Surfacing planning is a major activity for Highway Assets Management companies in term of material cost, work planning, traffic management and users safety. The highway surface wear-out is annually surveyed using SCRIM technology. A truck records 10 meters average measurements of surface roughness. Analyzing over-years-data changes and predicting future surfacing material needs is a major asset for cost optimization and maintenance-planning. However, comparing 10 meters linear-data over-years changes on the extend of the highway is challenging. The method I developed allowed to improve trust in data results, providing accurate surface roughness changes from 2008 to 2012.
