挪威公共道路管理局发起了一项促进在道路结构中使用回收材料的方案。通过回收废玻璃生产的粒状泡沫玻璃正在被研究作为道路建设应用的材料。生产过程涉及将来自不同玻璃源的精细研磨的玻璃粉末与活化剂（如碳化硅）混合。在研磨过程中，重金属被分离并回收到金属熔化厂。将粉末散布在钢带输送机上，该钢带输送机穿过高温烘箱，粉末在高温烘箱中膨胀以形成泡沫。当它离开烤箱时，它会裂成更小的碎片。该材料的特点是良好的排水和绝缘性能和重量轻。它可以用作轻质填充材料和/或防霜绝缘层。公共道路管理局进行的现场测试的监测方案的结果。介绍了在Eggemarka的E6公路上使用泡沫玻璃来减轻涵洞重量、提高稳定性和减少沉降问题。
The Norwegian Public Roads Administration has initiated a programme to promote the use of recycled material in road structures. Granulated foamed glass, produced by recirculating waste glass, is being investigated as a material for road construction applications. The production process involves mixing finely ground glass powder from different glass sources with an activator such as silica carbide. During grinding, heavy metals are separated and recycled to metal melting plants. The powder is spread on a steel belt conveyor running through high temperature ovens where the powder expands to form a foam. When it leaves the oven it cracks into smaller fragments. The material is characterised by favourable drainage and insulating properties and light weight. It can be used as a lightweight filling material and/or frost insulating layer. The results of a monitoring programme of field tests conducted by the Public Roads Administration are presented. Use of foamed glass on road E6 at Eggemarka to reduce the weight on a culvert, improve stability and reduce settlement problems is described.
