摘要： A device and method for using microwave heating to repair defects in bitumen surfaces. The device identifies a defect in a bitumen layer and divides a region around the defect into a primary heating zone and a secondary heating zone. Microwaves transmitted through waveguides arranged over the primary and secondary heating zones heat the bitumen layer in each zone such that the temperature of the primary heating zone is always 20° C. higher than the temperature of the secondary heating zone. After heating the bitumen layer around the defect, the defect is filled with a pre-heated bitumen mixture compacted until a top surface of the pre-heated bitumen mixture is level with an original surface of the bitumen layer.

摘要： A mobile volumetric concrete mixing system includes a suction system that vacuums up trench spoils while a trench is being cut. These trench spoils are then screened on-site for particle size to be reused and mixed with water, cement, and/or other admixtures at an auger mixer to form a backfill mixture. This backfill mixture may then be loaded into a hopper that continuously agitates the mixture so that the mixture does not harden before pouring. The agitating hopper is coupled to a discharge chute of the auger mixer and includes one or more augers disposed at various orientations that the backfill mixture is channeled through. From the agitating hopper, the backfill mixture is channeled to an applicator that moves along the trench and that enables the mixture to be quickly poured into the trench with little clean-up required.

摘要： An apparatus for in-place recycling of materials that form part of a roadway pavement with agglomerated aggregates in a bituminous composition, includes a load-bearing structure suitable for driving on the pavement in a direction of travel and carries, from the front to the rear in the direction of travel, a transverse milling machine for milling the pavement to a defined depth and width to produce milling debris, a mixing device for mixing the milling debris with a binding composition, and a spreading sub-assembly for distributing the milling debris/binding composition mixture across the milled pavement. The apparatus further includes a crusher with blades, between the milling machine and the mixing device, open on the bottom, for crushing the milling debris. In one embodiment, the crusher and the mixing device are located in a single unit. The application also relates to a crusher for milling debris from roadway pavements.

摘要： A machine includes a material working mechanism movable relative to a frame to vary working depth of the material working mechanism. A control system monitors certain parameters, and controls a liquid dispensing mechanism to control application of a liquid such as water or an emulsion to be applied to material being worked by the material working mechanism based upon the parameters. The control system functions to produce a desired proportion of the liquid such as a liquid percent density in worked material.
