1. Study of soils used with subgrade and sub-ballast in Brazilian railways
Abstract Brazil has an extremely limited railroad network compared to other developed and developing countries. There are projects to expand this mesh. Knowing that the cost of implementing a railroad is high, research for solutions that allow cost reduction is of great importance. But the parameters of the materials used in the subgrade and sub-ballast laye

2. Environmental effects of leachate extracts from reclaimed asphalt pavement: determination of metals, polycyclic aromatic hydrocarbon and acute toxicity to Daphnia magna
RESUMO Reclaimed Asphalt Pavement (RAP) has a variety of organic and inorganic compounds that can interact with the environment and promote deleterious effects on human health. This study investigated the potential toxicity of RAP through metal determination, polycyclic aromatic hydrocarbon (PAH) analysis and acute toxicity tests with Daphnia magna. Leached

3. Granulometric stabilization of laterites from Triângulo Mineiro and Alto Paranaíba for use in base course
Abstract The present article presents the study of three laterites from the Triãngulo Mineiro and Alto Paranaíba region, aiming to use it as a pavement base. The methodology used consisted of carrying out the tests prescribed by the DNIT 098/2007 standard and, as a complementary methodology, linear contraction, MCT classification, modulus of resilience and

4. Utilization of ferronickel slag in hot mix asphalt
Abstract The growing concern in minimizing the disorderly disposal of waste in nature has been influencing measures that seek to give new environmentally sustainable and economically viable purposes for these materials. The use of steel slag aggregate in road paving emerges as an alternative for reducing the storage of this material in industrial yards, as w

5. Flexible pavement overlay design of UFJF ring road based on the new Brazilian mechanistic-empirical pavement design method
Abstract The procedures for design and reinforcement projects regarding flexible pavements available in Brazil are mostly based on empirical models developed from studies carried out in specific localities, and therefore, should only be used in cases where equivalent climatic and traffic conditions are observed. The national highway agencies in partnership w

6. Um método de ensaio para determinação da concentração de óleo em amostras de águas contaminadas com óleos e graxas
RESUMO A concentração de óleos e graxas em amostras de águas contaminadas com resíduos oleosos pode ser determinada pelos procedimentos estabelecidos no Standard Methods for the Examination of Water and Wastewater. No entanto, sua aplicação nem sempre resulta em valores adequados ou níveis de precisão satisfatórios para atendimento de padrões norm

7. Evaluation of the self-cemeting effect of Construction and Demotion Waste (CDW) on mechanical performance over time for pavement support layers purpose
Resumo O problema relacionado a geração de resíduos de construção civil (CDW) está diretamente associado à sua elevada geração e disposição irregular, sobretudo quando tais resíduos são dispostos em aterros sanitários. Desta forma, torna-se cada vez mais importante o incentivo do reaproveitamento deste material, sobretudo em obras de grande con

8. Development of Epoxy Matrix Artificial Stone Incorporated with Sintering Residue from Steelmaking Industry
The present work is part of an innovation research project aiming to develop artificial stone from industrial wastes. In principle, the project goal is to fabricate artificial stones with improved characteristics to be used as plates for housing and road construction. In this work, the specific industrial residue was an electrostatically precipitated powder

9. Estimation of fatigue lives of fly ash modified dense bituminous mixtures based on artificial neural networks
This study deals with estimation of fatigue lives of bituminous mixtures using artificial neural networks. Different types of fly ash were used as filler replacing agents in a dense bituminous mixture. Fatigue tests were performed using repeated load indirect tensile test apparatus under controlled stress conditions. For determination of fatigue life, the in

10. Utilização da cinza do bagaço da cana-de-açúcar como agregado miúdo em concretos para artefatos de infraestrutura urbana
Brazil is the main sugarcane world-producer and it is the leader in all segments (sugarcane, sugar and alcohol). The waste consisting of sugarcane bagasse is produced at the end of grinding process and it is used to generate energy through burning in boilers. At the end of burning, the ashes of bagasse are often thrown into environment improperly. In this co

11. Avaliação do desempenho de pavimentos permeáveis / Experimental analysis of permeable pavements
This study aimed to evaluate the experimental performance of three types of permeable pavements constructed in three different structural conditions in order to control runoff in urbanized areas of the city of Goiania, Goias, adapting to the legal requirements and using local manufactured materials. It was evaluated nine experimental plots of 3.2 m as the fo

12. Caracterização de rejeitos de minério de ferro para uso em pavimentação / Characterization of iron ore tailings for use in paving
In this work it was carried out a series of laboratory tests towards chemical, mineralogical and geotechnical characterization of rejects from iron ore processing, for use in paving. Material sampling was done in specific points as they were generated during the beneficiation process along the cycle, in order to preserve their properties. The alternative app
