However, the major problem in applying this

friction course to elevated concrete roads is to accommodate the expansion joints of these structures.

On

the Island Eastern Corridor the joints have been covered using a buried joint system not previously used in Hong Kong. The durability of this system and the adhesion of the friction course to the old concrete surface will need to be monitored. for a longer period before any extension

of the trial can be considered.

On many of our roads the application of friction course is being used as an overlay to improve skid resistance. The future use of friction course to reduce traffic noise in addition to improving skid resistance will be more actively pursued once the present trial section on the Island Eastern Corridor has proved to be

successful over a sufficient period of time.
