New Material Solutions for Road Surface Construction Made of WMA

Abstract:

The need for modernization and adjustment of existing road infrastructure to European Union requirements will result in the need for processing thousands tones of waste. The amount of waste received from road repairs and road demolitions, as well as technological by-products in Poland may be estimated at the level over 2.5 million tones, which is almost 2% of all waste production. Construction waste recycling is truly justified in this case, together with waste management according to the provisions of national and international law. One of such products is dust generated as a side effect of stone processing in a Casey mine in Ireland. Laboratory tests of the new material compositions with the use of waste from this mine not only realize the general aims of economic and ecological assumptions, but also allow increasing quality of a new product which is an asphalt-concrete composite. In order to check the properties of the use of a filler in a form of Hornfels Ireland powder there was conducted a series of special tests on the asphalt concrete testing the wearing course. Hornfels Ireland powder produced as a waste material of an aggregate processing in Cassey Quarry is a useful material, which may be successfully used as a component in a process of WMA production.
