A deck-slab waterproofing-membrane application brush for coating highway-bridge deck slabs with a waterproofing membrane, and a deck-slab waterproofing-membrane application apparatus for towing the brush to spread on waterproofing product are made available to enable the applying of deck-slab waterproofing membranes uniformly, safely, and efficiently to highway bridges. The deck-slab waterproofing-membrane application brush, for spreading on highway-bridge deck-slab waterproofing product, is characterized in that inside a furrow in a furrowed metal plate, numerous metallic bristles are aligned into rows in a packed, sheet-like form and fastened in a state in which the numerous metallic bristles are clamped.

A spraying device for introducing a fluid into the working chamber of a construction machine for processing the ground or road surfaces, comprises two fluid delivery apparatuses, a line system and a control unit. The present invention further relates to a construction machine, especially a recycler, a stabilizer or a cold milling machine, comprising such a spraying device and a method for operating such a spraying device.

A hand-held concrete edger is formed with a rectangular blade having a first, substantially planar part with an upper surface and a lower surface, and a second part extending substantially at a right angle from a long side of the first, substantially planar part, away from the lower surface. A handle extends substantially perpendicularly away from the upper surface of the first, substantially planar part and is configured with a spray device including a water supply and a sprayer, for spraying water onto an advance path of the edger. A control and vibration module is arranged on the upper surface of the substantially planar part and configured with a vibration element that vibrates the rectangular blade.

A float sprayer system for efficiently dispensing a fluid from a float to treat a curing material. The float sprayer system generally includes a float for smoothing a curing material and at least one sprayer on the float; with the at least one sprayer being adapted to dispense a fluid from the float. A pump is fluidly connected to the at least one sprayer by a conduit which extends through a handle that is connected to the float. The pump is adapted to transfer the fluid from the fluid source through the conduit to be dispensed by the at least one sprayer on the float. A valve on the handle may be utilized to control flow through the conduit within the handle, and a mobile device may be utilized to control the pump.

An adjustable paving machine includes a variably expandable portion. The variably expandable portion may be expandable laterally such as to accommodate paving operations of variable widths. The adjustable paving machine may be configured to spread a variety of paving materials on a paving surface, including oils, emulsions, asphalt, slurries, or the like. The adjustable paving machine may include a containment basin operative to contain a paving material such as to reduce lateral or longitudinal movement of the paving material. The adjustable paving machine may include an adjustable shoe configured to move the paving machine vertically relative to the paving surface. The adjustable paving machine may include one or more spreading elements configured to spread the paving material on the paving surface. The spreading elements may be supported by a spreading element support enabling easy replacement of the spreading elements.

A method for producing polyurethane flooring includes providing polyurethane reactive components including a isocyanate component and a polyol component, determining environmental data, determining process parameters for mixing the polyurethane reactive components, wherein the process parameters depend on the environmental data, mixing the foam for the polyurethane flooring by mixing the isocyanate component and the polyol component using a froth foam process with the process parameters, applying a first lane of the liquid foam to a ground, applying a second lane of the liquid foam to the ground, wherein a side edge of the second lane gets in contact with a side edge of the first lane, wherein the process parameter are determined so that the foam of the first lane is not cured before applying the foam of the second lane. Furthermore, the invention relates to an apparatus and a system for producing a polyurethane flooring.

This disclosure relates to an adjustable paving machine. In some examples, the adjustable paving machine includes a variably expandable portion. The variably expandable portion may be expandable laterally such as to accommodate paving operations of variable widths. The adjustable paving machine may be configured to spread a variety of paving materials on a paving surface, including oils, emulsions, asphalt, slurries, or the like.

The spreading elements may be supported by a spreading element support enabling easy replacement of the spreading elements.

A device movable across a road to level emulsion thereon. A wheeled frame includes brushes extending downward to engage the emulsion. A manual worm gear connected between the frame and a towbar assembly positions the towbar mount to connect to a vehicle hitch and vertically moves the frame while maintaining the brush contacting plane. Spring biased guide wheels position the brushes to contact the road surface even though the surface is uneven.
