The recycling of worn tyres is enforced primarily by legal regulations, but it is also motivated by ecological and economic reasons. In Poland, recovery of rubber materials makes it possible to obtain materials of good quality and very broad applications, e.g. for plastic road surface or production of so-called rubber asphalt, used for the grindable layer of roads, as well as for innovative materials intended for filling bridge abutments of integrated bridges. The paper considers the financial aspect of using disintegrated rubber waste by analysing the cost of replacing the binder with different amounts of rubber dust (10%, 12%, 14%, 16%). With the assumptions made, the analysis allows for concluding that with an increase in the content of the rubber additive, the cost of the binder changes.
