“…Despite these benefits, the potential for lower compressive strength, clogging, ravelling, and susceptibility to freezing and thawing damage, have limited the use of pervious pavements in cold climatic conditions [6]. When compared to conventional concrete, pervious concrete exhibits sustainability, because of its properties [7]. Some notable characteristics of pervious concrete are lower unit weight and drying shrinkage, higher permeability, higher thermal insulation, lower compressive, tensile and bond strength, lower pressure on framework during construction, and longer curing time required prior to form removal, elimination of capillary attraction, and economy in materials.…”

Various properties of pervious concrete, such as the compressive strength, split tensile strength, flexural strength, porosity and permeability, are studied in this paper for two aggregate gradations with different aggregate to cement ratios. Although the higher cement content exhibited better results for strength properties, the porosity and permeability results were lower. This study also aims to evaluate the balance between the porosity, permeability and compressive strength of pervious concrete for different aggregate size and cement content values. The test results show that it is possible to produce a pervious concrete mixture with acceptable permeability and strength values. Analiza svojstava procjednog betona U radu se analiziraju svojstva procjednog betona poput tlačne čvrstoće, vlačne čvrstoće cijepanjem, vlačne čvrstoće savijanjem, poroznosti i propusnosti, i to za dvije frakcije agregata i za različite udjele agregata i cementa. Iako se pokazalo da se s višim udjelom cementa postižu bolji rezultati u pogledu čvrstoće, na taj se način dobivaju niže vrijednosti poroznosti i propusnosti. Ocjenjuje se i odnos između poroznosti, propusnosti i tlačne čvrstoće procjednog betona za različite veličine agregata i različite udjele cementa. Rezultati ispitivanja pokazuju da se može postići mješavina procjednog betona koja ima prihvatljive vrijednosti propusnosti i čvrstoće.

“…Brazilian Portland cement CP IV-32 was used as water-activated binder, analyzed following the Brazilian standard NBR 5736:1999 [10]. Since there are no established methodologies to define the composition of pervious concrete, it was reviewed earlier works in the effort to identify the most common compositions used [14][15][16][17][18]. Based on these data, we developed mixtures containing different amounts of RCA (336, 350, 398, 485, and 539 kg/m 3 ) and coarse aggregate (1289, 1297, 1307, 1400, and 1628 kg/m 3 ) looking for the one with the best relationship between cohesion of fresh mixture and resistance.…”

ResumoThe expansion of urban areas under constant changes in the hydrological cycle directly affects the drainage of rainwater. The problems of urban drainage become major engineering problems to be solved in order to avoid negative consequences for local populations. Another urban problem is the excessive production of construction and demolition waste (CDW), in which , even with a increasingly policy of waste management , have been an end up being thrown in inappropriate disposal sites. Alternatively aiming to a minimization of the problems presented, we propose the study of permeable concrete using recycled concrete aggregate. In this study, there were evaluated the performance of concrete by means of permeability, consistency, strength, and interface conditions of the materials . Satisfactory relationships of resistance/permeability of concrete with recycled aggregate in relation to the concrete with natural aggregates was obtained, showing their best potential.Keywords: waste, pervious concrete, recycled concrete aggregates.A expansão de áreas urbanas força a uma constante alteração do ciclo hidrológico, que por sua vez afeta diretamente a drenagem das águas pluviais. Os problemas de drenagem urbana tornam-se grandes problemas de engenharia a serem resolvidos para evitar consequências nefastas para as populações locais. Outro problema urbano é a demasiada produção de resíduos de construção civil (RCC), pois apesar da criação de políticas para o gerenciamento destes resíduos ainda há grande quantidade de RCC sendo lançados em locais inadequados de disposição. Como uma alternativa de minimização dos problemas apresentados, propõem-se o estudo de concreto permeável com o uso de agregados reciclados de concreto como uma alternativa para pavimentação. Neste estudo foi avaliada a eficiência dos concretos por meio de ensaio de permeabilidade, consistência, resistência mecânica e as condições de interface. Obtiveram-se satisfatórias relações de resistência/permeabilidade dos concretos com agregado reciclado em relação aos concretos com agregados naturais, mostrando o seu grande potencial de uso.

“…In Putman and Neptune's study (2011), the samples consolidated with the proctor hammer were most similar to the actual pavements using the same mix design than the other compaction methods. When comparing cylinders to the pavement and slabs to the pavement, it was determined that the cylinders typically overestimated the pavement density while the slabs were more representative of reality (Putman and Neptune 2011). The cylinders were 0.5 ft in diameter and 1 ft in height and the slabs were 0.5 ft in thickness and either 1x1 ft, 1.5x1.5 ft, or 2x2 ft in length and width.…”

“…As the void content of a PC mixture increases, its density decreases accordingly, hence lower densities lead to lower strengths (Putman and Neptune 2011). A significant factor on the density of PC is the compaction method, the point of which is to eliminate large voids to strengthen the concrete without closing the voids needed for infiltration (Putman and Neptune 2011). Putman and Neptune explored different compaction methods in their 2011 study on the three methods of rodding, proctor hammer, and dropping (Putman and Neptune 2011).…”

AcknowledgementsThis work would not have been possible without the funding and research facilities of the Virginia Department of Transportation (VDOT) and its research branch, the Virginia Transportation Research Council (VTRC). The opportunities for implementation provided by VDOT are greatly appreciated.I would like to thank the following individuals for their contributions to the success of this research:  Dr. Celik Ozyildirim (thesis co-advisor), whose indomitable enthusiasm for concrete technology guided this project to speedy success.  Dr. Teresa Culver (thesis co-advisor), for her invaluable input with regards to stormwater management. iii AbstractStormwater runoff is a major concern as more land is developed into urban settings, morphing areas previously capable of infiltrating a large amount of water into impervious surfaces on which contaminants are collected and large volumes of runoff flow. Many effective practices for managing stormwater runoff exist currently with each method dependent on the surrounding development and the demands of that specific application. One treatment method available now is pervious concrete (PC), a type of permeable pavement that allows runoff to infiltrate, thus capturing contaminants before they reach the groundwater and slowing the runoff to alleviate flooding. Virginia Department of Transportation (VDOT) currently has no applications of pervious concrete. The purpose of this study was to conduct a literature review, field observations, and laboratory work to formulate a special provision by which VDOT could implement the technology of pervious concrete as a stormwater management tool. The results of the literature review, field observations, and laboratory work are presented in addition to the special provision formulated specifically for VDOT. From the work conducted in this study, it is evident that PC is a candidate for stormwater management that could perform satisfactorily in the Virginia climate and could be constructed with locally available materials.
