This paper is concerned with an attempt to find a solution for two problems of great importance in our daily lives.
On one hand, there is a continuous and rapid growth in the creation of wastes all over the world, a part of which is glass waste.
On the other hand, the development accompanying us in all fields requires the accelerated development of all types of infrastructure. One of the most significant components of infrastructure development is the increased pace of paving works for roads and runways that consumes dwindling quarry resources.
This work describes research that investigated the compatibility of crushed glass wastes (cullet) as a substitute for mineral aggregates in asphalt mixtures, thereby finding a solution for the increasing stockpiles of glass waste while conserving quarry resources.
The tests performed in this investigation have proven that cullet can be integrated into and form a part of the aggregates in asphaltic mixtures at a rate of 5%-15% without compromising the quality of such mixtures and their compliance with the requirements of standards and specifications or the potential for their application.
Two series of tests were performed: one in which glass smaller than 15 mm was used, and the second in which glass smaller than 6 mm was used.
In both cases it was found that there is no significant difference between the glass mixtures and conventional mixtures from the standpoint of test results and applicability. This solution, if adopted, will provide a solution for glass waste, significantly contribute to improving environmental quality and bring about an economic benefit to all interested parties.
