A paving machine includes an engine, a material conveying system, a screed system including a plurality of screed heaters, and an emulsion sprayer system. The emulsion sprayer system includes an emulsion tank and one or more emulsion heaters. The machine further includes an engine load sensing system and a control system. The control system being configured to receive information from the engine load sensing system indicative of a load on the engine, and limit the operation of the one or more emulsion heaters when the received information indicates the load on the engine is above a value.

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 frame coupled to a vehicle. A binder applicator is mounted on the frame and includes an array of spray nozzles coupled to a resin container. An air knife is mounted on the frame 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 frame for dispensing aggregate.

A spreading device is disclosed for spreading vehicles for discharging spreading agents. The spreading device includes at least one tank for receiving liquid spreading agents to be spread and at least one rotationally-driven discharge device, connected via a provided supply unit to the tank. The discharge device has at least one base body and one cover securely connected to the base body, wherein the base body defines a receiving chamber (AR) for the supplied liquid spreading agent and is in the shape of a cylinder. The base body has at least one bottom section, forming an underside (U) of the discharge device, with an inlet opening and at least one wall section projecting from the bottom section and concentrically surrounding an axis of rotation (RA). The discharge device has multiple discharge units, each having a discharge opening, for dispensing the liquid spreading agent from the receiving chamber (AR).

A reconfigurable modular hopper spreader assembly is mountable in the bed of a truck and includes a modular dual-wall hopper with a receptacle for storing solid material to be spread onto the ground and with individual liquid chambers for storing a liquid or different liquids to be sprayed onto the ground. The hopper spreader assembly further includes a fluid conduit for filling or draining the liquid into or out of the liquid chambers, a liquid pump fluidly connected with the liquid chambers for drawing the liquid from the liquid chambers, a selector valve fluidly connected with the fluid pump for directing the liquid drawn from the liquid chambers, and a liquid dispenser fluidly connected with the selector valve for distributing the liquid onto an application area.

A method of resurfacing exposed surfaces of existing roads, and a resurfaced road. The method may include forming stress absorbing membrane interlayers (SAMIs) over the exposed surface of the existing road. The SAMIs may include a first layer of a binding material and a fiber material. The method may also include disposing an asphalt mixture directly over the SAMIs. The disposed asphalt mixture may cover the SAMIs. Additionally, the method may include shaping the asphalt mixture disposed over the SAMIs.
