"The use of RAP (Reclaimed Asphalt Pavement) in hot mix asphalt materials has become a common practice in several countries. This effect becomes maximized when subgrade layer is mixed with underneath unbound granular layer which yields poor drainage followed by stiffness degradation and finally reduce stability. Rosli Hainin1, Wasid Farooq Reshi1, Hamed Niroumand, “Properties of Stone mastic Asphalt and Stone Mastic Asphalt Composition” in 2012, pp.49-56. Since then, because of its excellent performance characteristics, the use of SMA increased in popularity amongst the road authorities and asphalt industry. Rutting occurs only on flexible pavements as indicated by permanent deformation or rut depth along wheel load path. Sadek Sinan. Heavy duty performance is usually enhanced with polymers and fibers, this helps to provide a thick aggregate coating to the aggregate, and the prevention of drain down during the transportation and placement. Types of Failures of Flexible Pavement Flexible pavement consist of different layers such as, Sub-grade Sub-base course Base course and Surface course If any one of the above mentioned layers becomes unstable or weak then it will result in failure of flexible pavement. Fibers • Plasticity index of soil depends chiefly on clay content in soil. • Even though SMA has a higher cost than conventional dense mixes, approximately 20 to 25 percent, the advantages of longer life (decreased rutting and increased durability). TYPAR Geosynthetics pipeline and utilities products provide protection, location, and demarcation solutions for civil engineering applications. As plasticity index is a product of these limits, consistency limits together with other indices including plasticity index, can be used to classify fine-grained soils to be used for engineering construction.
