Method for repairing holes in pavement

Abstract

A method for repairing a hole in pavement comprises the steps of filling the hole with a filling material. One or more waterproofing cover sheet are placed over the hole, such that the hole and a portion of a surrounding area of the hole are covered. The waterproofing cover sheet is heated so as to make the waterproofing cover sheet adhere to the pavement, whereby the waterproofing cover sheet generally prevents water from infiltrating into the repaired pavement.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This patent application is a continuation-in-part of U.S. patent application Ser. No. 11 / 076,945, filed on Mar. 11, 2005 by the present applicant.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to the process of repairing holes in pavement, such as potholes in roads, streets and the like. [0004] 2. Background Art [0005] Potholes commonly develop in pavement and are a constant source of inconvenience and danger. They are also notoriously difficult to repair, especially in colder climates. Repeated cycles of freezing and thawing can render pothole repairs ineffectual if water infiltrates into the repaired pavement and expands when temperatures drop below freezing. Consequently, it is desirable to limit the amount of water that can infiltrate into repaired pavement. [0006] Furthermore, vehicular traffic tends to wear out repaired potholes. It is thus desirable to protect a repaired pothole f...

AI Technical Summary

Benefits of technology

[0014] Therefore, in accordance with the present invention, there is provided a method for repairing a hole in pavement, comprising the steps of: i) filling the hole with a filling material; ii) placing at least one waterproofing cover sheet over the hole, such that the hole and a portion of a surrounding area of the hole are covered; and iii) heating the waterproofing cover sheet so as to make the waterproofing cover sheet adhere to the pavement; whereby the waterproofing cover sheet generally prevents water from infiltrating into the repaired pavement.

Problems solved by technology

Potholes commonly develop in pavement and are a constant source of inconvenience and danger.

They are also notoriously difficult to repair, especially in colder climates.

Repeated cycles of freezing and thawing can render pothole repairs ineffectual if water infiltrates into the repaired pavement and expands when temperatures drop below freezing.

Furthermore, vehicular traffic tends to wear out repaired potholes.

This is not practical in colder climates because the coating of tar requires that machinery providing hot tar be available at the pothole location.

The adherence of such a top mat is less than ideal, especially in colder climates.

This is also a method that is ill adapted to the rigors of a cold climate, since it requires the machinery and time necessary to use a cement to repair the hole.
