Use of Industrial Wastes in the Construction of Low-Volume Roads

Lahtinen, Pentti O. / Jyrävä, Harri / Suni, Heikki

Many types of industrial waste can be effectively used in soil construction applications instead of depositing them into landfills. Everywhere in the world road construction offers best possibilities for applications because of the need for high volumes of material. This has been noted by Viatek Ltd / SGT during its long-term research and development work on soil construction applications based on industrial wastes. Industrial waste can be used as structural material for different types of road courses or as stabilizers of old structures that need to be renovated. There are many possibilities; for example as base courses or for frost insulating, weight reduction, drainage or sealing purposes. Most types of industrial waste are quite versatile and can be used to simultaneously solve different types of problems. One of the typical applications is the frost insulating and weight reducing base course. Many properties of the new structures based on industrial waste justify their use instead of conventional structures based on natural stone materials. Usually, the justification is most evident because of the technical and cost advantages from the fact that the new structures can be made thinner and with less material than the conventional ones. This is specially useful regarding the low-volume roads. Also, recycling of industrial waste in soil construction will promote the principles of sustainable development when saving non-renewable natural resources and reducing the volume of waste deposited in landfills.
