Abstract

The accumulation of solid wastes that add up to other types of wastes makes the environment more and more limited, with limited space due to its useful life. Given this fact, this research gives rise to the technical feasibility of using tire tube rubber associated with permeable concrete for use in urban paving. The goal is to develop a dosage from which this new material will come to commercial use both in the form of blocks, pavers, among other materials. The reference trait was used through the characterization of the materials and the dosage of 1:4 (cement:gravel 0) was determined, with a water/cement factor (a/c) of 0,32. The replacement of gravel by rubber chips was 50% making the dosage like this: 1:2:2:0.32. The average mechanical strength of the reference line was 27,2 MPa and the dosage with rubber chips was 25,5 MPa. Although the resistance has been limited to what was determined in the dosage (25 MPa), the feasibility of using this material meets the requirements of NBR 9781, and can be used in environments with light demand, such as sidewalks, squares and bike paths. Therefore, the previous analyzes of the water filtered by the specimen were positive regarding the pH, acidity and alkalinity characteristics and returned to the environment without contamination.
