Abstract

At present, in the Republic of Lithuania there are 21,300 km of state roads. Low-volume roads do not comply with the rapidly increasing traffic in terms of their technical and operational parameters. Since 1998, gravel road (low-volume road) paving programmes have been implemented in Lithuania. It is planned that the length of low-volume roads in the total state road network will decrease to 32 % from 54% by 2015. When selecting low-volume road routes for asphalt paving, solving pavement structure design issues according to the research data of gravel road structures to be asphalt paved as well as the study of local conditions, the enhancement of investment in gravel road paving is expressed through the substantiated reduction of gravel road paving costs and the increase of internal rate of return.
