Upgrade of highway roadside drainage

TILTEX 7 was specified by the Hawaiian Department of transport for a highway roadside  drainage upgrade project.

Due to ease of application to existing road infrastructure compresive strength and hot asphalt road surface TILTEX 7, was the most cost effective and best quality choice to deliver a fast, strong drain application next to a major government highway before wet seasons commenced.

TILTEX 7 installation had minimal traffic disruption with less equipment requirement at the roadside than with traditional concrete drain lining methods, which can add complexity and risk of safety and visibility hazards for vehicles and construction workers.

The project was completed ahead of schedule with impressive 50MPa compressive strength results after 24 hours.

Further TILTEX 7 applications will include the erosion control of the adjacent steep slopes and seal form a part of the slope stabilization program.
