A work machine for removing asphalt from a roadway is disclosed. The work machine includes a plurality of blade members to remove asphalt from the roadway. The plurality of blade members are interconnected by way of hinges.

A modification of a cold milling machine used to remove concrete and asphalt from an existing highway is disclosed, including a milling drum segmented into two or more sections with the drive train for the milling drums passing through the core of the milling drum and supported via a journal or bearing to the outside of the machine. One or more sections of a milling drum may be added to the drum to vary its length. The sections of the milling drum can be added by bolting segments of the drum ont...

A concrete breaking apparatus includes a non-circular multi-lobed impact roller connected via an axle to a wheeled frame such that the roller rolls upon the ground as the frame is towed by a tractor. Each lobe of the roller includes a ridge extending across the width of the roller and projecting outwardly from the impact surface of each lobe along a line parallel to the axle and generally centrally located within the dynamic impact region of the impact surface. The ridge may take various configu...

A ground working device is formed from a sub-frame having a first side and a second side, plural discs mounted for rotation on the sub-frame between the first side and the second side about an axis that extends from the first side to the second side; and a set of scoops mounted on each disc in ground contacting position. The scoops efficiently lift the ground surface material, which falls to the ground in a sorted manner with coarser material on top. A motor is operatively connected to the plura...

A bi-directional surface leveling system comprises a chassis attachable to a motion source and having a hitch, a grader frame pivotably connected to the hitch and supporting a box grader, and a forward frame pivotably attached to the grader frame and having a caster wheel for supporting the chassis. The box grader holds a bi-directional earth grading tool. Also included is a damping assembly attached to the hitch to dampen upward movement of the grader frame. A powered assembly is pivotably conn...

A multi-sided wheel to replace one of the wheels of an existing cold milling machine. The wheel has a series of flat surfaces in spaced relationship. The flat surfaces allow the machine to drop its cutting drum relative to the surface over which the machine is traveling to cut a rumble strip. As the wheel rotates, it will support the machine on one of the points formed by the confluence of two adjacent flat surfaces, thereby raising the machine and causing it to raise its cutting drum out of the...

An apparatus is disclosed for the cold, in-place recycling of asphalt paving of an asphalt roadway. The apparatus is self-propelled, and it includes a cylindrical milling drum mounted at a medial location along its longitudinal length and which serves to remove a thickness of the asphalt paving and break the same into particles as the apparatus moves forwardly along the roadway. The particles are lifted to a separating screen which is positioned forwardly of the drum, and the particles are there...

In a method and apparatus for resurfacing a road, the road surface is first plastified and broken-up by first and second separable devices. The broken-up material is immediately distributed on the road surface by the second device, whereby the broken-up material is simultaneously rearranged and profiled or contoured without the introduction of fresh asphalt or bituminous material at this point of time. A road surfacing or repaver apparatus forming a third separate device then introduces fresh as...

A method and apparatus for resurfacing an existing paved roadway to produce a new roadway surface having a predetermined grade and cross slope, particularly wherein the existing paved roadway has at least one irregular depression therein extending below the predetermined grade and wherein the portion of the roadway above the predetermined grade is removed in particulate form for use as a recyclable aggregate in resurfacing the roadway.

Disclosed is an automotive milling machine for machining ground surfaces, comprising an engine frame (2), a movable milling drum (8) which is mounted on the engine frame (2), at least one conveying device (14,18) which is arranged on the engine frame (2) and takes over the milled material (3) from the milling drum (8) at a transfer location (5), and a device (20) sucking off the air that is polluted with dust and fumes. The milled material (3) is enclosed by a duct (16,16a,16b) on the at least o...
