Abstract
Abstract 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.

Claim 1
Independent Claim
139 words
A method for resurfacing an existing paved roadway to produce a new roadway surface having a predetermined grade and cross slope, wherein the existing paved roadway has at least one irregular depression therein extending below the predetermined grade, the method comprising the stpes of: removing the material of the paved roadway within a predetermined distance of the depression to a predetermined depth below the bottom of the depression; applying a substantially uniform layer of new pavement material within the depression, the layer having an upper surface above the predetermined grade and a density substantially the same as the density of the existing pavement material surrounding the depression; and, passing a rotating planing cutter over the paved roadway at the predetermined grade and cross slope to remove the material of the paved roadway above the predetermined grade and cross slope.

Claim 3
Independent Claim
114 words
A method for resurfacing an existing paved roadway of the asphalt type to produce a new roadway surface, the method comprising the steps of: passing a rotating planing cutter over the paved roadway to cut the top portion of the paved roadway to a predetermined grade and cross slope in a full offset pattern having laterally adjacent cutting paths longitudinally offset on the order of one full length of each path; and, passing a fixed moldboard over the paved roadway at the predetermined cross slope and at a second predetermined grade slightly above the predetermined grade to remove the material of the paved roadway above the second predetermindd grade and the predetermined cross slope.
