Summary:
This paper outlines the basis of the decision to use bitumen-rubber single surface treatment as a “holding action” until
sufficient funds become available to perform the recommended rehabilitation of severely deteriorated roads.  The
surface treatments performed better than expected with no deterioration after 4 ½ years of service.  The paper provides
a cost comparison, which shows the bitumen rubber surface treatment to be cost effective.
