TRL was commissioned by National Highways to carry out a project to explore ways of achieving smoother pavements on the Strategic Road Network (SRN) through improved standards, which will lead to cost-effective changes in construction and maintenance practice. A suitable compliance approach for smoothness of new surfaces was developed that could be deployed using non-contact measurement methods. To test the appropriateness of the proposed compliance process and the associated thresholds, a trial was undertaken, and this report presents the details and outcomes of that trial.
