Higher traffic intensities and pavement loadings re#uire more

dura$lepavements%

Higher traffic intensities also command longer maintenanceintervalsto increase availa$ility of the road%

&nvironmental pressure is increasing' reduction of use of naturalresources such as aggregate and less emissions are highly desired%

SBS modification has proven $enefits in wearing courses over thepastdecades in every relevant property%

(se the $enefits of SBS to create a polymer modified $ase courseasphalt that can fulfil the re#uirements of today and tomorrow%
