Fly ash is a huge waste available at thermal power plants in the country. Large consumption of fly ash in paver blocks will help the nation to make economical paver blocks and will address challenges associated with environmental issues and disposal of waste In the present study on M35 grade paver blocks with thickness 60mm and 80mm with replacement of OPC by 30 fly ash and addition of polypropylene fibre 0.0 to 0.5 with increment of 0.1 by weight of cement have been manufactured to access the suitability for Indian road surfaces for different applications. The blocks have been tested at the age 7 and 28 days for strength and durability criteria. For strength properties compressive strength and flexural strength test were conducted, both being important for applications for road surfacing. For durability properties water absorption has been studied. The result of compressive strength and flexural strength indicates that it is feasible to use OPC replaced by 30 fly ash and addition of 0.3 PPF in manufacturing of paver blocks. Paver blocks have attained target compressive strength and flexural strength at 28 days in all the grades.
