AN EXPERIMENTAL USE OF SISAL FIBER IN HOT MIXED PAVEMENT

Abstract

The increase in traffic growth and maintenance expenditures demands the urgent need for building better,
long-lasting, and more efficient roads preventing or minimizing bituminous pavement distresses. The Sisal fiber mixtures
provide a durable surface course. In order to improve the performance for a pavement surface, the fiber additives in
flexible pavement mixture were compared. Furthermore, certain groups of comparative experiments were conducted by
adding the different length and different quantity of the sisal fiber toward the flexible pavement mixture by conducting
various test and showing that the sisal fiber is good additive to improve performance for pavement surface. The best
length and the best quantity of the sisal fiber in the flexible pavement mixture were determined and its application is very
limited mainly due to the lack of proper specifications.
