Highway Shoulder Stabilization Saskatoon Canada | T-PRO®

Highway Shoulder Stabilization Saskatoon Canada | T-PRO®

Project Overview
Lithic Industries applied T-PRO® polymer soil stabilization to road shoulders along Highway 16 near Saskatoon, Canada. A 1.5-meter-wide shoulder section was treated intermittently between paved asphalt segments to prevent aggregate displacement, edge softening, and surface deterioration caused by vehicles drifting off the main roadway. Different polymer concentrations  were tested and matched to varying levels of wear from traffic, precipitation, and shoulder shoving.

Project Objectives
The primary goals were to improve shoulder strength, enhance wear resistance, and ensure long-term motorist safety. The treatment needed to deliver reliable performance under Canadian weather conditions while providing a cost-effective alternative to traditional shoulder repairs.

The Challenge
Road shoulders along Highway 16 experienced frequent shoving of aggregate, edge softening during rain, and surface deterioration from vehicles pulling off the road. This created hazardous conditions for trucks and cars, especially on curved sections, and required frequent and costly maintenance.

The Polymer Soil Stabilization Solution
Lithic Industries applied a targeted T-PRO® polymer soil stabilization approach using the existing in-situ shoulder material. The polymer was infused directly into the shoulder at targeted concentrations. After compaction, a topical seal coat was applied over the entire treated. This created a strong, water-resistant polymer-stabilized shoulder with significantly improved shear strength and surface durability.

Proven Results
The T-PRO® treatment delivered clear, measurable benefits:

- Dramatically improved shoulder stability and wear resistance
- Reduced aggregate displacement and edge softening
- Enhanced motorist safety by maintaining consistent shoulder integrity
- Demonstrated a cost-effective, long-term, low-maintenance alternative to traditional shoulder repairs
- Superior performance in high-traffic highway conditions

Application Details

- Equipment Used: Milling Machine, Grader, Water Truck with Pressurized Spray Bar, Vibrating Pneumatic Roller
- Application Method: Infused polymer at concentrations + topical seal coat
- Topical Seal Coat Rate: 115 ft² per gallon

Maintenance Requirements
Maintenance is simple and cost-effective:

- Remove any loose material from the shoulder surface
- Apply a light topical re-coat of T-PRO®  

Why Highway Agencies Choose T-PRO® for Shoulder Stabilization
This project demonstrates how modern polymer soil stabilization provides reliable, low-maintenance performance for highway shoulders and edge treatments. It is an ideal solution for transportation departments seeking to improve safety, reduce maintenance frequency, and extend the life of road shoulders using in-situ materials.

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 existing on-site materials while improving shear strength and water resistance.
