A coating applicator vehicle is configured to selectively discharge a flow of liquid emulsion and aggregate onto a roadway. The vehicle includes a rolling chassis and a powered spraying assembly supported by the chassis. The spraying assembly includes a strainer enclosure and a strainer basket that cooperatively define a manifold axis along which the strainer basket is manually slidable into and out of a passage of the enclosure.

A system for re-surfacing a pavement surface includes a conduit configured to transfer a spreadable material and a material application and dispersal device (MADD) coupled in flow communication with the conduit. The MADD includes at least one material application mechanism (MAM) coupled in flow communication with the conduit. The system also includes a pressurization device coupled in flow communication with the conduit and the MADD. The pressurization device is configured to channel the spreadable material into the at least one MAM and to generate a positive pressure within the at least one MAM to facilitate delivering the spreadable material to the pavement surface.

An example operation includes one or more of shaping vertical edges of wet concrete using concrete finishing edger tool, wherein the concrete finishing edger tool comprises a rounded shaping element portion with a radius from around inch to around 1 inch, a tang, and a handle, wherein the vertical edges are shaped prior to the removal of a form surrounding the concrete.

A paving machine that comprises a frame, a driving mechanism coupled to the frame, an asphalt delivery system, a spray assembly coupled to the frame, a pump coupled to the spray assembly, a screed coupled to a back side of the frame and configured to smooth asphalt material applied to the road, and a controller coupled to the driving mechanism.

A paving machine which includes a containment basin. The containment basin has at least one brush therein to spread paving material onto a roadway surface.

A road processing machine may include a frame having a leading end and a trailing end. The machine may also include a first spray bar located at one of the leading end or the trailing end. The first spray bar may be configured to distribute a first material onto a road over which the road processing machine is traveling. The machine may also include at least one of a second spray bar or a broadcast spreader located at one of the leading end or the trailing end opposite the first spray bar. The at least one of the second spray bar or the broadcast spreader may be configured to distribute a second material onto the road. The machine may further include at least one processing tool located between the leading and trailing ends of the frame and being configured to process a material of the road.

A method of processing a primitive road is disclosed. The method may include towing a groomer, directing a primary material from the groomer onto a surface of the primitive road, and disrupting the surface of the primitive road to loosen road material with at least a first processing tool onboard the groomer. The method may also include mixing the road material with the primary material using the at least a first processing tool, compacting the mixed road material and primary material with a second processing tool onboard the groomer, and directing a sealing material from the groomer onto a compacted surface of the primitive road.

In some implementations, a liquid dispersal system of a compactor machine may obtain configuration information that indicates a quantity of rotations of a compaction element of the compactor machine in association with a dispersal cycle and that indicates a percentage of the dispersal cycle. The liquid dispersal system may determine, based on the configuration information and sensor information, a first time interval of the dispersal cycle and a second time interval of the dispersal cycle. The liquid dispersal system may cause activation of one or more liquid pumps of the liquid dispersal system in accordance with the first time interval. The liquid dispersal system may cause inactivation of the one or more liquid pumps in accordance with the second time interval.

A drone includes a body frame and a plurality of boom assemblies. Each boom assembly has a proximal end region disposed at the body frame and a distal end region linearly displaced from the proximal end region. Each propulsion member of a plurality of propulsion members is disposed at the distal end region of one respective boom assembly, and includes a motor and a propeller. When the drone is operated to fly above a concrete surface, the plurality of propulsion members are energized to apply lift to the drone. A fluid tank is disposed at the body frame. A spray bar including a plurality of spray nozzles in fluid communication with the fluid tank is disposed at a lower portion of the body frame. A fluid pump is configured to actuate the plurality of spray nozzles to spray a fluid from the fluid tank onto the concrete surface.
