Another successful project on 1-39 in Beloit, WI laying a rubberized asphalt surface with the dry process asphalt application method with chemically engineered crumb rubber.

Barrington, Illinois-based Asphalt Plus, LLC pre­pared and supplied the Asphalt+ rubberized asphalt project which was put down during night paving with an outside temperature of 41 degrees.dry process asphalt

To prepare the Asphalt+ product, engineered crumb rubber (ECR) is precision injected into the asphalt plant drum through the RAP col­lar. A loss-in-weight system tracks the feed of rubber and calibrates the rubber-in-feed rate to the binder pump keeping the proportions of binder and rubber constant.

The finished Asphalt+ rubberized dry process asphalt moves through the plant just like regular hot or warm mix asphalt and the finished asphalt is transported and placed just like regular hot or warm mix asphalt.

The placement effort for the 1-39 rubberized asphalt paving was a success according to highway engineers working on the project.

In addition, no special binder holding/ mixing tanks or finished product silos were required and, because crumb rub­ber and other Asphalt+ materials were delivered directly to the plant site, there was no need for on-site mixing of solids and binder before use.

The I-39 S project gave the plant the ability to produce modified asphalt at significantly lower cost of modification. Dry mix rubberized asphalt saves $2-5 per ton and benefits the contractor/ producer as well as the state by delivering lower road life-cycle costs while giving communities safer and quieter roads.
