A road mat with a replaceable sacrificial outer layer. The road mat generally consists of an exterior framework housing an interior load - bearing core. The road mat core is designed to be a load bearing structure and to allow the mat to sit more or less level on the surface it is placed. The road mat core usually consisting of wood or some derivation or amalgamation of a wood product that is fashioned to fit within the road mat framework. Newer designs are employing various composite material cores in an effort to reduce weight and extend core longevity. The fact is that the types of machines that are traversing the road mat are very heavy and generally destructive to the road mat core. Therefore a road mat with a replaceable sacrificial layer on top of, or surrounding the core, will be beneficial in that the outer layer or skin will take the brunt of the forces being imposed on the road mat by the equipment. Any subsequent damage to the outer layer or skin can be easily rectified by simply replacing the sacrificial outer layer while leaving the road mat core intact. Conversely, by employing a two piece core it is possible to design the characteristics of core to be different than the outer laver(s). There may be advantage to this design in that separate materials can be specified for the load - bearing core and for the outer layer. The material specification for a load bearing assembly may be quite different than the material specification for the core outer layer(s) which are constantly in contact with the destructive forces of the work arena as well as the environment. By utilizing a two piece core design it is possible to specify the materials for each distinct component making it possible to better optimize the core performance.
