Performance of asphalt pavement structures in test road sections
Santrauka
The experimental pavement test road section program was carried out in 2007–2013 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. Final results after five years of monitoring indicate the performance of typical Lithuania flexible pavement structures influenced by different traffic loads. The total number of ESAL’s (100 kN) at the end of December 2013 was 480 000.
