Traffic noise − a burden to the majority of the population − engineers have made it their task to adress this point to contribute to a better quality of life.
One solution is the noise-reducing Stone Mastic Asphalt – SMA plus.
SMA plus perfectly combines potential for noise reduction, high stability and long service life. A special aggregate composition leads to a higher void content, which together with the optimized surface texture provides convincing, and above all, consistently good noise reducing results. SMA plus is suitable for all road classes. This technically and economically attractive approach arises from the combination of SMA plus, with an impermeable SMA binder course.
With these features, SMA plus fulfils all the requirements of a modern infrastructure − offering its benefits to road users, local authorities and the asphalt industry alike.
