Investigation of Strength Properties of Grouted Concrete Pavement as Rigid Pavement Material for Low Volume Roads Using Non-destructive Test

Although India's road system has significantly improved over the past three to four decades, more attention still has to be paid to connectivity in the nation's rural areas. The Pradhan Mantri Gram Sadak Yojana (PMGSY) was established by the Indian government to build the country's rural interior roads. This Yojana focuses on labor-incentive, low-cost technologies for the long-term growth of traffic network in rural regions of India. Such an investigation is carried out in this study. In the present study strength properties of grouted concrete pavement as rigid pavement material to be used in low traffic regions of India are evaluated. The strength characterization of the grouted concrete is evaluated using Non-destructive test methods such as Ultrasonic Pulse Velocity test (UPV) and Rebound Hammer Test. A total of 6 samples of grouted concrete macadam were tested for UPV and Rebound hammer test for a curing period of 28 and 56 days. Based on UPV and Rebound hammer test it was concluded that 4 out of 6 mixes give most favorable strength properties and can be used as rigid pavement in low traffic regions.
