Purpose and goal

Polymer-modified bitumen (PMB) is a high-performance binder for asphalt pavements and it is often used for high-traffic roads and airport runways. This project aims to close the loop for PMB´s circularity by enabling high-value reuse of reclaimed asphalt (RA) containing PMB, i.e. its reuse back into PMB pavements.

Expected effects and result

This project will produce two main results: (1) a proposal for regulation that ensures the quality of PMB-RA; (2) a calculation method to determine the technical properties of binder for asphalt mixture when PMB-RA is used in PMB pavements. By disseminating the project results to a wide audience and interacting with other relevant projects, innovation effects and synergies will be created.

Planned approach and implementation

The project will investigate the specification and technical requirements for PMB-RA. A proposal for regulation will be developed to facilitate the reuse of PMB-RA back into PMB pavements. This project will also study the blending of old PMB in reclaimed asphalt and new PMB in order to develop a calculation method to determine the technical properties of binder for asphalt mixture when PMB-RA is used in PMB pavements.
