AIT Bridges builds corrosion-resistant structures. This innovative construction uses hollow composite arches that are filled with concrete on-site to serve as the main structural supports of a bridge. The arch shell acts as an external reinforcement layer but also protects concrete from harmful environmental and corrosive elements lowering future maintenance costs of the structure. Design code for composite arch bridges was published by AASHTO in January of 2013.
The AASHTO design code coupled with numerous constructability improvements and competitive pricing has made composite arch bridges a compelling alternative to traditional precast or steel crossings.
