OTTA SEAL TRIALS IN KWAZULU-NATAL, SOUTH AFRICA

Due to difficulties in sourcing good quality gravels in some parts of KwaZulu-Natal Province, the blacktopping of low volume gravel roads is currently being considered there. Traditional chip seals are used extensively in the Province to upgrade gravel roads to surfaced standard. However, the high cost of the seals cannot be justified for gravel roads carrying less than 500 vehicles/day. Otta seals have been successfully used in many countries as low cost surfacing alternatives for low volume roads. This paper summarizes observations on the performance of Otta seal trial sections constructed on a low volume gravel road outside the city of Durban on the eastern coast of South Africa.
