A system and method for the application of friction-modifying coatings to roadways, walkways, pathways and other areas subject to vehicular, human or animal traffic, the system and method comprising the controlled, simultaneous application of binder and filler to a surface of a substrate, using a mobile device which passes over the substrate as the binder and filler are being applied. The system includes a mobile platform configured for being coupled to a vehicle. A binder applicator is mounted on the mobile platform and includes an array of spray nozzles coupled to a resin container. An air knife is mounted on the mobile platform and coupled to an air compressor for generating an air curtain. An aggregate dispenser bar including at least one aggregate dispenser is coupled to an aggregate bin and mounted on the mobile platform for dispensing aggregate.

Systems and methods for applying roadway surface treatments. The system has an aggregate application assembly and a resin application assembly that are mounted or otherwise secured to a truck or other vehicle. The resin application assembly is spaced from the aggregate application assembly in the direction of travel of the vehicle. As the vehicle moves along a roadway surface, the resin and aggregate can be continuously applied such that the aggregate is provided to portions of the roadway surface that have been covered with resin.

Method for evaluating of a quality of a generated pavement or a generated surface, generated by use of a construction machine, especially a road construction machine, road finishing machine or milling machine, having the following steps: receiving sensor values from one or more sensors and/or a sensor system of the construction machine; determining a specific sensor value combination within the sensor values, the specific sensor value combination being assigned to a specific quality situation; and outputting an operator message dependent on the specific quality situation.

A method of controlling spread pattern of a particulate material broadcasted by a spinner spreader involves permitting particulate material to flow through a plurality of sluices situated in a particulate material path between a bin and a rotatable disc of a spinner spreader. Each sluice receives a portion of the particulate material and delivers the portion of particulate material to a radial and/or angular position on the rotatable disc. The radial and/or angular position on the rotatable disc to which the portion of particulate material from at least one of sluices is delivered is adjusted by longitudinally translating the at least one independently moveable sluice independent of all other sluices of the plurality of sluices to change position of the at least one independently moveable sluice relative to the rotating disc thereby changing the spread pattern of the particulate material broadcasted by the rotatable disc.

An apparatus for spreading particulate material has a bin for holding particulate material, a rotatable disc for broadcasting the particulate material to a ground surface, a conveyor for conveying the particulate material in a particulate material path from the hopper to the rotatable disc, and a plurality of sluices situated in the particulate material path between the bin and the rotatable disc. Each sluice receives a portion of the particulate material and delivers the portion of particulate material to a radial and/or angular position on the rotatable disc. At least one of the sluices is independently moveable to adjust the radial and/or angular position on the rotatable disc to which the portion of particulate material from the at least one independently moveable sluice is delivered.

There is a hopper having a substantially closed interior space that is configured to receive a binder, a fill assembly that is configured to be in fluid communication with the interior space of the hopper, and an exit port. Secured to the hopper is a base with at least one carrier. A pneumatic pump is secured to the hopper. An ingress pipe is secured to be in fluid communication with the pneumatic pump. A valve housing is secured to the ingress pipe and the exit port of the hopper. A valve is secured within the valve housing. An egress pipe is secured to the valve housing, and a spreader bar is secured to the egress pipe.

A dry-bulk tanker for the provision of binding agents for soil stabilization for a spreading device comprises a storage container (10) for binding agent. A mechanical conveying device (18) for conveying binding agents from the storage container (10) into an intermediate chamber (20) is connected to the storage container (10). A pneumatic conveying device (36) for conveying the binding agent to the spreading device is connected to the intermediate chamber (20). A pressure relief device (40, 41) is connected to the mechanical conveying device in order to avoid the entry of compressed air into the storage container (10). The invention furthermore relates to a conveying system for a dry-bulk tanker and to a work train for working soils with a self-propelled ground working machine and a dry-bulk tanker.

A paving train for producing at least one pavement layer on a traffic surface is formed from at least two independently driven units travelling in a group, such as a road finisher, a road paver, an IP finisher, a feeder, a supply unit or the like. The units move one behind the other at a given distance. In order to enable communication between the units via certain parameters such as speed, material filling level and the like, and in order also to easily control a corresponding distance between the units as well as the corresponding material transfer, a wireless communication link is formed between the units at least for exchanging speeds and/or material filling level.
