Abstract

In this case study Car Mounted Bump Integrator (CMBI) is a method involved in measuring roughness value of the pavement at Shettihalli – Ichalakaranji Road SH-78 from Km 23.75 to Km 53.37 in Hukkeri & Chikkodi Taluk of Belagavi District Package 415, Karnataka State, India. For the present study, the roughness was measured using Car Mounted Bump Integrator linked to software to be controlled by operator from a laptop computer in the survey vehicle. The International Roughness Index (IRI) is a metric for determining how smooth or rough a pavement is. The smoother the pavement rides, the lower the calculated IRI. The harder the pavement rides, the higher the IRI. The IRI is commonly expressed in meter per kilometer, inches per mile, or millimeter per kilometer. IRI is now a widely used international roughness evaluation index that has the advantages of scientifically measuring pavement smoothness while avoiding human error. It's the first smoothness index that can be utilized in a variety of pavement smoothness devices, and it's backed up by a set of program software for calculating the IRI value
