH CONCRETE PAVEMENTS IMPROVE SIGHT CONDITIONS IN ROAD TUNNELS

Wear and tear on road pavements costs enormous sums of money in maintenance each year. Road dust is unpleasant and if found in larger quantities can cause health problems. Road tunnels are particularly prone to discomforts caused by the presence of dust. Reduction in visibility is one of the problems. Dust is chiefly caused by the continuous mechanical breaking down of the road pavements, combined with soot from vehicles. In winter the wear and tear from studded tires will give markedly worse visibility than in the summer. The amount of dust generated and the distribution of particles will bear direct relation to the quality of the road surface. In road tunnels the road pavement lightness strongly influences the operational costs of the tunnel lighting.
