Transforming Driveway Durability: CMDI’s Asphalt Reinforcement Project
At Erickson Asphalt, we strive to lead the charge in driveway installation and refurbishment trends, exemplified by our recent project with Central Minnesota Diagnostic, Inc. (CMDI). This collaborative organization connects hospitals with cutting-edge imaging technologies, but their parking lot was in dire need of reinforcement due to severe rutting from heavy semi-truck traffic.
Understanding the Early Challenges
Before diving into the solution, it's essential to understand the problem. CMDI's lot was not just another surface; it supported massive transportation vehicles on a daily basis. The issue of rutting—where the asphalt sinks and creates depressions—was primarily due to improperly supported soil, particularly clay, which is notoriously tricky to work with in the Milaca region.
The Innovative Approach to Driveway Installation
To ensure a long-lasting solution, our team began by removing ten inches of the damaged asphalt and subbase material, providing a fresh canvas for reconstruction. A geotextile fabric was then installed to reinforce the pavement foundation. This fabric’s role is vital; it prevents clay from mixing with the aggregate base, maintaining the integrity of the asphalt and ultimately preventing alligator cracking under heavy loads.
Building a Robust Foundation
The subsequent step involved crafting a new base. We utilized asphalt millings salvaged from the demolition, combined with 400 tons of class 7 aggregate to ensure the base could withstand CMDI's demanding traffic requirements. This thoughtful construction methods secure the longevity and resilience of the driving surface.
Finalizing with Quality Asphalt
Next, we laid down 650 tons of hot mix asphalt using a two-lift process. By applying asphalt in multiple layers, we achieve optimal compaction, crucial for supporting semi-trucks and ensuring minimal wear over time. The end result is a strong, durable surface that meets challenges head-on, allowing CMDI to continue their critical services unhindered.
Implications for Future Driveway Projects
Our success with CMDI underscores crucial trends in driveway installation, especially in commercial settings. Homeowners and property managers can learn from these innovative methodologies, especially when dealing with challenging ground conditions. The installation of geotextile fabrics and multi-layer asphalt applications could revolutionize how we approach high-traffic areas in both residential and commercial driveway refurbishment.
If you're considering a driveway installation or refurbishment, be sure to explore the latest innovations and consult with expert contractors who understand the evolving material technologies. A robust and durable driveway not just enhances curb appeal but also adds significant long-term value to your property.
