The use of recycled glass for the construction of pavements

摘要

The construction of pavements is usually based on different national and international standards. The overall thickness of the pavement construction depends on many different parameters. Especially during construction of pavements across soft soils, large settlements occur which often results in damages to the pavement layers. Besides improvement of the soft subgrade material by different methods the vertical loads on the soft subgrade can be reduced by the use of light infill materials. One of those materials is called glass foam gravel and is produced from recycled glass. FilterPave™ can be used as an alternative for the asphalt and concrete layers. This material is also manufactured from recycled glass. The main advantage of this product compared to asphalt and concrete is its high permeability without any loss of bearing capacity. Both sustainable materials for the construction of pavements are described in the paper.
