Tyre or road interface stresses are those induced by vehicular traffic running on roads, and are the primary cause of surfacing problems. The cost of asphalt layers is often the most significant in road construction and maintenance work. It is therefore of great importance to design towards an optimum asphalt layer type and thickness in relation to the supporting road structure, and the expected axle or tyre loading and tyre contact stresses.
