ECONOMIC ASPECTS OF CERAMIC WASTE RECYCLING THROUGH ITS USE AS AGGREGATE IN MINERAL-ASPHALT MIXTURES

Bartosz Zegardło, Wojciech Andrzejuk, Urszula Andrzejewicz, Jerzy Nitychoruk

Abstract


Subject and purpose of work: This article is a continuation of ongoing research; whose primary aim was to show ceramic waste as a full-value substrate for the production of mineral-asphalt mixtures. The authors, basing on the examined characteristics of aggregate obtained in the process of crushing the socalled “ceramic cullet”, present the thesis that this material can be a full-fledged aggregate for concretes used in road construction. The authors emphasize ecological advantages of such a solution. The purpose of this research was to analyse whether such measures as those described above are economically justifiable.
Materials and methods: In the article, based on business data, the costs were estimated and compared to the prices of the aggregates used by companies producing asphalt mixtures.
Results: Economic comparisons have shown that the costs of described recycling were not satisfactory.
Conclusions: Taking into account the ecological effect, it is recommended that ceramic waste is recycled by using it for the production of mineral-asphalt mixes for general use.
