There is provided a three vehicle train for the continuous cold in-place recycling of asphalt road surface, the train comprising a first supply vehicle containing both water and asphalt emulsion that is in fluid communication with the remaining vehicles; a second milling vehicle for removing a portion of the topmost layer of the road surface as aggregate and evacuating the aggregate via a system of conveyors to a third vehicle; and a third processing vehicle for screening the aggregate to a proper size, mixing the aggregate with cement, water, and/or asphalt emulsion under computer control into a slurry, and depositing the resulting slurry onto the previously milled asphalt road surface.

Disclosed are asphalt binder compositions and methods for making such compositions with pure sterol:crude sterol blends. The sterol blends improve various rheological properties.

A method includes determining a first temperature of paving material, determining a first location of a paving machine corresponding to the first temperature, determining a second temperature of the paving material, and determining a second location of the paving machine corresponding to the second temperature. The method also includes generating a paving material map based at least partly on the first and second temperatures, and the first and second locations. The method further includes causing at least part of the paving material map to be displayed. The displayed at least part of the paving material map including visual indicia indicating the first temperature and the second temperature.

A construction method for playground surfacing. The method of the present invention including the steps of: a) preparing in situ a mixture comprising 29-70% by weight of cork granules and 30-71% by weight of a polymeric binder, at room temperature; b) pouring the mixture obtained in step a) on at least one surface area; c) compacting the mixture to a thickness in the range of 35-135 mm and to a density in the range of 100-300 kg/m.sup.3; and d) curing the compacted mixture from step c).

A screed control system for a screed system includes a controller communicably coupled to a position sensor and at least one of a screed pressure assist system, an extendable screed height system, and a tamper system. The controller is configured to receive a signal indicative of a position of an at least one extendable screed with respect to a main screed. The controller is also configured to determine a change in the position of the at least one extendable screed with respect to the main screed. The controller is further configured to control at least one of the screed pressure assist system, the extendable screed height system, and the tamper system based, at least in part, on the determination.

A paving machine for spreading, leveling and finishing concrete having a main frame, center module, bolsters laterally movably, and a crawler track associated with respective aft and forward ends of the bolsters. A bolster swing leg for each crawler track supports an upright jacking column. A worm gear drive permits rotational movements of the crawler track and the jacking column. A hinge bracket is interposed between each swing leg and a surface of the bolsters to enable pivotal movements of the swing leg. A length-adjustable holder engages the pivot pin on the hinge bracket and pivotally engages the swing leg. The holder permits pivotal motions of the swing leg in its length-adjustable configuration and prevents substantially any motion of the swing leg in its fixed-length configuration. A feedback loop cooperates with transducers keeping the crawler tracks position. The paving machine can be reconfigured into a narrowed transport configuration.

A asphalt pavement recycling device comprising a base frame hingedly secured to a platform, a rotatable drum unit rotatably secured to the base frame, the drum unit having a drum opening and a drum rear, a hopper assembly hingedly secured to the base frame, a burner assembly hingedly secured to the base frame wherein the burner is used to heat the materials which are to be recycled/processed, a fuel source, a plurality of right-handed flights secured within the rotatable drum unit, a plurality of left-handed flights secured within the rotatable drum unit, a plurality of gator plates secured within the rotatable drum unit, a hydraulic unit secured to the device and operationally associated with the base frame, the rotatable drum unit, the hopper assembly and the burner and a control station operationally associated with the hydraulic unit, the base frame, the rotatable drum unit, the hopper assembly and the burner.

A road paver includes a screed assembly for laying a mat of paving material, and a tank for storing a coolant. The road paver further comprises a nebulizer device configured to receive the coolant from the tank and to nebulize the coolant into a coolant fog in an environment of the road paver. By cooling the environment of the road paver, the amount of harmful fumes emitted by hot paving material can be substantially reduced.

A display unit for a road machine includes a display and processing circuitry. The road machine includes a tractor, a hopper installed in front of the tractor to receive a paving material, a conveyor configured to feed the paving material in the hopper to the back side of the tractor, a screw configured to lay and spread the paving material fed by the conveyor behind the tractor, a screed configured to lay and level the paving material laid and spread by the screw behind the screw, and an information obtaining device configured to obtain information on road pavement. The processing circuitry of the display unit is configured to predict a future event based on the information on the road pavement obtained by the information obtaining device, and to display information on the event on a road map on the display.
