Why Do Expansive Clay Soils Cause Parking-Lot Heaving Across the Pikes Peak Region?
June 22, 2026
Expansive clay soil heaving in the Pikes Peak region is the upward displacement of parking-lot pavement caused by moisture-sensitive clay minerals in the subgrade that swell when wet and shrink when dry. The Pierre Shale and Dawson formations underlying much of Colorado Springs contain montmorillonite, smectite, and illite clays capable of generating forces that far

What Is Asphalt Milling and When Is It Needed?
April 9, 2025
Over time, asphalt surfaces degrade due to continuous vehicular load, environmental exposure, and oxidation. Surface distress, manifesting as alligator cracking, rutting, ravelling, and pothole formation, compromises both structural integrity and safety. When conventional patching fails to provide a sustainable solution, asphalt milling emerges as the most efficient method for surface rehabilitation. Asphalt milling, also known
