Machine, system and method for road construction

A road building machine, comprising:

• a vehicle;
• a distribution arrangement mounted at a trailing end of the vehicle and configured to spray an asphalt material through a plurality of nozzles onto a surface as the vehicle moves over the surface;
• a plurality of sensors mounted across a leading end of the vehicle and configured to generate signals indicative of textures of the surface during movement of the vehicle over the surface, wherein a number of the plurality of sensors is equal to a number of independently controllable groups of the plurality of nozzles;
• a locating device mounted to the vehicle and configured to detect locations of the textures;
• and
• a controller in communication with the distribution arrangement, the plurality of sensors, and the locating device, the controller being specially programmed to:
• determine amounts of the material to be applied to the locations of the textures based on the signals;
• and
• automatically cause the distribution arrangement to distribute the amounts of the material onto the surface at the locations of the textures as the vehicle moves over the surface.

A distribution arrangement for a road building machine, comprising:

• a vessel mountable to the road building machine and configured to hold an asphalt material;
• a spray bar configured to extend across a trailing end of the road building machine;
• a pump configured to press the asphalt material from the vessel through the spray bar;
• a plurality of nozzles in fluid communication with the spray bar and configured to spray the asphalt material onto a surface as the road building machine moves over the surface;
• a plurality of valves configured to regulate flows of the asphalt material through the plurality of nozzles;
• a plurality of sensors configured to mount across a leading end of the road building machine and to generate signals indicative of textures of the surface during movement of the road building machine over the surface, wherein a number of the plurality of sensors is equal to a number of independently controllable groups of the plurality of nozzles;
• a locating device configured to mount to the road building machine and to detect locations of the textures;
• and
• a controller in communication with the plurality of valves, the plurality of sensors, and the locating device, the controller being specially programmed to:
• determine amounts of the asphalt material to be applied to the locations of the textures based on the signals;
• and
• automatically cause the plurality of valves to pass the amounts of the asphalt material through the plurality of valves and on to the surface at the locations of the textures as the road building machine moves over the surface.
