THERMAL CONDITIONS OF ROAD PAVEMENTS AND THEIR INFLUENCE ON MOTOR TRAFFIC

An analysis is presented of how climactic conditions in the Republic of Lithuania affect road pavements and how their performance affects motor traffic. The main properties of asphalt concrete mixtures as they are affected by temperature are described through experimental data. The findings show that they tend to show more plasticity when the pavement is between 20-40 degrees centigrade. Since Lithuania is located in the northern part of the middle climate zone, the solar energy from the sun us moderate. Atmospheric patterns contribute to an uneven distribution of temperatures on the surface, but the range is not great. The nearness to the sea means the winder is warmer, spring is cooler and fall is longer and warmer. This generally warmer climate suggests that movement of heavier vehicles be restricted on hot summer days during the sunlight hours to avoid serious pavement damage. And in general, lower axle load limits should be imposed in warmer months.
