Warm mix applications

reducing the impact

In recent years, the Asphalt Industry has been diligently looking at ways to reduce the impact of road construction and maintenance on the environment. The development of reduced temperature asphalt or ”Warm Mix Asphalt” technology has been the cornerstone. Reduction of emissions during mix production and paving at lower temperatures not only reduces the carbon foot print of asphalt but also helps to reduce the amount of expensive fuel needed. In addition, it greatly reduces vapours and aerosols behind the paver which provide a much better working environment for the paving crew.

There are several ways to lower the impact of infrastructure on the environment. One way is to reduce emissions and fumes during production and paving by lowering the temperature of the mix. Major progress can also be made by building longer lasting roads using good quality materials, good construction practices and through the use of adhesion promoters to prevent premature moisture damage.

The use of recycled and locally sourced materials greatly reduces the energy required to transport large quantities of aggregate which also reduces the impact on the environment. AkzoNobel additives are designed to work with local materials that may be prone to stripping and there are additives specially designed to work with RAP (Reclaimed Asphalt Pavements).

Rediset® WMX and LQ warm mix additives provide certain unique benefits in addition to he general properties of lowering mixing and
compaction temperatures. Rediset® additives provide superior compaction and improved moisture resistance properties thereby resulting in longer lasting roads.
