FLOORING ELEMENT
20220112725 · 2022-04-14 ·

A flooring element suitable for connection to other elements in a flooring system. The flooring element comprises a body, a female connector and a retainer. The body defines a connector surface that is horizontal when in use. The female connector comprises a connector recess which is suitable for receiving a male connector and also which defines a connector opening in the connector surface. The retainer is connectable to the body such that, while it is connected to the body, the retainer is movable between and open position and a closed position. When in the closed position, the retainer is arranged to restrict movement of the male connector to guard against the male connector exiting the connector recess through the connector opening. When in the open position, the retainer does not restrict movement of the male connector thereby permitting the male connector to exit the connector recess through the connector opening.

Polymer panels for walkway and paving

Embodiments provide a polymeric walkway for mitigating surface water runoff and a method for constructing the same. A polymeric walkway module is secured to a pre-conditioned ground. The polymeric walkway module includes an upper panel, a lower panel, and a plurality of spacers. The upper panel includes a plurality of perforations. The plurality of spacers is positioned between the upper panel and the lower panel defining a hollow space. Surface water permeates through the plurality of perforations and occupies the hollow space during the surface water runoff.

HIGH-FRICTION ROAD PATCH
20220098801 · 2022-03-31 ·

A high-friction road patch may comprise an aggregate capable of providing sufficient friction between a road surface and vehicle wheel. In some embodiments, the patch may comprise a waterproof, asphalt overlay with a first layer of cured bitumen and calcined bauxite aggregate particles, a second layer of viscous bitumen and a reinforcement component, and a binder layer for bonding the overlay with the road surface. The resulting product may provide a sufficient skid resistance value in an overlay that is far less susceptible to or incapable of debonding as with prior art solutions.

INTERLOCKING PAVING BRICK ASSEMBLY
20220064871 · 2022-03-03 ·

An interlocking paving brick assembly comprises a protruding brick (10) and a recessing brick (20). The protruding brick is a block and comprises a first top portion (11) and four first sidewalls (12). Every angle between each of the first sidewall and the first top portions is a right angle, each of the first sidewall comprises a tenon structure (13). The recessing brick is a block, including a second top portion (21) and four second sidewalls (22). Every angle between each of the second sidewall and the second top portions is a right angle, and each of the second sidewall comprises a mortise structure (23). The tenon structure of the protruding brick and the mortise structure of the recessing brick is structurally complementary to each other, so the protruding brick and the recessing brick can be connected by the tenon structure and the mortise structure to form the interlocking paving brick assembly.
