Abstract: A method for operating a working machine including a fluid storage tank on a roadway includes providing a spray assembly that is in fluid communication with the fluid storage tank. The spray assembly further includes a plurality of nozzle assemblies, each of which comprises a direct acting valve having a solenoid switch assembly and a valve assembly. The spray assembly also includes a controller that is operatively connected to each of the direct acting valves for controlling the opening and closing thereof. The controller includes a power source, a spray control, an input module and an output module. The input module is operatively connected to the solenoid switch assembly of each nozzle assembly and to the spray control, and it is adapted to determine if the valve assembly of each nozzle assembly is open or closed. The output module is operatively connected to the spray assembly and to the power source, and it is adapted to energize the solenoid switch assembly of each nozzle assembly in the spray assembly. A selector is operatively connected to the controller and may be employed by an operator of the working machine to selectively operate one or more of the direct acting valves in order to provide a desired spray pattern of fluid from the fluid storage tank onto the roadway.

Abstract: A screed assembly for an asphalt paving machine includes a lower screed plate, an upper screed plate and a heating element that is in contact with the lower screed plate. The screed assembly also includes a compression bolt assembly having a primary bolt, a compression bolt and a compression spring. The primary bolt has a through hole, and the compression bolt is adapted to be inserted through the hole of the primary bolt. The compression spring is adapted to be placed over the lower end of the primary bolt, so that the compression bolt assembly may cooperate with the upper screed plate to apply a compression force to the heating element on the lower screed plate.

Abstract: A working machine such as a road milling machine of an asphalt paving machine has an automatic grade and slope control system that causes the machine to maintain a pre-selected grade and slope with respect to a reference without significant operator input. A calibration system employs a calibration controller to calibrate the automatic grade and slope control system. The calibration controller causes a current to be sent to a valve that operates a linear actuator that may be employed to change the attitude of the frame of the working machine. The calibration controller uses feedback from at least one sensor, such as a height-measuring sensor or a slope-measuring sensor, in an iterative process that determines the minimum current necessary to cause a change in the attitude of the frame of the working machine. Once this minimum value is determined, the system will establish the optimum settings for the automatic grade and slope control system to improve its efficiency and cause it to operate more smoothly.
Abstract translation: 沥青摊铺机的道路铣床等工作机械具有自动等级和坡度控制系统，使得机器相对于参考线保持预先选定的档次和坡度，而不需要大量的操作员输入。 校准系统采用校准控制器校准自动坡度和坡度控制系统。 校准控制器使得电流被发送到操作线性致动器的阀，该线性致动器可用于改变工作机器的框架的姿态。 校准控制器在迭代过程中使用来自至少一个传感器（例如高度测量传感器或倾斜测量传感器）的反馈，该迭代过程确定导致作业机器的框架姿态变化所需的最小电流。 一旦确定此最小值，系统将建立自动坡度和坡度控制系统的最佳设置，以提高其效率并使其运行更加平稳。

Abstract: A working machine for use in milling the surface of a road includes a drive engine that produces engine exhaust gases. The working machine also includes a milling drum that is mounted for rotation against the surface of the road so as to generate milled material including dust from the road surface. The milling drum is contained within a milling chamber, and a spray assembly directs water into the milling chamber in such a manner that, during a period of rotation of the milling drum against the surface of the road, at least a portion of the water is converted to a vapor. A conduit is provided for conducting at least a portion of the engine exhaust gases into an enclosed space in communication with the milling chamber to raise the temperature of a gas stream therein containing vapor and dust from the milled material.

Abstract: A method and system for guiding a road construction machine using a machine guidance system comprising at least one each of a machine position sensor, a laser-based sensor, and a processing unit. The machine position sensor first measures a position of a road construction machine relative to a road boundary condition. The laser-based sensor then captures a series of scans corresponding to the boundary condition. The processing unit, using the scans, determines an ideal path of travel for the road construction machine. Based on the ideal travel path, the machine guidance system provides instructions to align the current travel path of the road construction machine to the ideal travel path.
