Abstract
An apparatus for crushing fragments of asphalt removed from a roadway by a paved roadway planing apparatus includes a grid upon which the fragments are deposited and a crushing tool having a plurality of cutting bits mounted on a rotating drum for movement along circular paths intersecting the grid. The crushing apparatus can be towed behind the paved roadway planing apparatus to receive the asphalt removed from the roadway from the paved roadway planing apparatus and to redeposit the crushed fragments on the roadway.
Claims10
In combination with a roadway planer producing fragments of asphalt from a paved roadway and discharging the fragments from the rear end thereof a distance above the roadway:
- a chassis connected to the rear end of the roadway planer;
- wheel means supporting the chassis rearwardly of the planer;
- and
- crushing means carried by the chassis for receiving the fragments of asphalt from the roadway planer and reducing the size of the fragments exceeding a predetermined dimension, comprising:
- a grid comprising a plurality of substantially parallel, spaced apart bars positioned to receive the fragments of asphalt thereon, the distance between the bars being substantially equal to said predetermined dimension;
- a plurality of cutting bits sized to move between the bars;
- and
- means for repetitively moving the cutting bits between the bars for reducing the size of the fragments exceeding said predetermined dimension.
In combination with a roadway planer producing fragments of asphalt from a paved roadway and discharging the fragments from the rear end thereof a distance above the roadway:
- a chassis connected to the rear end of the roadway planer, wherein the chassis is connected to the roadway planer by at least two transversely spaced lugs to remain transversely parallel with the roadway planer;
- wheel means supporting the chassis rearwardly of the planer, wherein the wheel means includes a walking beam pivotally connected to the chassis for pivotation with respect to the chassis about a horizontal axis extending in the directional movement of the roadway planer, and a wheel connected to each end of the walking beam;
- and
- crushing means carried by the chassis for receiving the fragments of asphalt from the roadway planer and reducing the size of the fragments exceeding a predetermined dimension.
