Occupational safety and environmental protection

Asphalt laying with occupational safety in mind

For decades, highway workers were portrayed shrouded in dust and heavy fumes. And while regulations for the quality and performance of asphalt laying have continously improved, paving crews and construction site personel are still exposed to vapors and aerosoles from bitumen. We believe it's paramount to work towards reducing these to the lowest possible minimum and comply with occupational safety regulations in asphalt road construction.

Safely comply with exposure limits

aspha-min® reduces the mixing and laying temperatures of asphalt mixtures which not only improves workability and compactability, but also significantly reduces vapors and aerosols from bitumen. Studies show that reducing the temperature of the asphalt mix by approximately 30 °C reduces the emission of vapors and aerosols from bitumen by about 75%. Consequently, construction site personel (as well as nearby residents and bypassers) are also exposed to fewer odors during laying.

As a result, warm mix asphalt with aspha-min® will play a crucial role in complying with new occupational safety regulations for bitumen vapors and aerosols. When used in combination with a vacuum-equipped laying machine, warm mix asphalt with aspha-min® will be a preferred method for not exceeding occupational exposure limits and with more than 30 years of experience with warm mix asphalt, we would be happy to advise you.

Product Informationen

About

aspha-min® is a mineral additive for the production of both warm mix asphalt (WMA) and hot mix asphalt (HMA). OIn warm mix asphalt, it reduces the mixing and/or laying temperature as well as emissions and enhances both compactability and workability. In hot mix asphalt (HMA), it leads to a reduction in viscosity and helps to handle challenging paving situations.

Effect

aspha-min® is a finely granulated additive for the use in asphalt mix. As a synthetic zeolite, it contains water of crystallization, which is gradually released when heated. The process creates micropores in the binder in order to temporarily increase its volume and reduce its viscosity for improved workability - even at lower temperatures.

Advantages

No risks or side effects: The use of aspha-min® allows for either warm mix asphalt with lower emissions or hot mix asphalt with enhanced compactability to be produced and paved without any changes to quality, durability and performance - without any additional risks or unwanted side effects.
