Comprehensive pavement evaluation using Benkelman Beam Deflection studies and Bump Integrator testing for structural assessment and road surface quality analysis.
Benkelman Beam Deflection studies are one of the non-destructive techniques for the structural evaluation of flexible pavements. A well-compacted pavement section or one which has been well-conditioned by traffic deforms elastically under each wheel load application such that when the load moves away, there is an elastic recovery or rebound deflection of the deformed pavement surface. This is the basic principle of the deflection method of pavement evaluation.
A bump integrator test is a method used to measure the roughness of a road surface. It involves using a specialized device called a bump integrator, which is attached to the back of a vehicle.
Structural assessment of flexible pavements using deflection measurements.
Road surface roughness assessment for ride quality evaluation.
Evaluation without damaging the existing pavement structure.
Data for pavement maintenance and rehabilitation planning.
The deflection method is based on the elastic behavior of well-compacted pavements under wheel loads. The measurement of rebound deflection provides valuable information about the structural condition and load-bearing capacity of the pavement system.
