An improved sealant packaging and method for use with sealing joints and cracks in pavement and parking lots is provided. Liquid sealant material is poured by volume into a container draped with a sheet. Container is cooled so that the sealant becomes a solid block, with the sheet adhered to the sides of the sealant block such that the sheet forms a container for the sealant. The sheet also acts a release liner for easily removing the sealant block from the container. Two or more contained blocks are stacked together, forming a package of two or more blocks self-sealed by sheets. When the package is placed in a melting kettle, heat migrates through the spaces between the individual sealant blocks and allows the smaller sealant blocks to melt quickly and evenly. Sheet and film melt with sealant material and are incorporated therein to form the final sealant product.

A paving system for paving or flooring includes a top layer of a plurality of paving elements, and an underlayment support layer of a polymeric material configured into panels. The panels are suitable to support the paving elements, the panels having a generally planar support surface.

The present invention relates to a semi-rigid pavement comprising: an upper course comprising upper course aggregate and a hydrocarbon binder; a support layer comprising chemically-stabilised aggregate, the support layer located below the upper course; and a subgrade, the subgrade located below the support layer; wherein a geosynthetic is at least partially embedded in the chemically-stabilised aggregate that comprises the support layer.

Formwork, matrices, concrete matrices and methods of manufacture are described. The formwork may be configured to receive and retain concrete within an internal void space and has a concrete free external void space. Also described is a concrete matrix formed using the formwork and related methods of manufacture of a formwork matrix and formwork. The formwork itself and matrices formed from the formwork may have a degree of compressive strength. With concrete poured and set into the formwork, the resulting concrete matrix has a very high compressive strength and forms a structural matrix on which a hardscape or load may be placed. The above formwork, matrices, and methods reduces the number of parts needed to form a formwork or matrix and may facilitate snap fit design and installation and hence the ability to assemble the matrix toolessly.

A method of producing an arrestor bed for slowing an aircraft overrunning a runway, including paving an area immediately beyond the end of a runway with foamed glass aggregate to define a bed, and covering the bed with a layer of cementitious material to define a composite bed.

A sports field comprises a base structure and a cover. The cover is at least partly permeable to fluid, especially water. The base structure comprises voids for containing fluid. The base structure forms a substantially continuous deck supporting the cover. The cover comprises or is formed by an artificial sports layer, such as artificial grass. At least a number of the voids are in fluid communication with each other. Wick elements are provided fluidly connecting at least a number of the voids with the cover for supplying fluid from the voids to the top layer.

A permeable paver and modular light system for making a parking space or a traffic lane using at least one replaceable lighting module or a plurality of replaceable lighting modules, wherein the replaceable lighting module or the plurality of replaceable modules have at least one power supply and at least one light source. The permeable paver and modular light system have a controller configured to turn on and off the replaceable lighting module individually or as a group, change a color of the replaceable lighting module individually or as a group, illuminate a configuration of the replaceable lighting module individually or as a group based on a stored configuration, and change the illuminated configuration of the replaceable lighting module individually or as a group. The permeable paver and modular light system have a plurality of permeable pavers to form a surface for supporting a load of a vehicle.

A water storage structure includes an impermeable layer including a plurality of hydrophobic particles, a water retentive layer provided on the impermeable layer and capable of holding a predetermined volume of liquid, and a pavement layer provided on the water retentive layer and including a tube penetrating from a first surface to a second surface.

Described herein are various examples of stackable interlocking support blocks formed of rigid foam, for forming single- and multi-course support systems for assembling hardscape raised patios and/or stairs, and stair and patio systems including such support systems.
