Abstract (en)
[origin: EP2154293A2] The presented road surface construction is designed for motorways in order to avoid cracking and crumbling of the asphalt surface. The road surface construction includes a rigid base (1), an elastic base (2), a compensator (3) for vertical and horizontal deformations of the rigid base (1), a drain layer (4), a bed for the surface (5), a net for receiving and diffusing shear stress (6), elastic deformable adhesive layers (7), a mounting layer for the surface (8), a net (9) for receiving and diffusing shear stress from the surface (10), a two-layer surface (10), and drains (11).
