Advantage is taken from the retraction phenomenon in order to achieve an alternative indentation along the joints of adjacent slabs of continuous cast concrete, susceptible of forming satisfactorily a knee—or gimbal-joint connection between the joints. The process is complemented with a concrete separator element which facilitates the formation of the crack and prevents water from reaching the platform, and which can be fixed to said device. The invention applies to concrete surface roads, highways and harbour zones of goods warehouses and enables to design and make road surfaces without bases and subbases.

  • Patent number: 6708362
    Abstract: Prior art supported, load bearing concrete panels having flexural reinforcing materials within the top and bottom halves, are over-designed, and experience increased deterioration and increased severity of cracks in the top surface due to flexural reinforcing materials which are located within the top half of the panel. It is now taught that, by removing flexural reinforcing materials which are intended to carry carrying bending moment tension stresses in the top half of panels (12), over supports (14), while maintaining such flexural reinforcing materials (20) confined to the lower half of the panel, does not reduce the flexural strength of the panel (12) below that which is required to support expected loads. Such panels (12), without flexural reinforcing materials in the top half, exhibit improved durability and reduced top surface (16) cracking, and can be produced with fewer production steps and with reductions in the cost of materials.

  • Publication number: 20010002497
    Abstract: A geocomposite system for increasing the service life of roads, bridges, or the like, includes a geocomposite layer having a geomembrane disposed between two geotextile backings, a structural layer for supporting the geocomposite layer, and a base layer formed on top of the geocomposite layer. The geomembrane is impermeable and the geotextile backings are sufficiently porous to provide a wicking action of moisture or liquid laterally along the geomembrane and out of the geocomposite system to prevent moisture or liquid damage. The geomembrane prevents the intrusion of liquids including deicing salts into the structural layers of roads, bridges, or the like abating deterioration in the structural layers such as corrosion of reinforcing steel. The geocomposite layer is bonded to and conforms to the structural layer, thus reducing reflective, shrinkage and fatigue cracking and increasing the structural capacity of the road or bridge.
