Dense Asphaltic Concrete can be an extremely versatile product, suitable for many types of applications. The ancient civilizations of Egypt, Babylon and Assyria all used bituminous lining materials and mortars for waterproofing and building, some more than 5,000 years ago, and many examples of their work remains intact even today. More recently with the advances in hydraulic [...]

Does Carbonate Aggregate Really Do Any Harm in Landfill Leachate Drainage Stone?

In the design of municipal landfill leachate collection systems, some state regulatory agencies require carbonate content of leachate collection system aggregate not to exceed 15 percent by weight. This requirement comes from a legitimate concern about the possibility of aggregate degradation, or loss of mass due to contact with leachate. Most involved in landfill design [...]
