Asphalt Paving in West Mifflin, PA

Asphalt paving in West Mifflin has to account for what is under the pavement. Wikipedia describes the borough as largely hilly and wooded, but also notes that coal mining affected its small streams, that steel mill byproducts such as slag and fly ash were dumped in parts of the borough, and that developers filled ravines and small parcels to create level ground. Fill can settle unevenly for years. A driveway or lot built over it may develop dips and cracks that have nothing to do with the asphalt itself. We check for soft or settling ground before we quote, and we build the base to suit it.

A borough built in the 1950s and 1960s

West Mifflin became a borough on December 11, 1942. It had 17,985 people in 1950, 27,289 in 1960 and 28,070 in 1970, then 19,589 in 2020. The 2020 census counted 9,407 housing units, so a large share of homes and driveways date from the postwar boom. Those driveways are now sixty years old or more, and many need replacement rather than another patch.

Driveway replacement and repair

On residential jobs here we most often:

• Replace driveways that have alligator cracking and soft spots across the surface
• Rebuild sunken aprons at the street
• Dig out and rebase areas over fill that keep settling
• Resurface sound driveways with a new overlay
• Crack seal and sealcoat newer pavement

When a driveway sits on fill that is still moving, we explain that up front. A stronger base and geotextile fabric can help bridge minor settlement, but no paving job can stop the ground below from moving entirely.

Busy employers and their lots

West Mifflin is home to Kennywood Park, Allegheny County Airport, the Bettis Atomic Power Laboratory, US Steel's Mon Valley Works Irvin Plant and the Community College of Allegheny County's South Campus. Most of the borough lies in the airport's Class D airspace. Along with those big sites are many smaller businesses, churches and shops whose lots need regular patching, sealcoating and striping. We phase that work so customers can still get in.

Route 885 and the state roads

Wikipedia notes that PA 885 is the main road through most of the borough, meeting PA 51 nearby in Whitehall, and that no interstate passes through. Where a lot or driveway entrance meets a state route like 885, changes in PennDOT right-of-way need a Highway Occupancy Permit, according to PennDOT's minimum-use driveway fact sheet. We check before working at the entrance.

On the Monongahela

The borough's eastern boundary touches the Monongahela River in three places, and the hillsides above it are steep. Homes on those slopes need driveways built for runoff, with the water directed off the pavement before it gathers at the garage. Call (412) 796-9361 for a free estimate in West Mifflin.
