California’s asphalt industry supports everything from residential developments and commercial parking areas to airports, city streets and major highways. The right company must do more than supply hot mix. Reliable plant access, technical mix design, paving equipment, recycling capability and experience with public-agency specifications all affect project quality.
This ranking focuses on established asphalt producers and paving contractors with meaningful California operations. The companies were compared on plant coverage, construction experience, material range, technical capability and suitability for large infrastructure work.
1. Granite Construction – Best Overall Asphalt Company
Granite Construction is headquartered in Watsonville and works on highways, bridges, airports and other public and private infrastructure. It was ranked No. 1 in the highways category of Engineering News-Record’s 2025 Top Contractors list for the fifth consecutive year.
Its asphalt range includes hot mix, warm mix, cold mix and products containing reclaimed asphalt pavement. Granite can also develop agency-approved or custom mixes for projects with demanding technical specifications.
The company operates numerous California asphalt facilities, including plants in Bakersfield, Sacramento, Santa Clara, Salinas, Pleasanton, Coalinga, Santa Paula and other markets. This plant network supports both material supply and Granite’s own paving operations.
Why Granite Construction Is Popular
Granite can manage a project from aggregate production and asphalt design to paving and final construction. This integrated approach is valuable for highway agencies, municipalities, airports and large developers that need one contractor to accept responsibility for several project stages.

2. Teichert – Best for Northern California Infrastructure
Founded in 1887, Teichert builds highways, subdivisions, commercial sites, airports, water infrastructure and renewable-energy projects. The company states that it has constructed thousands of miles of roads and highways throughout California.
Teichert Materials produces asphalt, aggregates and concrete, while Teichert Construction handles grading, underground utilities, paving and related site work. Its vertically integrated supply chain gives the company greater control over material quality, scheduling and delivery.
The company employs more than 3,000 skilled workers and operates over 700 pieces of construction equipment across its site-development activities.
Why Teichert Is Popular
Teichert is especially strong in Northern and Central California, where it has longstanding relationships with public agencies, developers and contractors. It can supply asphalt to other builders or manage the complete road and site-development contract.

3. Graniterock – Best for Asphalt Recycling and Pavement Preservation
Graniterock has served California since 1900 and installed the state’s first hot-mix asphaltic concrete plant in 1935. Its asphalt range includes hot mix, reclaimed asphalt pavement, road oils, emulsions and patching materials.
The company also provides spreader-truck delivery, logistics, construction and pavement-preservation services. Its Pavement Recycling Group gives customers options for rehabilitating existing roads and reusing old pavement instead of removing and replacing every layer.
Why Graniterock Is Popular
Graniterock has deep knowledge of Northern California road conditions and public-works requirements. Its mix of asphalt production, recycling and construction is particularly useful for resurfacing projects where extending pavement life is more practical than full reconstruction.

4. Vulcan Materials Company – Best for Large-Scale Material Supply
Vulcan is the largest producer of construction aggregates in the United States and also supplies asphalt in California. Its asphalt operation produces mixes for projects of different sizes and provides customers with facility-search, quantity-calculation and safety-information tools.
The company’s strength begins with aggregates—the crushed stone, sand and gravel that make up most of an asphalt mixture. Control over aggregate production can improve supply reliability when a project requires large and continuous quantities.
Why Vulcan Materials Is Popular
Vulcan is widely used for high-volume material requirements. Contractors working on highways, industrial sites and large developments value its production capacity, reserves and ability to deliver consistent materials at scale.

5. CalPortland – Best for California Central Coast Projects
CalPortland produces hot mix and warm mix asphalt for transportation, commercial and residential projects. Its California asphalt operation is centred around the Santa Maria and Central Coast market.
The company can also provide aggregates and construction services, including roadway work, earthwork and site development. Its warm-mix products are important for projects seeking lower production temperatures and more sustainable paving methods.
Why CalPortland Is Popular
CalPortland is practical for Central Coast customers who need asphalt supply, technical guidance and construction capability from the same organisation. Its broader materials network also supports projects requiring concrete, aggregates and cement.

How to Choose the Right Asphalt Company
Granite is the strongest all-round choice for major paving and infrastructure work. Teichert is particularly well established in Northern California, while Graniterock stands out for recycling and pavement preservation. Vulcan is strong in large-volume material supply, and CalPortland is well positioned for Central Coast projects.
Before awarding a contract, compare the asphalt specification, estimated tonnage, base preparation, compaction method, drainage work, project schedule and warranty. The quotation should clearly state whether milling, hauling, striping, traffic control and disposal of old pavement are included.
FAQs
Q: What is the difference between hot mix and warm mix asphalt?
A: Hot mix is produced and placed at higher temperatures. Warm mix uses technologies that allow production at lower temperatures, which can reduce fuel consumption, fumes and emissions while sometimes extending the paving season.
Q: Can reclaimed asphalt be used on a new road?
A: Yes. Reclaimed asphalt pavement can be processed and added to a new mix when permitted by the project specification. The approved percentage depends on performance requirements and agency rules.
Q: Why is asphalt-plant location important?
A: Asphalt must normally reach the job site while it remains within the correct temperature range. A nearby plant can reduce transportation time, improve scheduling and limit the risk of the material cooling before placement.
Q: Should a private customer hire a producer or a paving contractor?
A: Homeowners and small businesses normally need a licensed paving contractor that handles preparation, placement and compaction. Asphalt producers mainly sell material and may not accept small driveway projects directly.
