Case Study

Solar Farm Dust Control Phoenix Arizona | T-PRO®

Project Overview
Lithic Industries supplied T-PRO® polymer soil stabilization for dust control on a newly constructed gravel access road serving a major photovoltaic solar energy plant in Phoenix, Arizona. The high-traffic unpaved road was engineered to perform reliably under extreme heat and heavy construction traffic while meeting strict environmental requirements.

Project Objectives
The primary goal was to provide robust fugitive dust control during an 18-month construction phase that generated over 70,000 heavy truck movements, while maintaining full bearing capacity through both hot summer and cooler winter conditions.

The Challenge
Heavy construction traffic on imported Class II base material in a high-heat, arid environment rapidly generated significant airborne dust. Uncontrolled particulate emissions created safety hazards, environmental compliance issues, and increased maintenance demands. The road needed reliable all-weather performance without compromising drainage or structural integrity.

The Polymer Soil Stabilization Solution
Lithic Industries applied a targeted T-PRO® polymer soil stabilization approach using the existing in-situ materials. The road surface was graded and moisture-conditioned, then treated with a topical polymer seal coat that locked down fines and created a durable, dust-resistant wearing course.

Proven Results
The T-PRO® treatment delivered strong performance under extreme conditions:

- Excellent fugitive dust control under intense heavy-truck traffic (70,000+ movements)
- Maintained full road surface integrity and bearing capacity in varying seasonal conditions
- Supported the project’s environmental goals by minimizing particulate emissions
- Cost-effective, low-maintenance solution tailored to the 18-month construction timeline
- Carbon-neutral chemistry with no negative impact on surrounding flora

Application Details

- Equipment Used: Grader, Water Truck with Spray Bar, Smooth Drum Roller
- Application Method: Topical polymer seal coat with in-situ stabilization
- Initial Coverage Rate: 70 ft² per gallon
- Maintenance Rate: 200 ft² per gallon quarterly as needed

Maintenance Requirements
Maintenance is simple and cost-effective:

- Remove any loose material from the surface
- Apply a light topical re-coat at 200 ft² per gallon as needed

Why Solar Developers Choose T-PRO® for Site Access Roads
This project demonstrates how modern polymer soil stabilization provides reliable, low-maintenance dust control and road performance for large-scale solar energy construction. It is an ideal solution for developers seeking to protect panel efficiency, meet environmental requirements, and reduce long-term site maintenance costs.

T-PRO® is a proven, carbon-neutral polymer soil stabilization technology backed by Texas A&M Transportation Institute (TTI) validation. It consistently delivers strong, long-term results using in-situ materials.
