This symposium

Towards a greener road infrastructure by integrating environmental aspects in procurement and design

Tools to calculate the total impact of

a material

a process

a combination of materials, processes

.

.. From cradle to … grave … and beyond?

3

Life cycle of Asphalt

Recycling Technologies

Saving our resources and environment for future by new technologies such as an effective recycling process

4

On going

How to optimize?

5

New technologies -for materials and energy reduction: higher recycling rates, better performances -for processes and management

ROAD_IT project

Objectives: • The development and implementation of a robust IT

architecture with digital portal that accomplishes communication between all relevant existing (and expandable to future) data input and output points for the production and paving processes in asphalt road construction.

• Interfaces and protocols are developed which are used as communication and standardization tools between the various heterogeneous sensors and data points, each with their specific properties (firmware, interface, measurement units, accuracy, ...).

• Through 4 documented proofs or concepts from the asphalt sector (Use Cases), elaborated and implemented in this project, the operation of the IT architecture and the portal is demonstrated.

• Knowledge flow to the sector.

Also process management and long term policy will become more important

Smart Selection Model for innovative Application of Reclaimed Asphalt Granulate in Road Design Material and structure design - Performance of asphalt containing RA: fatigue, healing, rutting - Using rejuvenators - Performance on site: Fatigue behavior after e.g. 5 years when RA is used?

On going How to optimize?

Is it really worth it?

And how to measure?

Why this symposium? To have a broad discussion and information exchange between researchers, industry and government about the challenges encountered in using Life Cycle Assessment and other tools to calculate environmental impact of products and processes in road constructions.
