Eliminator® system protects and prolongs life of Yunnan Kunming Kunluo Road Interchange.

Project Overview

The Yunnan Kunming Kunluo Road Interchange is a steel bridge deck in China that required a high performance waterproofing material to protect and prolong the life of the structure. After reviewing various pavement specifications, a decision was made by the client to use the Eliminator spray-applied bridge deck waterproofing system with a pavement layer made up of two layers of SMA.

Product Selection

Chosen for the job was Stirling Lloyds Eliminator spray-applied bridge deck waterproofing system with a pavement layer made up of two layers of SMA. The combination of Eliminator and SMA provides the structure with thermal stability, and excellent crack bridging properties.

A vital requirement during the waterproofing of the Yunnan Kunming Kunluo Road Interchange was that the use of Eliminator and SMA would allow for a faster and easier construction process than traditional measures to help reduce construction times on site.

The Eliminator system is industry proven having protected structures around the world in the most extreme climates. The cold-spray applied system is fast, effective and able to seal complex, critical details and penetrations with ease. Eliminator forms a tough, flexible and seamless membrane with no vulnerable joints to outlast the design life of the structure and reduce maintenance costs.

The Application

The pavement specification of Eliminator and two layers of SMA asphalt were successfully applied to the Yunnan Kunming Kunluo Road Interchange. Technical Guidelines for design and construction of deck pavement on steel box Bridges requires an adhesive strength between the asphalt waterproofing layer and steel to be ≥ 1.2Mpa. However, test data shows the use of Eliminator on steel bridge decks to be in excess of ≥ 5.0Mpa.

Summary

The use of Stirling Lloyds Eliminator waterproofing system with a pavement layer made up of two layers of SMA enabled the Yunnan Kunming Kunluo Road Interchange project to be carried out with speed to reduce construction time as per requirements. The Eliminator system has ensured that the busy interchange will be well protected for the long-term.
