This process is crucial for rehabilitating deteriorated pavements by removing distressed material while maintaining the original elevation and drainage patterns. We utilize advanced milling machines equipped with automated grade and slope controls, ensuring a consistent removal depth across the entire project area, which is vital for a smooth, stable base for subsequent paving layers.
Our approach to milling starts with a thorough site assessment to determine the pavement's current condition, the required removal depth, and any specific drainage considerations. We mark out utility covers, manholes, and other obstructions to ensure they are either milled around or adjusted appropriately. The milling machine then systematically removes the asphalt, which is simultaneously collected by a conveyor system and loaded directly into dump trucks for recycling. This continuous operation minimizes disruption and maximizes efficiency on site.
For Lafayette’s climate, where freeze-thaw cycles and heavy snow loads can accelerate pavement deterioration, proper milling is foundational to long-term pavement performance. Removing fatigued asphalt prevents reflective cracking from propagating through new overlays, which is a common issue when simply paving over existing damage. Milling also allows us to correct significant surface irregularities and improve drainage, which is critical for managing snowmelt and heavy rains typical in the Front Range, preventing water from infiltrating and compromising the sub-base.
Homeowners often ask about the dust and debris generated during milling. We employ water suppression systems on our milling machines to control airborne dust, and our crews perform thorough site cleanup, including sweeping and vacuuming, immediately after milling operations are complete. This ensures the work area is left clean and ready for the next phase, minimizing impact on surrounding properties. We also coordinate closely with local authorities for traffic management plans, especially for projects on public roadways or high-traffic areas.
After milling, the exposed surface, often referred to as a 'milled surface' or 'cold-planed surface,' is swept clean of all loose material and debris. A tack coat, a thin layer of asphalt emulsion, is then applied to this clean, milled surface. This tack coat acts as a bonding agent, ensuring a strong, monolithic connection between the old, milled pavement and the new asphalt overlay, which is essential for the structural integrity and longevity of the rehabilitated surface.
Asphalt milling is not just about removing old pavement; it's about strategic pavement management, especially in Lafayette. The city's expansive clay soils can lead to differential settlement and cracking, and the freeze-thaw cycles common in Colorado contribute to fatigue cracking and potholes. Milling allows us to remove these distressed layers without disturbing the underlying sub-base, which is often stable but simply needs a new wearing course.
This method is significantly more cost-effective and environmentally friendly than full-depth removal and replacement. By milling, we reduce the amount of new aggregate and asphalt binder required, and the milled material is 100% recyclable, often used as recycled asphalt pavement (RAP) in new mixes. This reduces landfill waste and the demand for virgin materials, aligning with sustainable construction practices.
Crucially, milling maintains existing curb reveals and drainage patterns. In Lafayette, where established neighborhoods have specific drainage infrastructure, preserving these elevations prevents costly modifications to adjacent concrete work or landscaping. It also ensures that water continues to flow correctly into storm drains, mitigating localized flooding and preventing water from undermining the pavement structure.
We conduct a detailed assessment of the pavement condition, identify areas for milling, and mark all utilities, drainage structures, and project boundaries. This ensures precise removal and avoids damage to subsurface infrastructure.
Our milling machines precisely remove the specified depth of asphalt using automated grade and slope controls, creating a consistent, textured surface. The removed material is immediately loaded into trucks for recycling.
After milling, the entire area is thoroughly swept and cleaned of all loose debris, dust, and foreign material. This clean surface is critical for proper adhesion of the new asphalt overlay.
A uniform layer of asphalt emulsion (tack coat) is applied to the milled surface. This critical step ensures a strong, monolithic bond between the old pavement and the new asphalt layer, preventing delamination.
