1. 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

2. Uso de técnicas de low impact development no controle de impactos hidrológicos
RESUMO O crescimento desordenado traz diversas implicações na drenagem das bacias urbanas, principalmente no referente a alterações no escoamento pluvial. A bacia Mãe d’Água em Viamão (RS), no Brasil, retrata esse problema. Assim, levanta-se a seguinte questão: existem soluções de Low Impact Development (LID) compatíveis com a mitigação de imp

3. Análises de dosagens de concreto asfáltico do tipo Pré Misturado a Frio (PMF) utilizando Resíduos da Construção e Demolição de obras (RCD)
RESUMO Na construção civil, um problema ambiental recorrente é a geração e disposição de Resíduos de Construção e Demolição (RCD) de obras. A utilização do RCD como agregados na composição de concreto asfáltico, do tipo Pré Misturado a Frio (PMF), torna possível a execução de pavimentos rodoviários de baixo tráfego. Diante desses fatos

4. Effect of temperature gradients on the behaviour of jointed plain concrete pavements
Resumo Em muitos países da América Latina os pavimentos de concreto com juntas (JPCP) são calculados usando os métodos da “American Association of State Highway and Transportation Officials (AASHTO) ou da “Portland Cement Association” (PCA), os quais não levam em consideração explicitamente as condições climáticas específicas de cada região

5. Pervious concrete: study of dosage and polypropylene fibers addiction
Resumo Utilizar concreto permeável para minimizar os efeitos causados pela impermeabilidade do solo causado pela crescente urbanização é uma alternativa que ainda necessita de estudos quanto à sua concepção e aplicação. Seguindo esta linha, o presente artigo apresenta um estudo das características do concreto drenante, tal como a resistência à tr

6. Modelo de previsión de la progresión del área de fisuras en pavimentos asfálticos
This work presents the development of a model to predict cracking progression in hot-mix asphalt pavements, based on information obtained from a database maintained by State of Bahia Department of Transportation, with data collected in 2004. A factorial design was performed to arrange the data available in order to facilitate the statistical analysis. The fa

7. Contribuição para calibração de curva de evolução de afundamentos em trilha de roda de revestimentos asfálticos com utilização de resultados obtidos de simulador de tráfego em escala real. / A contribution to the calibration of performance curves for the prediction of permanent deformation in asphalt pavements using the results obtained from a large scale mobile traffic simulator
Permanent deformation, or rutting, is a critical type of pavement distress given that it is directly associated with transportation costs, due to a reduction of the ride quality, and user safety, due to poor driving conditions or water build-up during rainy periods that affect the tire-pavement interaction. In the case of pavements of highways belonging to c

8. Investigação de parâmetros do CCR com incorporação de escória granulada de alto forno para utilização como base de pavimentos. / Analysis of mechanical behavior of the RCC with incorporation of granulated blast furnace slag for use as pavement base.
The increasing environmental concerns as well as energy sources shortage leads industry to consider both optimization of production processes and sustainable use and disposal of its by-pass products. In siderurgical steel manufactures the most common by-pass product is the blast furnace slag with emphasis to its granulated shape. This study considered the ev

9. Procedimentos de projeto e execução de pavimentos permeáveis visando retenção e amortecimento de picos de cheias. / Design and built procedures of porous pavements with porpose to retaining an reducing downstream floodings.
The present work intents to show design and built procedures, of porous pavements; by paying attention on its practical appliances as compensatory option in urban drainage with purpose to retaining rainfall water by storage, reducing downstream flooding in cities with great urban density. The procedures here proposed are based in the know how acquired for th

10. Cálculo e detalhamento prático de pilares para edificações de pequeno e médio porte
Even the small buildinging column may have a buckled. Its denoted the difficulty to design and detail this type of element. So this work intends make a description and application of a several simplified process of presizing and columns design. The stability building procedures of the parameters a e γz are analyzed are applied to this kind of structure.

11. Mobile linear traffic simulator method to forecast behavior and performance of asphalt pavements. / Método de uso de simuladores de tráfego linear móvel de pista para a determinação de comportamento e previsão de desempenho de pavimentos asfálticos.
Full-scale accelerated pavement testing is defined as the controlled application of a wheel load in a pavement structure to determine the pavement system response and its performance under accelerated conditions of accumulated damage in a compressed time period (METCALF, 1996). Loads at or above the legal maximum allowed by highway agencies can be applied at

12. Influence of subsurface drainage in the service life of roadway pavements. / Considerações sobre a drenagem subsuperficial na vida útil dos pavimentos rodoviários.
There has been verified, in practice, that the absence of pavement drainage is one of the main factors of early degradation of pavements. More, there are few procedures of design and performance analysis that effectively consider the damage of water during the design period. However, foreign experiments and researches do not establish a reliable correlation
