Abstract: A concrete paver system with a reconfigurable hydration system which utilizes a plurality of individually flow controllable spray nozzles, which are clamped on support structures, which also support objects being dragged across a top surface of concrete which is being finished. The plurality of flow controllable spray nozzles being configured to be moved about said hydration system so as to change a pattern of water vapor application, all without the use of tools.

Abstract: An HMA plant which uses combination direct exhaust heated and indirectly steam heated pre-heating drum in combination with a sealed indirect hot oil heated rotary shaft mixer, where the steam given off from the heated HMA is maintained, separated from the sulfur containing exhaust of a hot oil heater, so as to minimize the production of acid in liquid form.

Abstract: A work vehicle including an engine and a transmission operatively engaging the engine. The transmission has at least one input shaft and at least one output shaft, wherein a ratio of a rotational speed of the output shaft with respect to a rotational speed of the input shaft may be changed by said transmission. The work vehicle further includes a cutter drum operatively engaging said transmission and a controller, wherein the controller selects the transmission ratio based on an input of a user of the work vehicle.

Abstract: A concrete curing and texturing machine includes a truss frame supporting a reservoir of curing fluid and drive members positioned at the ends of the truss frame for powering the machine longitudinally along a roadway being surfaced. A texturing carriage is mounted to the truss frame and arranged to longitudinally move back and forth along the truss frame. A truss member is mounted rearwardly of the truss frame and includes a sprayboom carriage unit which moves longitudinally move back and forth along the truss member. The sprayboom carriage unit supports a sprayboom having a plurality of nozzles operatively connected to the liquid reservoir.
