VAA Virginia Asphalt Spring/Summer 2021

12 SPRING/SUMMER 2021 lanes for future developments. Superior Paving Corp. was honored to be selected by the site developer The Anderson Company as its paving contractor on this project. Project Scope Bidding on this project began in 2014, and construction finally took off in the winter of 2017. The Anderson Company had many challenges to tackle before paving with demolition and utility construction for the better part of 2018. Paving work began in the fall of 2018 and was completed in the late fall of 2019. The project included multiple mobilizations to work on smaller segments in a very structured phased plan. Early on, the new roadways South Dartford and New Colshire Drive were built out of traffic, consisting of approximately 1,000 linear feet of roadway connecting Dolley Madison Blvd and Anderson Road. After that, the project transitioned into increasingly complex phases. For instance, the existing Colshire Drive had to be realigned while under traffic using daily lane closures between 9:30 am and 3:00 pm. During this time, all access to the Metro station, office complexes, high-density apartment buildings, heavy vehicular traffic, and pedestrian traffic had to be maintained. Most days, both a milling and paving crew were required to be on site. The crews worked together in small work zones to transition new paving into existing entrances and side roads and profile mill existing roads to relocate crowns and maintain drainage. Connect- ing existing intersections with new roads provided ample opportu- nity to pull string and perform variable depth paving as well as variable depth profile milling to get proper elevations and flow lines. Some of these were incremental fills up to 20-inches in depth to allow traffic to keep utilizing the intersection. Some of the milling was up to 4-inches in depth and required milling tie-ins daily to maintain traffic. In total, Superior Paving Corp. placed approximately 11,000 tons of asphalt, 6,181 tons of BM-25.0A, 2,601 tons of IM-19.0A, 2,218 tons of SM-9.5D, and approximately 4,360 square yards of profile milling.
