Health & safety with Warm Mix Asphalt

24. October 2018

Road workers, cloaked in fume are a cliché of the past. Health and safety regulations for road works have become ever more stringent. Nevertheless, the exposure of workers to vapours, aerosols and odour cannot be denied. For occupational health and safety reasons, it should be our common goal to further reduce this burden. Consequently, asphalt temperatures should be kept as low as possible during production and laying.

Measurements conducted during field trials have shown that for the use of aspha-min® in Warm Mix Asphalt (WMA) and the reduction of mixing and laying temperatures, emissions of vapours, aerosols and odour are significantly reduced. For instance, the decrease of the mixing temperature by 26 °C leads to a reduction of 74% in emissions of ultra-fine particles. Of course, this goes along with substantially less odour - a situation of considerably lower exposure for workers at both the mixing plant and the construction site.

Today in Germany, with asphalt works in tunneling projects, means of reducing emissions are mandatory and Warm Mix Asphalt (WMA) has become a standard.. For this purpose, aspha-min® has particularly excelled in recent years.

Side effects? None. We prefer to keep pen grade and ring-and-ball at the given rate to maintain full reusability as RAP.
