Utility Adjustments for Asphalt Paving in Arizona
As manhole and valve adjustment contractors serving Phoenix, Scottsdale, Mesa, and municipalities statewide, we raise manholes to grade, reset water valves, and adjust gas and electrical vaults flush with the finished asphalt, coordinated with utility owners so every casting is inspected, accepted, and backed by a 2-year workmanship warranty.
FLUSH TO GRADE, TIGHT TO PAVEMENT
Anyone asking who adjusts manholes before an asphalt overlay needs a contractor who treats utility riser adjustment paving as its own trade, not an afterthought. American Asphalt specializes in manhole, sewer, water valve, and vault adjustments across Phoenix, Chandler, Gilbert, and communities statewide, keeping underground infrastructure accessible while setting every casting flush with the finished overlay or new pavement that establishes final grade.
With more than 30 years of experience as a family-owned, in-house Arizona paving contractor, our crews raise, lower, and reset castings to grade, drainage, and ADA path-of-travel standards on roadways, parking lots, and commercial developments, coordinated with the utility owner and released only after a final rim check and inspection.

PAVEMENT LIVES AT THE CASTING
Every parking lot and roadway fails first at the utilities. Proper adjustments, the right frame, the right collar, the right compaction, turn the weakest point in the pavement into its most durable one, and keep water out from underneath.
Eliminates trip hazards & pothole starters
A high or low utility casting is the #1 pothole starter in a parking lot. Flush, sealed adjustments remove trip hazards and stop water from getting under the pavement.
Protects underground infrastructure
Proper riser rings, HMA collars, and load-rated frames keep vehicle loads off the utility itself, protecting valves, vaults, and manhole cones from cracking or shifting.
Restores drainage & prevents ponding
Catch basins, area drains, and storm inlets set to correct rim elevation and cross-slope get water off the lot instead of pooling at the low structure.
Meets city, DOT & ADA criteria
Rim tolerances, cover load ratings, and adjacent slopes placed to MAG, ADOT, and ADA path-of-travel criteria, cleared for municipal and public-agency final acceptance.
Extends pavement life around castings
The pavement around a utility is where new lots fail first. Correct collars, tack, and compaction stop the ring cracking that fails cheap raise-and-pave work.
Coordinated with the utility owner
Whether the project is a municipal roadway in Chandler or a commercial lot in Avondale, we coordinate locates, shutdowns, and access with water, sewer, gas, electric, and telecom owners so adjustments are approved, inspected, and released.

LOCATE, SET, COLLAR
Every American Asphalt utility adjustment, whether on a Phoenix municipal street or a Queen Creek commercial lot, follows the same disciplined sequence: locates first, precision leveling to final grade, and a proper HMA collar around every casting so the pavement stays tight for years, not months.
