Potholes (deep patch) Sample Clauses
The 'Potholes (deep patch)' clause defines the responsibilities and procedures for repairing significant potholes in a roadway using a deep patch method. This typically involves removing the damaged pavement, preparing the underlying base, and installing new material to restore the road's structural integrity. The clause ensures that repairs address not just surface damage but also underlying issues, thereby providing a durable solution and minimizing the risk of recurring potholes.
Potholes (deep patch). Surface course and base course materials shall be excavated to a depth necessary to reach firm, suitable material. The minimum depth of excavation shall be two inches and the maximum depth of excavation shall be to the top of the Subgrade. The edges of the prepared hole shall be extended to form a vertical face in unfractured asphalt surfacing. The prepared hole shall generally be circular or rectangular in shape, dry, and cleaned of all loose material. Prepared potholes shall be patched or barricaded immediately. The faces of the prepared hole shall be tacked with a slow-setting emulsified asphalt. The bituminous mixture shall be placed in layers not exceeding a compacted depth of two inches. Each layer shall be compacted thoroughly with hand or mechanical tampers or rollers. Compaction shall not be done with equipment wheels. Upon completion, the compacted patch in the pothole shall be flush, with a tolerance or approximately one-fourth inch to one-half inch above the level of the adjacent pavement.
Potholes (deep patch). Remove the surface course and base course as deep as necessary to reach firm support; extend horizontally at least six (6) inches into good asphalt surfacing surrounding the cracked area. Make the cut square or rectangular with faces straight and vertical. Prime the bottom and faces using MC70, MC250, MC800, or emulsified asphalt (penetration type). Backfill the hole with asphalt mix and compact. Use 2-inch layers if the hole is more than four (4) inches deep. Compact each layer thoroughly with mechanical tampers or rollers. Compaction shall not be done with equipment wheels without prior approval. The patch when completed and compacted shall be flush with surrounding surface.
