    摘要： 1. A CONTINUOUS METHOD FOR FORMING A SUBSTANTIALLY WATER IMPERMEABLE PLASTIC FOAM STRUCTURE USEFUL IN FROST BARRIER AND THERMO-INSULATION CONSTRUCTIONS COMPRISING: A. MIXING PARTICLES OF A FOAMABLE THERMOCOLLAPSE RESISTANT PLASTIC MATERIAL WITH A LIQUID BINDER HEATED SUFFICIENTLY TO CAUSE SAID PARTICLES TO FOAM, SAID HEATED BINDER SUBSTANTIALLY UNIFORMLY COATING THE OUTSIDE SURFACE OF SAID PARTICLLES; B. CONTINUOUSLY FOAMING SAID PARTICLES DURING SAID MIXING TO A VOKUME OF AT LEAST 50% OF THEIR FINAL FORMED VOLUME; C. FORMING AND RESTRAINING SAID FOAMING PARTICLES AND LIQUID BINDER THEREBY CAUSING SAID FOAMING PARTICLES TO SECURELY BONDED INTO A MATRIX OF SAID BINDER; AND D. COOLING SAID RESTRAINED PARTICLES AND LIQUID BINDER TO A TEMPERATURE AT WHICH SAID PARTICLES WILL NOT CONTINUE TO FOAM AND AT WHICH SAID LIQUID BINDER IS TRANSFORMED INTO ESSENTIALLY SOLID BINDER.

    摘要： A method and apparatus for efficiently laying geotextile or like material on a preferably prepared target surface. The apparatus includes a tractor or like machine mountable dispensing device mounted to a tractor or like construction machine and having at least one roll of geotextile or like material rollingly and dispensingly mounted to the device. The apparatus is used in rolling out and laying down geotextile or like material on a target surface as the tractor or like machine drives/rolls/moves along or in near proximity to the target surface.

    摘要： A texturing machine is provided for the subsequent treatment of a freshly produced concrete layer having a width between left and right edges and extending longitudinally in a working direction. Left and right height sensors are arranged to detect a height above the freshly produced concrete adjacent the left and right edges of the layer. At least one crown height sensor is arranged to detect a height above a crown of the freshly produced concrete layer. A controller is configured to receive input signals from the height sensors and to communicate height control sensors to the height adjustable columns and to communicate a crown control system to the crown actuator. A direction sensor may also detect at least one of the edges of the freshly produced concrete layer. The controller may receive a direction input signal from the direction sensor, and the controller may communicate a direction control signal to a steering actuator of one of the ground engaging units of the machine.
