Abstract

Enhancements have been made to ground penetrating radar (GPR) technology to offer pavement engineers quantitative, non-destructive thiclrness measurements of multiple layers in pavement structures. The enhancements include a self-calibrating capability at every measurement location, signal penetration to a depth of 2 metres, resolution of layers as thin as 50 mm, and semi-automated processing and interpretation software. More than 125 thiclrness comparisons, made in Canada, the United States and Finland over a variety of pavement structures, gave GPR measurements of asphalt thiclrness accurate to within +5% of thiclmess measurements obtained by coring.
