Evaluation of change of structural and exploatation conditions of the raod of experimental pavement structures

Abstract

This paper presents the first experimantal pavement test road section in Lithuania including pavement design, annual measurements, data acquisition and response analysis. The road of experimental pavement structures was constructed in 2007. Its laid on the road to the query, one traffic lane is used by loaded traffic and other – by unloaded traffic. The road consists of 27 different pavement structures with the same class of pavement structure but the different type and composition of materials. 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) in February 2013 was 353 000.
