A process for making a layered multi-material structural element having controlled mechanical failure characteristics. The process includes the steps of: supplying a cementitious layer and forming a polymer layer on the cementitious layer by additive manufacture such that the polymer layer has a first thickness and the cementitious layer has a second thickness, wherein the polymer layer comprises a polymer and the cementitious layer comprises a cementitious material; and allowing the polymer from the polymer layer to suffuse into the cementitious layer for a period of time to obtain a suffused zone in the cementitious layer such that the suffused zone has a third thickness that is less than half the second thickness.

A method of installing a binder-based overlay system may include contacting a layer of geotextile fabric to a surface of a substrate and applying a primer layer to a surface of the geotextile fabric. Two or more binder layers including infill particles may be applied over the primer layer. A resurfacer layer followed by one or more color layers may be applied over the two or more binder layers. The primer layer, one or more binder layers, resurfacer layer, and two or more color layers may cure upon application to form a monolithic layer upon the substrate.

A pavement repair system is provided utilizing solid phase auto regenerative cohesion and homogenization by liquid asphalt oligopolymerization technologies. The system is suitable for use in repairing asphalt pavement, including pavement exhibiting a high degree of deterioration (as manifested in the presence of potholes, cracks, ruts, or the like) as well as pavement that has been subject to previous repair and may comprise a substantial amount of dirt and other debris (e.g., chipped road paint or other damaged or disturbed surfacing materials). A system utilizing homogenization by liquid asphalt oligopolymerization is suitable for rejuvenating or repairing aged asphalt, thereby improving properties of the paving material.

A composite structure having a solid-phase concrete base-substrate component; a fibrous component that is a plurality of polypropylene fibers embedded into and thereby mechanically attached to the solid-phase concrete base-substrate component, wherein the fibers extend from within the concrete base-substrate component and out of the concrete base-substrate component through an exterior surface of the concrete base-substrate component; a polyvinylchloride-adhesive layer component having a first and second surface, wherein the polyvinylchloride-adhesive layer component first surface is in contact with and adhesively attached to the fibrous component, and wherein the polyvinylchloride-adhesive layer second surface is in contact with and adhesively attached to a first surface of a polyvinylchloride or polyvinylchloride-alloy interior sheet; and a polyester reinforcing component having a first and second surface, wherein the polyester reinforcing component first surface is in contact with a second surface of the polyvinylchloride or polyvinylchloride-alloy interior sheet, and wherein the polyester reinforcing component second surface is in contact with a first surface of a polyvinylchloride or polyvinylchloride-alloy exterior sheet.

A method for producing a floor construction on a substrate by applying a screed to the substrate and then applying a seal to the screed. The screed is based on a screed composition which includes an aluminate binder, a calcium sulfate binder and fillers, where the amount of filler is 30 to 80 wt % and the total amount of aluminate binder and calcium sulfate binder is 20 to 70 wt % and the weight ratio of aluminate binder to calcium sulfate binder is in the range from 1:1 to 1:5. The method enables a short production time and at the same time improved adhesion between screed and seal.

A bituminous composition is used as an adhesive binder. The bituminous composition has at least one acidic additive of general formula (I): R(COOH)z in which R is a linear or branched, saturated or unsaturated hydrocarbon-based chain having from 4 to 68 carbon atoms, preferably from 4 to 54 carbon atoms, more preferentially from 4 to 36 carbon atoms and z is an integer ranging from 1 to 4, preferably from 2 to 4.

A composite structure having a solid-phase concrete base-substrate component; a mesh component having non-woven solid-phase polymeric strands that are fused together to form a three-dimensional structure having a thickness of at least three millimeters, the thickness being defined as the greatest normal distance between the mesh-component first side and second opposing side, at least a portion of the polymeric strands that make up the mesh-component first side are embedded into and thereby attached to the solid-phase concrete base-substrate component; a substantially planar component having first and second sides, wherein the substantially planar-component first side is attached to the mesh-component second side; and an adhesive-layer component having a first and second surface, wherein the adhesive-layer component first surface is in contact with and attached to the second side of the substantially planar component, and wherein the adhesive-layer second surface is in contact with and attached to a first surface of a polyvinylchloride or polyvinylchloride-containing exterior sheet.

A fire resistant building panel comprising: a first major face; a second major face; and a fire resistant body comprising a binder, at least one additive, and at least one fiber material, wherein the binder comprises a calcareous material and a siliceous material; and wherein the fire resistant body is disposed between the first major face and the second major face. The fire resistant body provides a fire rating of at least 45 minutes as tested in accordance with Australian Standard AS1530.4-2005.
