Design and performance of pavements incorporating residual materials for increased circularity

Purpose and goal:

The goal is to enhance the utilization of residual (circular) materials in road construction, aligning with the target of achieving climate-neutral infrastructure by 2040.

The objective of this project is to investigate several recycled and residual materials for their potential usage in pavement structures and to create the necessary design basis for this, particularly by updating the ME design tool ERAPave PP. Expected results and effects: The expected outcomes of this project are:

(1) identification of recycled and residual materials suitable for pavement structures (2) enhance the database of recycled material properties calibrated for field conditions (3) development of a design basis for using recycled materials for specific requirements road structures

(4) increase international cooperation related to utilization of recycled and residual materials in pavement structures. Approach and implementation: The project is divided into four working packages (WP): WP1 a Selection of circular materials b Testing of circular materials WP2 Structural design in a ME design scheme (ERAPave PP)

WP3 Validation the predicted performance and calibration of material properties WP4 Communication and dissemination
