Road surface profiling is an important part of highway and pavement management. Systems have been developed to collect real-time continuous highway-speed measurements of longitudinal profiles of road surfaces. From this data, engineers calculate International Roughness Index (IRI). These numbers are expressions for the roughness of a road surface.Surface roughness of a pavement has been recognized to be an important parameter for determining maintenance and rehabilitation needs for road networks.
Road profiling systems incorporate non-contact laser sensors to measure to the road surface and accelerometers to compensate for the effects of the vehicles movement. Profiling is mandatory for Road builders, contractors to gather statistical information on road surfaces.
ARRB are specialized in developing and manufacturing high quality pavement monitoring equipment such as road profiling systems for transverse profile, rut depth, macro texture and other shape characteristics.
