A test road section of experimental pavement structures in Lithuania (I)

Abstract

The rapid growth of heavy traffic, the increase in the standard axle load from 10 to 11,5 tonnes on the main roads of Lithuania make the scientists to look for new durable road building materials and their mixes. The continuously increasing need for the strengthening of road pavement structures induces to use new road reconstruction technologies, to search for new methods in constructing pavement structural layers, to investigate pavement structures under real conditions. The article gives the program of experimental investigations of a test road section constructed for the first time in the road history of Lithuania and consisting of 24 different pavement structures. The article also describes the initial results of investigations. Further investigation results, their analysis and evaluation will give a possibility to choose road pavement structures the most suitable to Lithuanian climatic and traffic conditions.
