color choice is restricted to red or green, however if available a clear asphalt cement expands the color choice to red, green, buff yellow and a natural finish. Duratint™ with conventional asphalt cement has excellent demarcation characteristics and good long term color retention properties, which make the material ideal for traffic calming schemes. Further examples of where an alternative color has proved beneficial are bus lanes and stopping areas and for highlighting cycle routes and lanes. The use of a synthetic, clear asphalt cement provides scope for a wider range of aesthetic alternatives typically used on private residential areas and commercial schemes where the use of a range of colors adds to the aesthetic value of the site.

Performance:

The addition of the red pigment to conventional hot mix asphalt designs does not impact the technical performance of the material.

The use of a synthetic clear asphalt cement will generally increase the materials resistance to fuel spillage, technical testing of materials using these binders have found comparable performance results to those achieved with conventional asphalt cement.

To maximize the long term color benefits the color should ideally be matched to that of the aggregate used in the mix (dependant on the level and type of traffic).
