BECERRA-ROJAS, José Santos. Use of construction and demolition waste for the production of paving stones for pedestrian walkways. Dyna rev.fac.nac.minas [online]. 2023, vol.90, n.229, pp.121-128.  Epub 03-Abr-2024. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v90n229.109178.

The main problem of our cities is the lack of treatment and final disposal of construction and demolition waste (CDW), which, accompanied by a lack of knowledge, becomes a major problem. Likewise, a city in the north of Peru (Cutervo) is not immune to the problematic reality experienced in the country and worldwide, since the lack of CDW management projects has generated the formation of informal dumps. The main objective of this research is to determine the technical and economic feasibility of using CDW for the production of pedestrian pavers, given that it includes measurements of the physical and mechanical characteristics to be analyzed. It is concluded that the use of CDW in the production of paving stones is feasible, from the economic and technical aspects, incurring a reduction in cost.
