ABSTRACT:
There is provided a proof body for use in a strain gauge for measuring horizontal strains in a pavement. The proof body is to be inserted in a hole provided in a surface layer of the pavement. The proof body is designed to be embedded in a substitute core designed to be retrofitted in the hole. The proof body is designed to be attached to the walls of the hole, allowing measurement of horizontal strains in the pavement surface layer.
