I-310 ASPHALT PAVING PROJECT
About this Project

Date: 2020

Client: Louisiana Department of Transportation and Development (LA DOTD)

Project Type: Concrete and Asphalt Paving
Boh Bros. Construction Co. reconstructed a heavily used 11.7-mile stretch of I-310 from I-10 to U.S. 90 in St. Charles Parish. Work began by patching some 4,900 square yards of concrete panels. The crew cut panels to full depth, removed existing concrete with a hydraulic hammer, drilled and doweled into the existing concrete, and placed new concrete.
Once patching was complete, Boh paved the 11.7 mile stretch on I-310 with some 17,000 tons of hot mix asphalt and 1,100 square yards of asphalt patching. A majority of the work called for a 2-inch cold plane and a 2-inch Level 2F Superpave asphalt overlay (a high friction course which is a state standard), with some 4-inch asphalt paving along the center cable barrier and at the new guardrail locations.
Boh produced the entirety of the asphalt at its France Road plant and leaned on its CMEC-certified lab to ensure that the material met specifications. On-site, a QC technician ensured that quality was maintained as Boh’s paving crew laid the asphalt using a Caterpillar 1055F Series paver, Weiler material transfer vehicle, and compactors.

Avondale Marine Project
Boh Bros. assisted Avondale Marine in rebuilding Dock No. 2 so that Host can use the dock’s existing pile–supported ship ways to construct a suspended roadway. Once operational, trucks will be able to carry heavy loads from dock to land, and vice versa, as the roadway will have a 100-ton capacity.
Lake Pontchartrain Causeway Safety Bays CMAR Project
The Greater New Orleans Expressway Commission (GNOEC) sought to improve the safety of the 23.83 mile Lake Pontchartrain Causeway Bridges by adding shoulders and emergency pullover areas on both spans. The GNOEC chose a Construction Management at Risk (CMAR) delivery method for a solution to meet their stated goals.
