ABSTRACT

This paper describes an analysis of concrete pavement loading while taking into account deflections and deformations. Concrete pavements are generally durable and have low demands on maintenance within their whole lifecycle. The first part describes an experimental road test section with verified material characteristics of individual pavement construction layers by laboratory and non-destructive testing. Furthermore, the position of temperature sensors in road structure is described, together with loading data and data from a strain sensor placed on the bottom part of a concrete slab. Pilot testing provides valuable information about the stress condition of concrete pavement in detail, importance of monitoring the non-linear temperature gradient and curvature of concrete pavement slab during the measurement. According to performed experiment are derived conclusions important for the use in practice. After verifying the work of the sensor on the test section and in real traffic, it can be used in the system of pavement response monitoring on highways.

Keywords: concrete pavement, strain gauge, response, deformation
