Abu Dhabi vision has greener and cheaper roads in the fast lane

Building new roads with recycled asphalt and concrete from demolished buildings will make inroads into the emirate's environmental footprint, the municipality believes.

ABU DHABI // New roads built with recycled asphalt and concrete will improve the emirate's environmental footprint, the municipality believes.

Guidelines set out by Abu Dhabi's Green Roads manual, to be published by the end of next year, aim to reduce carbon dioxide emissions involved in road construction by up to 30 per cent, while also cutting costs.

The manual will promote a classification system that would cover the entire lifespan of a construction project, from the planning, design and construction phases through to maintenance and operation.

One technique the manual promotes is recycling asphalt and other building materials, such as the concrete from demolished buildings.

The municipality has conducted several studies into the use of such materials, including a project in Shahama last year that cut the costs of pavement construction by 25 per cent.

The municipality has implemented a similar project in Bani Yas, where it is testing other techniques, such as reducing the thickness of pavements.

A municipality official said similar manuals from other countries, including the United Kingdom, United States and Australia, were being studied.
