Study of Stone Matrix Asphalt For The Flexible Pavement

Stone Matrix Asphalt Pavement is hot mix asphalt consisting of two parts - a coarse aggregate skeleton and a binder rich mortar. It is made up of a mixture of crushed coarse and fine aggregates, mineral Filler, asphalt cement and a stabilizer for the binder, such as polymer or fibres.

Characteristics of stone matrix asphalt by using natural ...

Jan 01, 2019  The Stone Matrix Asphalt (SMA) mixtures provide a durable wearing course in the flexible pavements. This research is to study the influence of additives on the characteristics of SMA mixtures and to propose an ideal surface course for the pavements. The additives used for this investigation are natural fibres such as coir, sisal and banana fibres.
