ANALYSIS OF THE STRENGTH AND PERMEABILITY OF A PERMEABLE PAVEMENT DESIGNED WITH DIFFERENT PERCENTAGES OF RECYCLED CONCRETE

Abstract

The general objective of the research is to analyse the influence of using 10%, 15% and 20% recycled concrete (RCA) as a substitute for coarse aggregate on the compressive strength and permeability of a permeable pavement in urban projects in Cajamarca. This study was carried out due to the need to find sustainable and efficient alternatives that improve the properties of concrete, thus allowing the construction of more resistant pavements with adequate infiltration capacity, adapted to the current demands of sustainability and stormwater management. To achieve this objective, an experimental study was designed in which detailed laboratory tests were carried out on the aggregates, as well as the preparation of cylindrical specimens with different proportions of recycled concrete: 10%, 15% and 20%. These specimens, together with control (standard) samples, were subjected to compressive strength and permeability tests at 7, 14 and 28 days of curing. Statistical analysis of the data was performed using ANOVA tests, at a 5% significance level, to determine whether variations in the proportion of RCA significantly impacted the mechanical and permeability properties of the concrete.
