Phase 5 Erosion Control on Interstate Route H-1

Project Description

Articulated Concrete Block Mat (ACBM) System Addition

It is often challenging to maintain vegetation on the underside of a highway overpass or bridge due to the lack of exposure to sunlight and rainfall in these areas. For this site an ACBM system was designed and constructed to protect the slope from erosion. ACBM systems are a great alternative to traditional concrete for these areas because the blocks can be individually placed in an otherwise difficult to reach location. Additionally, the ACBM system can easily adjust to uneven contours and can tolerate movement and settling of the surface below, leading to longterm durability with low maintenance costs.
