A textile-reinforced concrete road paving apparatus and a method of repairing concrete road pavement can minimize use of construction equipment by using the textile-reinforced concrete road paving apparatus integrally formed to consecutively cut concrete, dispose a reinforcement material, and construct a repaired cross section so as to reduce a construction period, thereby remarkably reducing construction costs. Further, a textile grid reinforcement material, which is a noncorroding reinforcement material, is applied to form the repaired cross section of the concrete road pavement so as to prevent concrete from being detached due to corrosion. Further, a textile reinforced grid is precisely disposed at a required position, and thus the thicknesses of the primary and secondary concrete pavement are precisely adjusted, and thus construction precision can be increased.

A concrete slab (20) comprises conventional concrete and a combined reinforcement of both post-tension steel strands (22, 26) and fibres (29). The post-tension steel strands (22, 26): —have a diameter ranging from 5 mm to 20 mm, —have a tensile strength higher than 1700 MPa. The fibres (29) are present in a dosage ranging from 10 kg/m.sup.3 to 40 kg/m.sup.3 in case of steel fibres are in a dosage ranging from 1.5 kg/m.sup.3 to 9 kg/m.sup.3 in case of macro-synthetic fibres.

Structural cells and matrices using the structural cells for positioning below a hardscape that define a void space therein, the structural cells, matrices using the cells and methods of assembly allowing in one embodiment the introduction of a structural fluid such as concrete to provide an alternative structural cell and matrix product. In one embodiment a structural cell assembly is described comprising a structural cell with a plurality of legs integrally linked to a frame at a first frame end, the frame linking the legs together and the frame defining a generally flat plane with the legs extending substantially orthogonally away from the first frame end about the frame flat plane to a leg terminal end; and a separate plate engaging the legs, the separate plate comprising linked sockets, each socket engaging the leg terminal end; and/or linked sockets, each socket engaging the leg frame ends or a part thereof.

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.

A plurality of identical slab bolster uppers each include a body with a rebar contact surface separated a height distance from a ground contact surface along a vertical axis. The rebar contact surface extends from a first end to a second end along a horizontal axis. The first end terminates in a planar abutment surface that is one side of a thickness profile, and the second end has a different shape that includes a planar abutment surface, and a snap-fit connector shaped to receive the thickness profile of the first end. Two slab bolster uppers may be moved from a disconnected configuration to a connected configuration exclusively responsive to sliding the planar surfaces along one another while in contact along a vertical axis until the thickness profile of the one slab bolster upper is received in the snap-fit connector on the other slab bolster upper.

An edge protection system for use with concrete flooring, including a first part for coupling to an edge portion of a first concrete flooring panel and a second part for coupling to an opposed edge portion of a second, neighbouring, concrete flooring panel, a dowel plate and a dowel sheath, wherein the dowel plate is for supporting the second concrete flooring panel relative to the first concrete flooring panel, the dowel sheath is fitted to extend laterally from the first part, with an internal cavity of the dowel sheath aligning with apertures formed in the first and second parts such that the dowel plate is able to be inserted into the dowel sheath cavity through said apertures to a supporting position in which the dowel plate remains in the apertures and extends laterally from the second part.
