In the end of May 2011, approximately 3500 metric tons of asphalt rubber mix
was placed on road E12 in northern Sweden with the aim to evaluate whether Asphalt
Rubber is a suitable approach to fulfill the need for long-life pavements with good flexibility
in this part of the country. Because of good experiences with dense graded, soft binder
asphalt mixes, a dense graded Asphalt Rubber mix with soft base binder was developed. This
product, along with a regular gap-graded Asphalt Rubber mix and a reference dense graded
asphalt mix was manufactured and paved during the project. The pavement looks visually
promising. Initial functional testing is completed with promising results, and additional
testing will be completed during spring 2012.
