Estudio de superficies urbanas multifuncionales de hormigón poroso

Abstract

Porous concrete pavements are considere done of the most complete Sustainable Urban Drainage Systems (SUDS). Its porous structure is suitable for road traffic and pedestrians, while allowing rainwater to infiltrate into the inner layers reaching the subsoil, or to be stored for later use, controlling surface runoff, decreasing water pollution. The present doctoral thesis has worked on the development of a new methodology of design that allows the increase of mechanical resistance while maintaining an adequate water infiltration. Different aggregates, gradations, additives and fibers, and compaction methods have been used, as well as alternative materials to cement (geopolymers), evaluated through various mechanical, hydraulic and superficial tests. Results have been discussed and compared through statistical and multi-criteria analysis tools to obtain the optimal dosages.
