Lafarge Delivers Night Paving Solution

Coordinated milling and paving operations prove to be best approach for resurfacing Boulder's historic Pearl Street Mall project.


  • Since the Loop is the only access to downtown businesses, including restaurants and night clubs, special sequencing of night work was required to provide roadway access to these businesses.
  • Since parallel and diagonal parking line the entire project length on both sides of the roadways, no parking zones were posted 72 hours prior to each construction phase, but approximately 15 vehicles had to be relocated each night.
  • With tight urban space constraints, like center median diversion islands at each of the four primary corners of the Loop, creative construction approaches were required to meet deadlines and deliver a quality finished product.
  • Since most of the project was to be constructed during night hours, crews had to adapt to restricted visibility
  • Since the project was executed in phases, temporary full-compliance markings were required, temporary pedestrian access ramps had to be constructed and attention to site cleanliness had to be maintained at all times.
  • With concrete pavement bisecting the project, as well as some decorative concrete walkways, special attention was required to prevent tracking tack oil across these areas.
  • With so many businesses affected by the construction, advance communication prior to each phase was required to minimize any disruptions to those businesses.

“The project really came together well, and the actual milling and paving portion only lasted two weeks,” Young says. “Working at night allowed us to complete the project quicker, and that meant fewer disruptions to the businesses in the area.”
