Innovative approaches towards the use of locally available natural marginal materials

The utilization of materials locally available on the site of a road project is a major concern in the context of sustainable development and perfectly meets the socioeconomic and environmental criteria involved in it.

The report is based on the answers received from twenty-two countries. Five different families of locally available marginal natural materials have been identified. Information on placing and processing is given for each country. A comparison is also made of classifications and specifications and their application in the case of marginal materials.
