摘要： In some implementations, a controller may cause a gearbox coupled to a rotor to shift between a first gear ratio and a second gear ratio one or more times. The controller may obtain a first set of position data that identifies respective first positions of a gear selector of the gearbox for each shift to the first gear ratio, and a second set of position data that identifies respective second positions of the gear selector of the gearbox for each shift to the second gear ratio. The controller may determine a first calibrated position of the gear selector for a shift to the first gear ratio based on the first set of position data and a second calibrated position of the gear selector for a shift to the second gear ratio based on the second set of position data.

摘要： A system for processing a pavement reinstatement includes a weighing apparatus (502) for measuring a mass of reinstatement material. A reinstatement apparatus (10) is adapted to receive reinstatement dimension information and reinstatement material information and adapted to determine a required reinstatement material mass, and to provide a target air voids content of the reinstatement. The reinstatement apparatus is optionally adapted to receive an indication of the mass measured by the weighing apparatus and the indication is a verification of the weighing apparatus having measured the required mass.

摘要： Provided are a textile-reinforced concrete road paving apparatus and a method of repairing concrete road pavement using the same. The textile-reinforced concrete road paving apparatus can minimize use of construction equipment by using the textile-reinforced concrete road paving apparatus integrally formed to consecutively cut concrete, dispose a reinforcement material, and construct a repaired cross section so as to reduce a construction period, thereby remarkably reducing construction costs. Further, a textile grid reinforcement material, which is a noncorroding reinforcement material, is applied to form the repaired cross section of the concrete road pavement so as to prevent concrete from being detached due to corrosion. Further, a textile reinforced grid is precisely disposed at a required position, and thus the thicknesses of the primary and secondary concrete pavement are precisely adjusted, and thus construction precision can be increased.
