Asphalt Paving in Victorville, CA

Asphalt paving in Victorville faces about 109 days a year at 90 degrees or hotter and 79 nights a year at or below freezing, according to the city's long-running weather records. July's average high is about 97.5 degrees and January's average low is about 33. That is a swing of more than 60 degrees between the hottest afternoons and the coldest mornings, and asphalt expands, softens, shrinks and stiffens through every one of those cycles. Add steady wind, sand and a dry climate that drains the life out of the binder, and you get pavement that ages faster than it would almost anywhere on the coast.

Heat: softening and drying out

On a summer afternoon, a black driveway gets much hotter than the air. Hot asphalt is soft, so tires, trailer jacks and even patio furniture leave dents in it. Over the years, heat and ultraviolet light also oxidize the binder that holds the stone together. The surface fades to gray, gets brittle and starts shedding small stones. Sealcoating every few years puts a protective layer on top that takes that damage instead.

Cold nights: cracking

With 79 freezing nights a year, Victorville gets real freeze-thaw cycles. Asphalt that was soft at 4 p.m. turns stiff by sunrise. Water from a winter storm or a sprinkler line gets into cracks, freezes and pushes them open. Cracks that are sealed before winter stay small; cracks that are left open grow into potholes.

Wind and sand

The city's records note that high wind events occur all year and especially in spring, sometimes knocking down power lines and kicking up dust storms. For paving, wind matters in three ways. Sand blown onto a prepared base or tack coat weakens the bond between layers, so we clean right before paving. Sealer needs calm air, or it picks up grit. And during the job, the Mojave Desert Air Quality Management District's fugitive dust rule bars dust that stays visible beyond the property line and requires reasonable precautions to keep dirt off public roads, so we water and sweep as we go.

A base that does not move

Residential asphalt is commonly built as 2 to 3 inches of compacted asphalt over 6 to 8 inches of compacted gravel base, according to HomeGuide's cost guide, with thicker sections for heavier vehicles and 4 inches or more for commercial lots. Victor Valley soil varies a lot from lot to lot. Loose, sandy ground needs to be compacted and sometimes stabilized; old fill around newer homes can settle; and hard caliche layers can make grading slow. We check the ground first and build the base for what we find.

Growth means traffic

Victorville grew from 14,220 people in 1980 to 134,810 in 2020. Much of the newer growth across the region is tied to logistics, and the Southern California Logistics Airport now occupies part of the former George Air Force Base. Trucks are a bigger part of local traffic than they used to be, and commercial lots, yards and entrances need heavier sections than they once did.

Who handles the street side

The City of Victorville requires an encroachment permit for work in the public right-of-way, applied for through the city's Citizen Access portal. Neighboring Apple Valley, Hesperia and Adelanto have their own processes, and San Bernardino County issues encroachment permits, including for driveway approaches, on county-maintained roads in unincorporated areas. If your project touches the apron or the street, we tell you who issues the permit before scheduling.

We work in Victorville, Apple Valley, Hesperia and Adelanto, plus Spring Valley Lake, Oak Hills, Phelan, Pinon Hills, Helendale, Oro Grande, El Mirage, Lucerne Valley and out to Barstow and Lenwood, with some mountain work in Wrightwood, Crestline and Lake Arrowhead. Conditions change a lot across that area. Phelan and Pinon Hills sit near or above 4,000 feet; Wrightwood is above 6,000 feet and averages about 62 inches of snow a year; Barstow and Helendale are lower and hotter. The permit authority changes too: four incorporated cities and towns plus San Bernardino County for the unincorporated communities. Each town page covers what applies there.
