Abstract


The rapid growth of heavy traffic, the increase in the standard axle load make scientists to look forward for new durable road constructing materials and their mixes. The continuously increasing need for strengthening the road pavement structures induces to use new road reconstruction technologies, to search for new methods in constructing pavement structural layers and investigate pavement structures under real conditions. The article presents construction of experimental pavement structures for the first time in the road history of Lithuania. The article also describes the installation process of stress and strain transducers in different layers of experimental pavement structures and initial results of stress and strain measurements. These measurements will be carried out each time after passed 20 000 ESAL’s calculated to 100 kN.


Keywords:

road pavement structure; test road section; stress; strain; transducer; ruts; skid resistance; roughness of pavement
