Comparison of properties of stone matrix asphalt with cellulose fiber and coir fiber

The stone matrix asphalt (SMA) mix is a hole reviewed mix that is portrayed by utilizing high coarse totals, high black-top substance and fiber segments as stabilizers. Due to stone-to-stone contact and presence of high filler content, it acts as a stiff matrix and is best suitable for high volume roads and urban intersections where braking effects are more. In general, cellulose fibers are added in SMA mixes to avoid oozing of bitumen from the mix. In the present study, in addition to the cellulose, coir fibers will be added to the SMA mixes and its properties will be evaluated. Since, the coir fibers are easily available in India and comparatively cheap, it is decided to use in the current investigation. Itemized research facility examinations will be done by getting ready black-top solid combinations by adding two sorts of filaments (cellulose and coir) with measurements of 0.3%, 0.4% and 0.5% by weight of total mix. Volumetric properties of the mixes will be determined and various strength tests such as marshal stability will be conducted. Based on above tests ends will be drawn on appropriateness of coir filaments instead of cellulose strands.
