Dynamics of Vehicle Loads on the Asphalt Pavement of European Roads Which Cross Lithuania

Abstract

The largest damage to the road pavements is caused by the heavy goods vehicles (HGV's). Due to large axle loads, which often assume a dynamic effect, the HGV's account for almost the total destructive impact on the road pavement, though they make about 15 % of the total traffic flows on the main roads of Lithuania. A continuous increase in the transit HGV's on the Lithuanian roads causes the permanent deformations of road pavements. Due to the insufficient pavement strength the ruts, waves, displacements and potholes are initiated. Based on the analysis of traffic volume it could be stated that the amount of vehicles on our roads has been annually growing. The largest loads are caused by HGV's, the average annual increase of which is 17 %. Based on the traffic volume measurement data of the Transport and Road Research Institute (TRRI) the annual average daily traffic (AADT) and the impact of the HGV's on the road pavements was identified on separate sections of the roads E85 and E67. The impact was determined by calculating the equivalent standard axle (ESA).
