INSTRUCTOR: David K. Hein, P.Eng
Purpose and Background
This webinar outlines the history and use of waste and by-product materials used in the construction of pavements. This includes a wide range of products such as lignosulphates, cement and lime materials for the stabilization of subgrades, crushed glass, recycled concrete and asphalt, bailed tires, recycled plastics, shredded tires, construction demolition waste and lightweight aggregates for base and subbase and recycled concrete and asphalt, glass, steel and blast furnace slags, waste shingles, engine oil, asbestos and ground rubber for pavement surface materials. The potential benefits and dis-benefits of the use of each material are outlined.
