Bridges

Introduction

Structural Lightweight Concrete

Structural lightweight concrete is being used in bridge decks with ever increasing frequency. New as well as rehabilitated structure designs are incorporating lightweight concrete. Cost effective because of reduction in reinforcing steel, dead loads and foundation requirements coupled with the excellent durability and skid resistance of lightweight concrete.

Norlite has been involved with numerous bridges over the past years and expect to participate in the massive rehabilitation of deteriorated bridges in our area for many years in the future.

If weight is not a problem, just consider the increased cover of concrete over re-bar that lightweight concrete can afford the designer.

Superior durability, excellent resistance to freeze-thaw and improved skid resistance are some of the prime reasons for the increased use of lightweight concrete in bridge construction. The use of lightweight concrete for restoration allows the engineer to use an existing substructure or superstructure in combination with lightweight concrete to ultimately increase live load capacity of the structure.
