  • Patent number: 5630674
    Abstract: A road surface formed by laying a multiplicity of molded elastic plates 2 each containing a rubber material 6 mixed with an aggregate 7 having anti-wear properties. These elastic plates 2 are laid on a roadbed 3, and are fixed by fixing means 20. Strong adhesive force between this rubber material and the aggregate greatly suppresses peeling of the aggregate 7 from the rubber 6 and prevent formation of pit holes on the surface of the road. The highly elastic nature of the elastic plates prevents plastic deformation and cracks of the road due to vehicle load, suffer little change with temperature variation, providing long-term durability. Accordingly, the frequency of repairs or modifications carried out to improve durability is drastically reduced, and the number of defects is reduced so that the safety of vehicles using the road is increased.
