VAA Virginia Asphalt Spring/Summer 2021

14 SPRING/SUMMER 2021 △ continued from page 12 Superior Paving operation’s team. Over the course of the project, several different Superior Paving crews contributed and, due to timing, used mixes from several Superior Paving plants. Other Project Challenges The project location (See Figure 1) presented challenges for trucking and logistics. Inside the beltway, east of Tyson's Corner, trucks often crawled to the job site in pre-COVID-19 traffic conditions. This made estimating a round time or relying on a consistent truck count for this area challenging. The job was 25 miles from Superior’s Centreville Plant. The project included many phased widenings where employees and trucks were in multiple lane closures. There were still a lot of active crossovers and intersections that kept truck stacking areas at a minimum. This caused us to tightly manage truck spacing and factor in traffic congestion logistics to get mix there efficiently EXCELLENCE IN THE MIDST OF CONGESTION Dark Blue = Full Depth Paving Light Blue = Mill & Overlay/Build-up Yellow = Existing Roadway Figure 4: Project Sequencing Figure 5: Paving Challenges Figure 6: Bicycle Lane without stacking up on site. As you can see, painted on the asphalt are examples of the variable depth fills needed to move the crowns on most of these roads (Figure 3). As shown in Figure 4, placing new full-depth pavements on the same area the existing asphalt roads are being used caused addi- tional phasing issues to build a half and switch, then build a half and then top all of it. Superior’s team was challenged with maintaining traffic movement over widenings and new milled surfaces.

Superior Paving Corp. was honored to be selected by the site developer The Anderson Company as its paving contractor on this project.
