Particulate infill from a worn down infilled artificial turf, particularly a sand/rubber mixture which includes crumb rubber from vehicle tires, is extracted from a prior field and then thereafter incorporated into the top surface of the compacted base at the same site, thereby to assure better drainage conditions in the compacted base for the subsequently installed field. The extracted and incorporated infill helps to maintain open drainage channels throughout the top of the compacted base, particularly in areas where limestone is prevalent. Otherwise, the limestone “fines” are susceptible to compacting and creating a cement-like crust at the top of the base. An existing infill extractor/collector device is modified to operate in a second mode, so that instead of merely performing the conventional bagging of the already-used infill, the already-used infill is laterally diverted back on to the base at the same site, and thereafter, distributed and tilled into the base. By incorporating the extracted infill into the base of the new field, the need to bag, remove, and dispose of the used infill is eliminated, along with the time and costs associated therewith, while at the same time improving the drainage of the new field. Two structures for diverting the collected infill are disclosed.

A road finishing machine is described having a screed embodied or configured to produce a road pavement and having a heating device with multiple heating elements. The road finishing machine may furthermore include at least one generator for supplying the heating device with electrical power. The road finishing machine moreover has a controlling system embodied or configured to activate the generator. The heating elements each have at least one temperature sensor employed for detecting a malfunction occurring thereat. The disclosure furthermore relates to a method for detecting a malfunction of a heating element installed within a screed of a road finishing machine.

A paving machine includes a mold coupled to a telescopic frame member, by which the mold side-shifts relative to a main frame. A tight clearance between the paving machine and a surface being paved may be achieved by the ability to side-shift the mold. The paving machine may also include a number of vibrator motors. A flow to the vibrator motors may be controllable by a manifold controller. The manifold controller is located on an end of the telescopic frame member. By locating the manifold controller on the telescopic frame member, an operator of the paving machine may both stand on the telescopic frame member to watch the paving mold and adjust the settings of the vibrator controller. This is advantageous in allowing the operator to achieve proper concrete consolidation by visual feedback without leaving the telescopic frame member.

An apparatus for screeding concrete to produce a level finished surface includes a frame assembly having a front end and rear ends and a pair of spaced vertically oriented stabilization legs supporting a generally horizontal front member. An extendable boom assembly is provided having front and rear ends, and an exterior boom section pivotably secured to the frame assembly proximate said rear end. The extendable boom assembly is also adjustably mounted on said front member to allow generally lateral motion of the boom.
