The growing demand of society requires that engineers should concentrate more and more on recycling of broken road materials and various by-products in order to ensure environmental sustainability for future generations. Concrete technology has evolved to such an extent that it has become an important role in waste/secondary material management by now. There are several benefits of using glass waste in concrete mixtures. The experi-ments carried out at the Hungarian firm Ferrobeton Ltd. concentrated on exploring the possibility of using glass waste in the cement concrete recipe of vehicle restraint systems in order to release reflection in its material and thereby to increase road safety. In the concrete recipe, the maximization of both usability and reflectivity were aimed to. However, it was also necessary to make sure that the resistance to mechanical and environmental loads could not be worse than in the case of reference (basic) mixture recipe. The quality and type of concrete surface finishing is a financial and also lifetime design issue. The surface treatment method actually applied basically influence the light properties (gleam, reflectivity) of concrete surface as a significant traffic safety parameter.
