EXECUTING METHOD OF THICKNESS-MEASURABLE PAVEMENT FACILITY AND MEASURING METHOD OF THICKNESS OF PAVEMENT OF PAVEMENT FACILITY

摘要

PURPOSE:To measure the thickness of a layer formed in the sectional direction without breaking a pavement facility when the pavement facility is constructed on a road, etc. CONSTITUTION:Substances having different dielectric constants such as iron powder, aluminum powder or the like and asphalt concrete or cement concrete are scattered on the underside boundary surface of a layer, pavement thickness of which must be measured, in each layer formed in the sectional direction of a pavement facility in the construction process of the pavement facility. A layer just above the layer is constructed, electromagnetic waves are radiated, and layer thickness is measured by the reflection of electromagnetic waves.
