CONFORMABLE MAGNETIC ARTICLES UNDERLAID BENEATH TRAFFIC-BEARING SURFACES

摘要

A conformable magnetic article (300) for underlayment beneath a traffic- bearing surface which sends a magnetic signal to a sensor travelling over the traffic-bearing structure. The magnetic article comprise s at least one conformable magnetic layer (2) comprising a binder and a sufficient amount of magnetic particles dispersed within the binder to provide a magnetic signal through the traffic-bearing structure to a sensor.
