EXPERIMENTAL STUDY ON BEHAVIOUR OF FIBER REINFORCED CONCRETE AND FLY ASH FOR RIGID PAVEMENTSJayant Virat and Humaib Nasir
A pavement being a layered structure on which vehicles travel serves mainly two purposes, i.e. firstly to provide a comfortable and durable surface for vehicles and secondly to reduce stresses on underlying soils. It has been found over past years that concrete pavement has some deficiencies as low tensile strength, low post cracking capacity, brittleness and low ductility, limited fatigue life, thereby becoming not capable of accommodating large deformations, low impact strength. Apart from it Cement concrete pavements are characterized by brittle failure and complete loss of loading capacity, once failure is initiated. Thereby it is very essential to research about of an alternative material which satisfies required facilities. In this research, Micro fibers and flyash have been used instead of cement in different proportions for preparation of fiber fly ash pavements and its properties have been verified on casting cubes of it. An attempt is made by performing experimental tests to verify their tensile and compressive strengths which have been compared with normal PPC blocks to highlight the differences in both the cases.
