title: GPR Indicators of Identifying the Boundaries of Asphalt Concrete and Cement Concrete Layers
abstract: In order to realize the reinforcement of the existing road pavement it is essential to know its internal structure. One of the important tasks is the localization of concrete slabs under asphalt concrete pavement. The GPR method is used successfully in solving these problems [1,2]. The paper reviews the results of GPR surveying for determining old cement concrete slabs location under asphalt concrete pavement on section of the Highway М-2 “Crimea” in the Moscow Region of the Russian Federation.
