Monache High School Parking Lot and Solar Panel Installation, Porterville, CA. The district facility director commented that the cost of the concrete was more expensive than 3” of asphalt but paid for itself in 10-15 years.

The Concrete Solution for Parking Lots
Concrete parking lots offer excellent performance compared to asphalt pavements. A variety of textures and color enhancement can add to the value of parking areas for retail, commercial and residential building owners. Long recognized for its durability and strength, concrete requires much less maintenance than other materials and provides environmental benefits including lower energy costs for lighting, enhanced safety, can be recycled, and is cost effective. Concrete parking lots will continue to pay dividends for years to come!
Benefits of Using Concrete for Parking Lots
• Concrete pavements can carry heavy loads without rutting or developing potholes.
• Concrete’s rigidity and high strength provide the same load-carrying capacity in a thinner section than traditional paving materials.
Concrete surfaces are much lighter in color, meaning that lighting costs can be reduced—you can eliminate 3 of 10 light fixtures and still have the same level of lighting, according to the National Ready Mixed Concrete Association. This creates a safer parking lot and also reduces energy costs.
Concrete parking lots are sustainable—stormwater runoff has low toxicity, the pavement surface is cooler and friendlier than dark pavements, and the concrete can incorporate recycled materials such as fly ash or slag. LEED credits are available for these items. (fly ash, slag,).
The lighter color also results in a lower temperature for the parking area, reducing the heat-island effect and lowering cooling costs for adjacent buildings. Ambient air temperatures above a concrete parking lot can be as much as 10° cooler than an asphalt lot.
• Maintenance costs for concrete parking lots are small to nothing. This means no business or public interruptions, and no unexpected maintenance costs that asphalt pavements require.
• Concrete parking lots can be colored and textured.
