| Abstract | The acoustic quality of porous road surfaces can be optimized by defining an optimal texture and sound absorption for a given traffic mix. This is normally done in the design phase of a project. But how to ensure that the acoustic quality that is achieved production phase is similar to the designed quality? This can be checked with SPB or CPX measurements, but these might not be the most suitable conformity of production testing in all cases. The alternative is to specify acoustic quality by specifying civil engineering properties such as stone grading, layer thickness and porosity. We found that this might lead to wrong conclusions: surfaces within the civil engineering specs might underperform acoustically and surfaces outside the specs might be rejected while their acoustic quality is fine. We investigated an alternative approach where we specified the acoustic quality based on layer thickness and degree of compaction. With these parameters, the acoustic performance of a single road surface mixture design can be accurately predicted and controlled. This method is now used for the first time in the Netherlands. |
