Saw Cutting

An inductive loop is a coil of electrically conducting wire embedded in the road’s surface. The road surface is marked up according to the loop array specification, and the asphalt is cut into using a diamond saw. The wire is then installed into the groove and connected to the roadside control box to test the system.

When the system testing has been completed, the installation is sealed with epoxy resin and recoated with oxidized bitumen to ensure that moisture cannot seep into the surface and reach the wire, which may result in corrupt measurement data being sent to the traffic management system.
