Abstract:

The methods, indicators and their characteristics of the current pavement roughness evaluation are analyzed as well as their applications. Combining with the 1/4 car model, the evaluating progress of the current pavement evaluation method and indices are derived, their characteristics are summarized and the future developing trend is anticipated. The principles, technical standards, characteristics and conversion between different indices of the current method in pavement roughness evaluation are studied including the three meter ruler method, level instrument method, continuous road roughness meter method, recursive section instrument, laser profilemeter method and bump integrator method. It is pointed out that two shortcomings of IRI(international roughness index), in coordination of the roughness scope with plane scale and incapability of measuring the coupling effect are produced by road surface under all wheels. It is proposed to study the airliner-scale-adapted pavement roughness evaluation system with the airliner scale by the establishment of a full scale aircraft model.

Key words: pavement road engineering, evenness, literature review, 1/4 car model, full scale aircraft model
