The disclosure relates to a road finishing machine comprising a paving screed for the production of a new road pavement layer of a paving material and a unit provided on the road finishing machine to generate a dynamic compacting specification field based on thermographic geosignals with regard to at least one temperature image that exists behind the paving screed of the road finishing machine for at least one surface section of the newly installed road pavement layer. An information indication unit provided on the road finishing machine is configured to display at last one compacting message that is at least partially based on the compacting specification field to an operator of at least one compacting vehicle that follows behind the road finishing machine for compacting of the newly installed road pavement layer.

A wearable computer is used for monitoring process data in road finishing. The wearable computer receives process data of the road finishing process. In the event of process data lying outside a predetermined range, the wearable computer effects alerting of the wearer of the wearable computer.

A cementitious composite includes a first layer, a second layer, and a cementitious mixture disposed between the first layer and the second layer. The cementitious mixture includes (i) cementitious materials and (ii) a viscosity modifier and/or an accelerator. The cementitious materials provide a void fraction between 0.64 and 1.35. The void fraction is defined as the ratio of the volume of the voids within the cementitious mixture per unit area of the cementitious composite to the volume of the cementitious materials per unit area of the cementitious composite. The cementitious mixture is configured to absorb a mass of water that provides a maximum 28 day compressive strength of the cementitious composite. A ratio of the mass of the water relative to the mass of the cementitious materials of the cementitious mixture per unit area of the cementitious composite that provides the maximum 28 day compressive strength of the cementitious composite is between 0.25 and 0.55.

A safety surface with an engineered shock-absorbing base. The base may include one or more engineered resilient mats. The mats may be fabricated of repurposed tire rubber. The mats may be adjoined edgewise. Adjoined mats may be coupled together. The base may overlay a surface. The base may include upward-facing pockets. Interiors of the pockets may receive loose fill. An upper layer may cover the base. The upper layer may bond to the base. The upper layer may seal the loose fill within the safety surface. The upper layer may include poured-in-place surfacing. The upper layer may be textured. The upper layer may include synthetic turf. Impact upon the upper layer may be attenuated by flexion of the base. Mats may be coupled without hardware fasteners. Exterior surfaces of pockets of one mat may be nested into complementarily contoured features of an adjoining mat.

Systems and methods of imprinting concrete having exposed aggregate. The imprinted concrete system comprises a concrete layer, an imprinted layer disposed on the concrete layer, wherein the imprinted layer comprises a decorative aggregate, and has been imprinted with an imprinting tool. In some embodiments, the decorative aggregate may be at least partially exposed.

A system and associated method constructs a building material from lunar soil. A magnetic sorter magnetically sorts the lunar soil and the system creates a layered surface comprising a microwave susceptible, thermal conductive top layer of lunar soil and a poorly microwave-susceptible and poorly thermally conductive sublayer of lunar soil. A microwave generator generates microwave energy into an antenna and directs the microwave energy onto the top layer of lunar soil to sinter the microwave susceptible, thermal conductive top layer of lunar soil.

An artificial turf system utilizing a surface stabilization grid. The grid includes (i) a plurality of closed cells having a wall height, with each cell sharing a common wall section with at least two adjacent cells, and (ii) substantially each cell includes at least one reinforcing rib extending across the cell to attach to opposing walls of the cell. A cementitious load bearing material fills substantially all the cells of the grid, a layer of drainage fabric is positioned over the stabilization grid, and an artificial turf is positioned over the layer of drainage fabric.

Detectable warning areas (DWAs) and methods of forming the same. A dome-forming material can be mixed with a catalyst to form a mixture, which can then be poured into a dome-shaped cavity of a die-cast mold or a reusable mat template with a grommet. A peg may be inserted into the mixture. The mixture may be allowed catalyze and harden.

A cementitious composite includes a first layer, a second layer spaced from the first layer, a cementitious mixture disposed between the first layer and the second layer, and a structure layer disposed between the first layer and the second layer. The cementitious mixture is disposed within the structure layer. The cementitious mixture includes cementitious materials. The cementitious mixture is configured to absorb a mass of water that provides a maximum 28 day compressive strength of the cementitious composite upon curing which is represented by M.sub.w=x.Math.M.sub.c. M.sub.w is the mass of water per unit area of the cementitious composite. M.sub.c is a mass of cementitious materials of the cementitious mixture per unit area of the cementitious composite. x is a ratio of the mass of water relative to the mass of cementitious materials of the cementitious mixture per unit area of the cementitious composite. x is between 0.25 and 0.55.

A cementitious composite includes a structure layer, cementitious material, a first layer, and a second layer. The structure layer defines a plurality of open spaces. The cementitious material is disposed within the plurality of open spaces of the structure layer. The first layer is disposed along a first side of the structure layer. The second layer is disposed along an opposing second side of the structure layer. The second layer is positioned to prevent at least a portion of the cementitious material from migrating out of the structure layer.
