Performance of asphalt pavement structures in test road sections

Abstract

The experimental pavement test road section program was carried out in 2007-2014 by the Road Research Institute of Vilnius Gediminas technical university. The road of experimental pavement structures was constructed in 2007 and still continues its operation. The road consists of 27 different pavement structures with the same class of pavement structure, but the different type and composition of materials. The experimental pavement structures were laid on the road to the query, one traffic lane is used by loaded traffic and other – by unloaded traffic. This paper presents the first experimental pavement test road section in Lithuania including pavement design, annual measurements, data acquisition and response analysis. This road is affected by real climatic conditions and high intensity heavy vehicle traffic. The aim of such a research is to continuously monitor performance of different pavement structures and to elaborate on the most suitable and economically effective pavement structures. Final results after seven years of monitoring indicate the performance of typical Lithuania flexible pavement structures influenced by different traffic loads.
