SuPerPave® Mix Design Method of Recycled Asphalt Concrete Applied in the European Standards Context

نویسندگان

چکیده

The recycling of road and airport asphalt pavements requires greater reliability mix design in order to ensure proper rehabilitation effective reuse recycled concrete. Currently, internationally, the most procedures for concrete with RAP (Reclaimed Asphalt Pavement) refer guidelines developed by SuPerPave® Mixtures Expert Task Group. In this paper, according requirements European standard EN 13108, authors investigated above procedure. particular, were applied dosing components wearing course layer mixture determination PG (Performance Grade) critical temperatures binder contained (RAP binder) added ex-novo (virgin binder). experimental research program started from RAM Aggregate Material) grading characterization content determination. Afterwards, rheological selected virgin was carried out using DSR (Dynamic Shear Rheometer) BBR (Bending Beam devices. This step allowed us identify right percentages be binder. Then, compliance standards, study mixtures out, identifying necessary granulometric integrations virgin-binder-appropriate added. phase, three different used: 30%, 40%, 50%. Finally, plan completed a preliminary mechanical studied mixtures. results showed that implemented rational guarantees performance levels are fully standards.

Use of Recycled and Waste Fibers in Asphalt Concrete

A significant problem associated with asphalt concrete mixtures is the lack of durability resulting from an inadequate asphalt cement content. Additional asphalt cement added to increase durability results in flushing, bleeding and a significant loss In stability. Fibers have been used in stone matrix asphalt and open-graded friction course pavements successfully throughout Europe to allow high...
