Nano + RC material = optimal load-bearing layer
The accumulated recycling material is piling up into increasingly larger mounds, on one hand due to the sometimes lack of mechanical properties of the recycling material, and on the other hand due to the skepticism of designers, site managers, and clients. In particular, the reuse of milled asphalt is proving to be very difficult, as very strict requirements apply for its reuse.
For this reason, the company Nanoalps set itself the goal some time ago to develop a high-performance hydraulically bound foundation layer from recycling materials (especially milled asphalt). The tests investigated the enhancement of the mechanical properties of recycling materials by adding cement and nanopolymers.
As part of this research activity, foundation layers made from 100% recycling material were produced and tested. It was found that, compared to traditional load-bearing and frost protection layers, the newly developed foundation layers made from recycling material, in combination with cement and nanopolymers, achieved better mechanical performance values.
Milled asphalt can be added up to a bulk density of 70%. The remainder consists of regular recycled gravel.
This finding is especially important for the recycling of milled asphalt, as the stored quantities are growing larger and traditional recycling is very strictly regulated. This provides road builders with a cost-effective alternative, and milled asphalt can once again contribute to greater value creation.
