Evaluation of Structural and Functional Performance of Interlocking Concrete Block Pavement and Flexible Pavement

In several nations, interlocking concrete block pavement (ICBP) is one of the paving technologies employed. Flexible pavement is a widely used pavement type that is prevalent in most countries. The current work aims to evaluate the structural and functional performance of the existing ICBP and flexible pavement, which are laid continuously for similar traffic conditions and age. The study road is a section of a national highway with heavy and frequent traffic. The structural performance was determined using a Geogauge, light weight deflectometer, and Benkelman beam deflectometer. The functional condition assessment comprised roughness and distress study using smartphone sensors after validation with a Roughometer III and a video processing technique. The skid resistance was evaluated using the British pendulum test. Further, a cost analysis was carried out to compare the construction cost for both pavement types. The test results revealed that both types of pavement displayed distinct performances for several structural and functional aspects. It was also concluded that the construction cost of the ICBP was less than the flexible pavement section. The present study aids in understanding the structural and functional performance level of ICBP over flexible pavement.
