Definitions

  • the invention relates to a road construction machine and a method for repairing road surfaces, with which damaged spots on roads, e.g. Cracks and the like, covered with a non-woven material and sealed against the damaging effects of moisture and frost.
  • the invention has for its object to provide a road construction machine and a method of the type specified, which allow a detachment of complex manual work with structurally simple means and with which the quality and weather-resistant reliability of the repair site can be increased.
  • the road construction machine which is formed in the front area of the chassis frame with the advantageously automatically controllable links of a fleece laying unit, a uniform laying process for a wide variety of damaged areas can be achieved.
  • a precisely coordinated application of the adhesive and the nonwoven layer covering it a homogeneous, interference-free connection zone is achieved, the amount of adhesive, the thickness of the nonwoven and the contact pressure imparted by the pressure member enabling an optimal setting process when the adhesive is solidified, so that a constant repair of the pavement has been achieved even in harsh environmental conditions.
  • the continuous feeding of the transport roller and cutting the fleece to length by means of the cutting member without interrupting the unwinding process enables the laying sections to be processed almost indefinitely, with the laying speed being controlled by the automatic control of the individual members of the fleece laying unit to the vehicle speed of the machine as a whole can be coordinated.

  • this is designed as a fleece laying unit, the laying members, generally designated 13, are arranged in the front region of the chassis 8. With these controllable individual members, a nonwoven material located on a nonwoven supply roll 14 can be fed via a feed member 16 into the region of the roadway section 10 having the crack 11.
  • An adhesive 19 supplied from an adhesive tank 18, in particular in the form of a bitumen mixture, is applied to this prepared roadway area via a ramp syringe 17 which enables an adhesive to be discharged, and then at least one fleece section 20 is placed on the machine 1 in the direction of the arrow 21 while the machine 1 is continuously moving, and a wrinkle-free contact is made possible by means of one Pressure member 22 is placed in an intended position on the road surface 9 or the crack 11.
  • the adhesive 19 can be applied with appropriate control of the laying members 13 so that the adhesive and adhesive properties then both an optimal setting in the area of the crack 11 and, for example, the degree of saturation of the fleece material Allow the respective fleece section 20 coordinated setting time.
  • the respective setting times of the applied adhesive 19, the fleece section 20 fed to it and the pressing in a subsequent pressing phase with the pressing member 22 can be determined via the respective installation positions of the individual members, e.g. are determined by a distance A of the ramp syringe 17 to the installation area or a distance B of the pressure member 22 to the installation area. It is also conceivable to control the individual laying members 13 by means of a computer (not shown), which can be provided in a cab 23 located on the chassis 8 and forming a control area, in such a way that the driving speed is detected in the direction of the arrow 21 and as a function thereof the ramp syringe 17 is positioned in an arrow direction 24 and / or the pressure member 22 is moved in accordance with an arrow direction 25.
