AI Technical Summary

Benefits of technology

This invention is about an attachment for a distributor vehicle that applies asphalt to parking lots and paving surfaces. It consists of a truss and a broom head with bristles. The attachment can be raised and lowered to control the application of asphalt. The distributor vehicle has a reservoir for storing asphalt and a pneumatic system to deliver the asphalt to the applicator. The method involves lowering the attachment onto the surface and emitting the asphalt onto it using the applicator. The broom head then spreads the asphalt against the surface. This invention allows for easier and more efficient application of asphalt to surfaces.

Problems solved by technology

However, this process requires passing over a surface at least twice, which increases time that a road or other surface is out of commission and increases labor costs.
It also often leaves the surface looking like a gravel road with dust issues and loose aggregate that can break windshields.
However, the trailer following the distributor vehicle includes its own wheels, which roll through and can damage the asphalt while also accumulating the asphalt, thereby hindering the trailer's operation.
Additionally, such previously-used trailers must be large and heavy enough to press the asphalt onto the surface, which makes the trailer unwieldy, especially when the distributor vehicle needs to reverse.
The trailer is also prone to sliding off an edge of a surface, such as when negotiating a curve or slope.

Abstract

An attachment apparatus for a distributor vehicle configured to apply asphalt onto a surface is provided. The attachment apparatus comprises a truss and a broom head attached to the truss. The broom head comprises a plurality of bristles. The attachment apparatus further comprises a drive assembly configured to shift the truss and the broom head between a raised position and a lowered position with respect to the surface.

Description

RELATED APPLICATION[0001]The present non-provisional patent application claims priority to U.S. Provisional Patent Application Ser. No. 62 / 967,413, filed on Jan. 29, 2020, and entitled “ASPHALT APPLICATION SYSTEMS AND METHODS,” with the entirety of the above-identified provisional patent application being hereby incorporated by reference into the present non-provisional patent application.FIELD OF THE INVENTION[0002]The present invention generally relates to asphalt distributor vehicles, distributor vehicle attachments, and methods of applying asphalt to a pavement surface.BACKGROUND[0003]Distributor vehicles can be used to apply asphalt (e.g., hot liquid asphalt cement or asphalt emulsion) to pavement surfaces, such as roads, parking lots, etc. The distributor vehicles often use a two-step, chip seal process to apply liquid asphalt and then an aggregate on top of the asphalt. Generally, the distributor vehicle will distribute asphalt onto the surface, and a separate vehicle will fo...
