Keystone Turlock Asphalt Paving is an asphalt paving contractor serving Merced, CA, handling commercial paving, driveway installation, pothole repair, and parking lot maintenance for homes and businesses throughout the city. We have operated in the Central Valley since 2017 and respond to every estimate request within one business day.

Merced's active commercial corridors along Highway 99 and its major arterials see heavy delivery and customer traffic that breaks down parking lots and access drives faster than light residential use. Our commercial asphalt paving services are designed for these high-demand sites, with base prep and mix specs matched to the load and traffic volume.
Many Merced homes near downtown and on the west side were built in the 1950s through 1970s, and their original driveways have been through decades of clay soil movement. A properly graded new driveway with a compacted aggregate base is the most durable solution for properties on Merced's valley-floor soils.
Merced's wet winters and expansive clay soils are the main drivers of pothole formation - moisture weakens the sub-base, and the surface collapses under vehicle loads. Quick, properly bonded repairs stop the damage from spreading and protect surrounding pavement.
Merced driveways and parking lots develop surface cracks from the seasonal shrink-swell of clay soils underneath. Sealing those cracks while they are still narrow - before water enters and weakens the base - extends pavement life by several years at a fraction of the cost of resurfacing.
When a Merced parking lot or driveway shows widespread surface wear but the base beneath is still structurally sound, a resurfacing overlay restores the surface without a full tearout. It is the most cost-effective path forward for surfaces that have reached the end of their top layer's life.
Merced commercial property owners near UC Merced and along the Highway 99 frontage need maintenance programs that keep parking surfaces functional and compliant with ADA striping requirements. A scheduled approach to sealcoating, crack sealing, and restriping reduces long-term paving costs significantly.
Merced sits on the flat floor of the San Joaquin Valley, where the soils are heavily clay-based and behave differently from one season to the next. Winter rains saturate those clay soils and cause them to swell, putting upward pressure on driveways and parking lot slabs. As the long dry summer sets in, the ground contracts and pulls away from the edges of paved surfaces, leaving gaps that allow water to infiltrate next winter. This cycle repeats every year and is the primary reason why asphalt in Merced without a properly compacted aggregate base fails noticeably faster than properly installed work.
The city's mix of older homes and active commercial corridors creates demand across the full range of paving services. Residential neighborhoods near downtown and on the older west side have driveways from the 1950s through 1970s that are well past their original service life. Newer subdivisions on the north and east sides - many built in the 2000s near UC Merced - are now reaching the age where they need their first major maintenance cycles. Commercial properties along Highway 99 and arterials like R Street and Martin Luther King Jr. Way carry the volume and vehicle weight that make regular parking lot maintenance a financial necessity rather than an optional upgrade.
Our crew works throughout Merced regularly, and we understand the local conditions that affect asphalt paving work here. Projects that involve work within a public right-of-way or that add new impervious surface often require coordination with the City of Merced Building Division, and we walk our customers through that process so there are no surprises. The flat terrain makes equipment access straightforward in most parts of the city, but the clay soil conditions require specific base prep that we factor into every job from the start.
Merced is well connected by State Route 99 running north-south and State Route 140 heading east toward Yosemite, which means we can move crews and equipment in and out of the city efficiently from our base. From the older streets near Applegate Park to the newer growth areas near UC Merced on the northeast side, we have worked across the full range of Merced neighborhoods and property types. We also serve Atwater, CA to the north, where the same valley conditions apply, and our home base in Turlock, CA means we are never more than a short drive from any job in Merced.

We schedule to fit your calendar and handle all surface preparation before laying any material - including cleaning, crack routing, edge cutting, or base regrading as needed. Prep determines how long the result lasts.
We walk the finished work with you before we leave and give you clear curing guidelines so you know exactly when the surface is ready for foot and vehicle traffic.

(209) 638-0235Merced is the county seat of Merced County and one of the mid-sized cities in California's San Joaquin Valley, with a population in the range of 85,000 to 90,000 residents. The city is known throughout California as the "Gateway to Yosemite" because State Route 140 runs east from Merced directly toward Yosemite National Park, making it the last major city before the park entrance. Merced's older neighborhoods near downtown and on the west side have modest single-family homes built from the 1940s through the 1970s, many with concrete or aging asphalt driveways that reflect decades of seasonal soil movement. You can learn more about the city's history and structure through the Merced, California Wikipedia article.
The opening of UC Merced in 2005 on the northeast side of the city brought significant growth to that part of town, with new apartment complexes, student housing, and supporting commercial development spreading outward from the campus. This newer development represents a different generation of paving needs - surfaces built in the mid-2000s are now reaching the age where initial sealcoating and maintenance cycles are due. Applegate Park in the central part of the city is a well-known local gathering spot and free zoo. We also serve communities nearby, including Livingston, CA to the north, which shares the same flat valley terrain and clay soil conditions as Merced.
