In densely populated areas, such as in the Netherlands, traffic noise is a major problem. To enlighten this problem, noise reducing thin surfacings were developed. These became popular in urban areas roughly 10 years ago for (provincial) highways. This type of pavement surface consists in most cases of thin (semi-)open asphalt mixtures (about 10 to 20% air voids).

With the use of a newly developed heavily polymer modified bitumen (PmB) a thin surfacing could potentially also be laid down at intersections, tight turns, interchanges and heavy duty roads. To do so, the pavement has to withstand severe shear forces under different environmental conditions during a comparable lifetime as a conventional Dutch SMA-NL5.
