Conformable magnetic articles underlaid beneath traffic-bearing surfaces
First Claim
1. A conformable magnetic article for underlayment beneath a traffic-bearing surface to send a magnetic signal to a sensor traveling over the traffic-bearing surface, said magnetic article comprising at least one conformable magnetic layer comprising a binder and a sufficient amount of magnetic particles within the binder to provide the magnetic signal, the conformable layer being sufficiently conformable to meet the inelastic deformation test, wherein said article is perforated along its length.

Abstract
A conformable magnetic article for underlayment beneath a traffic-bearing surface which sends a magnetic signal to a sensor traveling over the traffic-bearing structure. The magnetic article comprises at least one conformable magnetic layer 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.
