This project will develop high-performance, lightweight, concrete noise walls and acoustic barriers that use recycled tyre and glass products to improve sound absorption, and address environmental problems associated with the mining of river sands, and stockpiling of waste tyre and glass products. Innovation in noise wall technology consists in developing low-carbon concrete mixes (using less cement) with a maximum amount of recycled product, together with reducing wall thickness, while maintaining the necessary engineering properties such as acoustics, strength, and durability. In addition to higher acoustic insulation, the novel low-carbon, lightweight, panels will improve material handling and affordability of noise barriers.

该项目将开发高性能、轻质的混凝土隔音墙和隔音屏障，使用回收的轮胎和玻璃产品来改善吸声，并解决与开采河砂和储存废旧轮胎和玻璃产品有关的环境问题。隔音墙技术的创新在于开发低碳混凝土混合物（使用更少的水泥），最大限度地回收产品，同时减少壁厚，同时保持必要的工程性能，如声学、强度和耐久性。除了更高的隔音性能外，这种新型低碳、轻质的面板将改善材料处理和隔音屏障的可负担性。
