Team Lab base stabilization
Case Studies
Lake Eunice Township was looking for a solution for a section of gravel-surface road that connects two north- and southbound bituminous-surface roadways. This section of Deroxe Road is 26 ft wide and 1.1 miles long and has an average daily traffic of 150. This road is the only east- and westbound...
EJ Case Study
Case Studies
A section of roadway in Huntington, N.Y., was prone to flooding. Officials with the New York State Department of Transportation (NYSDOT) had a plan to eliminate the significant ponding, but they had difficulty finding a partner to supply the grates and frames for their “extreme” trench-system...
Concrete road construction
Case Studies
It isn’t often you will hear a contractor say productivity is not important. In the case of road-repair projects, the urgency to complete the work is even greater. It’s the reason an 18-month road-repair project in Cuyahoga County, Ohio, required an extra push from one local concrete crew and a...
Asphalt manhole covers
Case Studies
Where Fort Street runs through Detroit's heavily industrialized southwest side, a section of it immediately adjoins a huge Marathon Oil Co. refinery. The major roadway carries a great deal of heavy truck traffic, including semitrucks hauling steel—and yet some infrastructure under the street still...
Rankin Bridge
Case Studies
Originally built to accommodate streetcars and rising automobile traffic six decades ago, the historic Rankin Bridge has long served as a critical access point to Pittsburgh’s large steel industry. Today, the four-lane, 505-ft-long cantilever bridge—a steel superstructure resting 75 ft above the...
Nebo Loop Scenic Byway
Case Studies
