🛣️ ASTM D4748 (Air-Coupled Horn Antenna 1.0-2.0 GHz, Layer Thickness mm @ 60 MPH)

GPR Pavement Layer Thickness Calculator

Model high-speed non-destructive pavement thickness evaluation using air-coupled horn GPR antennas mounted on highway survey vehicles under ASTM D4748: calculate asphalt surface layer, binder course, and crushed aggregate base thickness (mm) at full highway traffic speed (60 MPH without lane closures), and highway asset management profits.
