Disclosed herein are formulations for, and methods of making and using compositions formulated through the use of maltenes to lower the required asphalt emulsion content for recycling and stabilization of roadway materials as herein disclosed

A plastic multipurpose component that is suitable as a building block and is filled with filling bodies is used to form a sheet-like assembly from a plurality of components. The multipurpose component has double-walled outer frame parts (2) with an outer frame wall, an inner frame wall and a tread surface connecting them, at least one coupling device (6, 8) for connecting two adjacent components being provided on each of the outer lateral surfaces thereof. Where appropriate inner walls (4) divide the interior of the outer frame (2) formed by outer frame parts into a pattern of cellular lead-throughs (6). Inner bottom support frames (11), and where appropriate, bottom transverse struts on the double-walled outer frame and inner frame serve for stabilizing and supporting at least one filling body introduced in the plastic multipurpose part.

A modular cell that may be used with other cells to form a matrix under a load bearing feature, the cell being a single piece molding that supports a compressive load placed thereon, the molding including a void space defined within: a skirt shaped support member defining a substantially planar surface with an opening therein; and at least one leg integral to and extending from the support member. The cell further includes at least one separate linking member that releasably links together multiple cells to form a matrix of cells. The cells may be linked together vertically and/or horizontally. The cell and matrix include greater load bearing capacity and rigidity through aligned legs to carry the weight as well as interlinking members that act to share the load among the various cells. The design also requires less material hence is cheaper to produce. The void space is also easily accessed hence allowing for easy access, filling and laying of utility lines where needed.

A water-permeable woven geotextile fabric for providing soil reinforcement and/or stabilization, for example as an underlayment in road construction, utilizes a series of round warp fibers, in combination with a series of flat warp fibers, across the width of the fabric to increase water flow while still providing desired filtration. In particular, the round warp fibers form angles that allow greater amounts of water to pass through the fabric. In addition, using both round and flat warp fibers results in increased roughness of the fabric surface, which makes the fabric more resistant to being pulled out of the soil when pulled on. Furthermore, one or more of the round and/or flat warp fibers can include a color selected for high visibility to the human eye in daylight conditions.

A perforated geocell is made from a plurality of strips that form cells. Each cell wall has a single pattern of perforations spaced evenly over the cell wall. This avoids uneven distributions of stress over the cell wall, reducing deformation of the geocell.

A construction process for quickly and integrally replacing a damaged pavement slab without suspending flights of civil aviation is provided according to embodiments of the present application, including: a first stage: reinforcing a foundation of a damaged pavement slab by grouting; and a second stage: integrally replacing the damaged slab with early-strength and quick-drying concrete. The construction process of fast overall replacement of a damaged pavement slab in civil aviation non-suspend construction provided by the embodiments of the present application solves the limitations of the traditional pavement slab repair process well. The present application first reinforces the damaged pavement slab foundation through grouting construction to solve the problems of slab bottom vacancy, foundation settlement, and insufficient bearing capacity of the base layer; then uses the early-strength rapid-curing concrete suitable for rapid overall slab replacement of the pavement to carry out overall replacement construction for the damaged pavement slab.

An underlayment layer is configured to support an artificial turf assembly. The underlayment layer comprises a core with a top side and a bottom side. The top side has a plurality of spaced apart, upwardly oriented projections that define channels suitable for fluid flow along the top side of the core when the underlayment layer is positioned beneath an overlying artificial turf assembly.

The present invention relates to a road surfacing system, in particular an asphalt road, which comprises at least one main layer which is at least partially and at least in places permeable to liquids and gases for absorbing compressive and shear forces generated on the main layer by load bodies, for example vehicles, travelling and/or standing on the main layer, wherein the main layer is arranged on a drainage layer through which liquids and/or gases can flow, and further where-in the drainage layer is again arranged on top of a drainage layer which is arranged and intended to at least partially drain liquids from the road surfacing system passing through the main and drainage layers, characterized in that the main layer is substantially free from aggregates and instead is formed with adhering ball elements formed with a plastic and/or a metal.
