2000 - USA - QA of Road Roughness Measurement


2000 - USA - QA of Road Roughness Measurement

This report describes a study designed to establish the accuracy and repeatability of high-speed, road-profiling equipment. This effort focused on a series of roughness validation sites. The study addresses selecting the appropriate sites, determining the “true” or reference profiles for these sites, implementing high-speed testing procedures, and developing a method for processing profiles and reducing the corresponding roughness indices.

The findings suggest that laser-equipped, high-speed inertial profilers, driven by skilled operators, are capable of providing exceptional levels of repeatability within an acceptable bias for a standard reference device (the Face Companies’ Dipstick®). The study further offers some preliminary repeatability and accuracy goals for equipment used to conduct construction acceptance testing (for smoothness) as well as for network roughness surveys.

Chris in the NCT Race 

Chris has an adventurous spirit which generally involves cycling, running, or just being out there having a good time. Read his 'Race Reports' below. This is a link to his SPOT GPS tracker. If you are interested in his 'geeky' sport technical blog it is at www.tri-duffer.com. He also has stories of his life as 'An Overtravelled Engineer Working for the World Bank' at World Bank Traveller.

Chris and Lis

We are Lis Pedersen and Chris Bennett. We’ve been married over 30 years and each found our way to New Zealand in the early 1980s from Denmark and Canada respectively. Golden Bay has been our happy place for almost 20 years and we are now based in Pohara just above the beach, with our two cats Coco and Max.
