Project Spotlight: Chesapeake Bay Bridge-Tunnel

In April of 1964, the Chesapeake Bay Bridge-Tunnel (CBBT) officially opened to traffic after a 42-month project fondly referred to as “when men split the sea“. For more than 50 years, the CBBT has captured worldwide attention as an award-winning modern engineering marvel, crossing over and under the open waters of the Chesapeake Bay. With over 130 million commercial and passenger vehicles having crossed the Bridge-Tunnel, the incredible structure had seen it’s fair share of wear and tear.
Milling and Repaving Project
In July 2019, Allan Myers was awarded a milling and repaving project and partnered with Associated Asphalt to supply a highly modified asphalt. The project would require the milling and replacement of asphalt to level the surface from the south toll plaza and the north toll plaza in both northbound and southbound lanes.
For this particular project, we supplied 2,100 liquid tons of Highly Modified Asphalt, PG 76E-28. StellarFlex® HiMA is formulated to provide extreme resistance to permanent deformation, fatigue cracking, and thermal cracking, which prove to be common threats to asphalt durability.
Paving began in September 2019, paused from November 2019 – February 2020, and is expected to be completed in June 2020.
As a company based in Virginia, it was an honor to have the opportunity to supply asphalt to restrengthen and revitalize such an internationally recognized structure. We look forward to watching the rest of the Parallel Thimble Shoals Tunnel Project come to completion.
About StellarFlex® HiMA
Formulated to provide extreme resistance to permanent deformation, fatigue cracking, and thermal cracking, StellarFlex® HiMA is a very highly Styrene-Butadiene-Styrene (SBS) polymer-modified asphalt. Featuring three times the polymer typically found in standard polymer-modified asphalts, StellarFlex® HiMA is an ideal asphalt binder for bridge deck paving applications, or to limit cracking over concrete pavements.
