Abstract
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.
Claims9
Pavement (11) formed by a set of concrete slabs (13) with an H thickness, characterized by:
- each of these slabs (13) has several superficial grooves (15, 17) of an H3 height delimiting sub-slabs (21);
- comprises, as reinforcement, of a set of tie bars (25, 27;
- 26, 28) of sub-slabs (21) adjacent to both sides of these superficial grooves (15, 17) that are arranged under them at an H2 distance,
- H2+H3 is less than H/2 and the H1 distance between tie bars (25, 27;
- 26, 28) and half the H thickness of the slabs (13) is of sufficient magnitude so that sub-slabs (21) can transmit negative bending moments between them
- wherein the tie bars (26, 28) are bars successively arranged on one side and then on the other side of superficial grooves (15, 17);
- and
- the slabs (13) form a convex curvature outside the sub-slabs (21) on which the load acts.
