A road striping removal and particulate capturing combination system includes a chassis having a front end and a rear end. A plurality of wheels is rotatably coupled to the chassis and extends downwardly therefrom. The chassis includes an open bottomed housing having an upper wall and a perimeter wall that is attached to and extends downwardly from the upper wall. A particulate conduit extends through the upper wall. A particulate nozzle is fluidly coupled to the particulate conduit. The particulate conduit delivers particulate under pressure to the nozzle such that the particulate is ejected from the nozzle toward road striping as the striping passes under the upper wall. A vacuum conduit is fluidly coupled to an interior space bounded by the housing. The vacuum conduit is fluidly coupled to a vacuum to suction the particulate after the particulate has struck the road surface.

The present invention relates to a method for controlling a road milling machine comprising a milling drum and a rear blade when there is an obstacle located in the ground to be milled, comprising the following steps: a) Milling the ground at a predetermined milling depth (FT) along a working direction (a); b) Advancing the road milling machine in the working direction (a) towards the obstacle located in the ground; c) Raising the milling drum and the rear blade out of the ground in the working direction (a) in front of the obstacle; d) Moving over the obstacle in such a way that the milling drum remains out of contact with the obstacle; e) Lowering the milling drum and the rear blade to the predetermined milling depth (FT) in the working direction (a) behind the obstacle and continuing the milling of the ground, wherein the road milling machine is controlled in such a way that in step c) the raising of the milling drum is carried out before the raising of the rear blade out of the ground, wherein the road milling machine continues to move in the working direction (a) between the raising of the milling drum and the raising of the rear blade. The present invention also relates to a road milling machine for performing the method.

A chipping robot has a chipping gun attached to the end of a multi-axis robotic manipulator mounted on a powered, movable, platform that can be raised and lowered to access the underside of structures that may be substantial distances above the ground, for example, the underside of an elevated highway. The entire assembly is maneuverable under the work area and the platform may raised to access the concrete. Once the work area is in reach of the arm, the device is able to use numerous tools to complete essential steps of chipping portions of the concrete.

Methods, compositions and systems for prolonging the lives of transportation surfaces, including pavement, runways, bridges and parking structures include physically altering the transportation surface and chemically protecting the transportation surfaces. Physical alteration of a transportation surface may include physically altering one or both of a microtexture and a macrotexture of the transportation surface. Chemical protection of a transportation surface may include hardening and/or densifying the transportation surface. The transportation surface may be chemically protected while physically altering the transportation surface or after the transportation surface has been physically altered.

A milling machine includes a frame, a rotor coupled to the frame and vertically adjustable, a chamber coupled to the frame and at least partially surrounding the rotor, a speed sensor configured to measure a speed of the machine, a height sensor configured to measure a height of the rotor, a ground characteristic sensor configured to measure a ground characteristic, and a controller. The controller is configured to receive the speed of the machine from the speed sensor, receive the height of the rotor from the height sensor, receive the ground characteristic from the ground characteristic sensor, determine a target speed for the machine, determine a target height for the rotor, adjust the speed of the machine to the target speed, and adjust the height of the rotor to the target height.
