The invention provides a pavement (11) formed by an assembly of concrete slabs (13) of thickness H, each slabs (13) comprising a plurality of superficial grooves (15, 17) of height H3, delimiting sub-slabs (21) and, as reinforcement, an assembly of tie bars (25, 27; 26, 28) for tying adjacent sub-slabs (21) on either sides of said superficial grooves (15, 17), the bars being disposed below the sub-slabs at a distance H2.

An array of anode assemblies for insertion at a plurality of locations in a gap between a section of a reinforced concrete structure and another solid structure is provided. Each anode assembly comprises an expandable member, an anode attached to the expandable member for protecting a steel reinforcement in the reinforced concrete structure, and an anode connector for interconnecting the array of anode assemblies. During use, each anode assembly of the array of anode assemblies is inserted into the gap, between the section of the reinforced concrete structure and the solid structure, at the plurality of locations. The expandable member of each anode assembly is configured to expand so as to press the anode into contact with a surface of the reinforced concrete structure.

A system which creates a durable seal between adjacent horizontal panels, including those that may be curved or subject to temperature expansion and contraction or mechanical shear. The durable seal system incorporates a plurality of ribs, a flexible member between the cover plate and the ribs and may incorporate a load transfer plate to provide support to the rib from below, and/or cores of differing compressibilities.

A concrete slab joint stabilizer including an expandable housing including a cylinder defining a slit running along its longitudinal length, the expandable housing having a housing axis extending longitudinally there through, and an expander configured to expand the expandable housing in directions perpendicular to the housing axis. The concrete slab joint stabilizer is configured to limit relative vertical displacement between two adjacent concrete slabs.

Described herein is a perforated tactile warning device comprising a tactile panel and a porous concrete slab. The tactile panel includes perforations to allow water to pass through the tactile panel and the tactile panel is secured to the porous concrete slab such that a space exists between the tactile panel and the porous concrete slab. Further, the porous concrete slab may include channels to collect water and direct water within the porous concrete slab. Further still, where the concrete slab includes channels, the concrete slab may be nonporous and may utilize drainage holes to permit water to pass through an otherwise nonporous concrete substrate.
