A ground stabilization grid which includes a series of polygonal shaped cells having x sides. The cells are formed by polymer walls having a wall height of between about 1 and about 6. Each cell shares a common wall section with at least two adjacent cells; and a majority of cells within the grid includes at least two reinforcing ribs extending across the cell to engage opposing walls of the cell. The reinforcing ribs are characterized by (i) engaging the cell walls between about 25% and about 75% of the wall height, and (ii) extending between different opposing walls of the cell.

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 water generation system for deserts is provided as a water generation system designed for desert climate areas and constructed in a surface pavement and generally includes a sand layer, which includes a water tank embedded therein and is covered with a moisture locking cloth on which a grading layer is laid. A water resisting cloth is arranged in the grading layer. Hollow water penetration tubes are arranged above the grading layer and have bottoms extending through the water resisting cloth and inserted into the grading layer with pouring and grouting of grout cement thereon to form a water pervious layer. As such, rainwater can be quickly conducted into the sand layer for storage for subsequent uses and air can be conducted into the grading layer to subject to condensation for forming condensed water on an undersurface of the water resisting cloth to achieve a purpose of automatic water generation.

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, a cementitious material, a water-impermeable sealing layer, and a containment layer. The structure layer has a first side and an opposing second side. The structure layer defines a plurality of open spaces. The cementitious material includes a plurality of cementitious particles disposed within the plurality of open spaces of the structure layer. The water-impermeable sealing layer is disposed along the first side of the structure layer. The containment layer is disposed along the opposing second side of the structure layer. The containment layer is positioned to prevent the plurality of cementitious particles from migrating out of the structure layer through the containment 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 for in-situ hydration includes a first layer, a second layer spaced from the first layer, and a cementitious mixture disposed between the first layer and the second 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 the water per unit area of the cementitious composite. M.sub.c is a mass of the cementitious materials of the cementitious mixture per unit area of the cementitious composite. x is 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. x is between 0.25 and 0.55.

A dry polymer cement overlay for trafficked pavement substrates (both asphalt and concrete). The dry polymer cement overlay is a thin overlay that can handle the load of traffic in a relatively short time and has a relatively long life cycle. Moreover, the dry polymer cement overlay can hold aggregate that is applied on the surface of dry polymer cement overlay before it cures in order to provide a friction surface. A stencil is used during application of a dry polymer cement layer to provide a patterned overlay that includes patterns separated by gullies. The patterned dry polymer cement overlay exhibits improved performance including short and long term substrate adhesion, reduced risk of delamination, safety through improved surface runoff and enhanced visibility, improved macro and micro friction, reflective crack management, and withstands higher deflections under heavy loads. The patterned dry polymer cement overlay may also reduce noise and improve aesthetics.

Detectable warning areas (DWAs) and methods of forming the same are provided. A mat template having one or more holes can be placed over a substrate, and a dome-forming material can be filled in the mat template by pouring the dome-forming material over the mat template and working the dome-forming material into the one or more holes of the mat template. The mat template can remain in place until the dome-forming material is completely cured, and then the mat template can be removed. DWAs formed according to this method display improved properties, including increased bond strength.
