Specifications include, but are not limited to: Materials and Equipment. The following material shall be available to complete this work: - Patch Material - DelDOT approved High Performance Cold Patch material shall be used. The following equipment shall be available to complete this work: - Sponge or other absorbent material - Used to extract water from the hole. - Compaction Hammer - mechanical (electrical, pneumatic, or gasoline driven) tamping device with a flat, circular tamping face smaller than 6 inches in diameter. Construction Method. After core removal from the hole, remove all excess water from within the hole, and prevent water from re-entering the hole. Place the patch material in lifts no greater than 3 inches and compact with mechanical tamping device. If the hole is deeper than 3 inches, use two lifts of approximately equal depths so that optimum compaction is achieved. Make sure that the patch surface matches the grade of the existing roadway. Make every effort to achieve the greatest possible compaction. Performance Requirements. The Engineer will judge the patch on the following basis: - The patch shall be well compacted - The patch surface shall match the grade of the surrounding roadway surface.
