ESTUDO DO BAGAÇO DE CANA DE AÇÚCAR COMO ADITIVO EM SMA

Abstract

The Stone Matrix Asphalt (SMA) is an effective alternative for raising pavement performance. A characteristic of the SMA mixtures is the high content of asphalt binder. Therefore, fat spot and segregation may come up, when mixing and placing SMA. Fibers are used to avoid that. The production of sugar and alcohol generates about 270 kg of bagasse per ton of sugarcane crushed. Most of bagasse is burned in power plants to produce thermal or electric energy. A study on applying sugarcane bagasse fibres as a stabilizing additive for SMA mixtures is here shown. Laboratory tests and experimental road section measurements were carried out. Results show that by using fibres of sugar cane bagasse, SMA draindown may be controlled and deflections of the road section were reduced.
