Problems solved by technology

Depending upon usage density, base conditions, temperature variation, moisture variation, and / or physical age, the asphalt surface eventually becomes misshapen, non-planar, unable to support wheel loads, or otherwise unsuitable for vehicular traffic.
Although the asphalt processor of the '207 patent may sufficiently remove spent asphalt from a roadway surface, it may be inefficient.
In particular, because the asphalt processor of the '207 patent does not have any way to store the fractured asphalt, the transport work machine must be present any time the roadway surface is being removed.
The constant accompaniment of the transport work machine and delays associated with moving a laden transport work machine away from the asphalt processor and moving an empty transport work machine into place may decrease the efficiency of the rehabilitation process.
In addition, the deposit location of the fractured asphalt associated with the processor of the '207 patent could result in further inefficiencies.
Too great of a speed differential between the transport work machine and the processor could result in fractured asphalt being unintentionally deposited on the roadway or the transport work machine and processor colliding.
Constant regulation of this speed differential may be time consuming and difficult.

Embodiment Construction

[0014] For the purpose of this disclosure, the term “asphalt” may be defined as a mixture of aggregate and asphalt cement. Asphalt cement may be a brownish-black solid or semi-solid mixture of bitumens obtained as a byproduct of petroleum distillation. The asphalt cement may be heated and mixed with the aggregate for use in paving roadway surfaces, where the mixture hardens upon cooling.

[0015]FIG. 1 illustrates an exemplary work machine 10 having multiple systems that cooperate with a tow machine 12 and a transport vehicle 14 to “peel” or remove spent asphalt from a roadway surface. In particular, work machine 10 may embody an asphalt peeler having a removal system 16, a grinding system 18, a storage system 20, and an off-loading system 22. It is contemplated that additional components and systems may be included within work machine 10 such as, for example, an auxiliary power system (not shown).

Abstract

A work machine for removing asphalt from a roadway is disclosed. The work machine includes a removal device configured to remove asphalt from a roadway. The work machine also includes a storage bin operatively connected to the removal device and configured to house the removed asphalt.

Description

RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Patent Application No. 60 / 604,982, entitled “Advancements in paving technology,” which was filed on Aug. 27, 2004, the disclosure of which is expressly incorporated herein by reference.TECHNICAL FIELD [0002] The present disclosure relates generally to an asphalt-removing work machine and, more particularly, to an asphalt-removing work machine having a storage bin. BACKGROUND [0003] Many miles of asphalt-surfaced roadways have been built to facilitate vehicular travel. Depending upon usage density, base conditions, temperature variation, moisture variation, and / or physical age, the asphalt surface eventually becomes misshapen, non-planar, unable to support wheel loads, or otherwise unsuitable for vehicular traffic. [0004] In order to rehabilitate the roadways for continued vehicular use, spent asphalt may be removed in preparation for resurfacing. One device utilized for the removal of spent asphalt i...
