Abstract
A method for repairing an opening formed in and below a section of pavement, comprising the steps of partially filling the opening with an unshrinkable filler material such that an upper surface of the filler material is near a lower surface of the section of pavement, heating an upper portion of the filler material so that the upper portion is substantially dried and becomes set, and substantially immediately thereafter making a permanent patch in the pavement section above the dried filler material.
