1. Tensile Behaviour and Durability Issues of Engineered Cementitious Composites with Rice Husk Ash
ABSTRACT The Engineered Cementitious Composites (ECC) is a special type of High Performance Fibre Reinforced Cementitious Composite (HPFRCC) characterized by a high tensile ductility with a 2% maximum volume of micro fibres. ECC has a tensile strain-hardening performance that leads to multiple cracking behaviour, thus providing the high ductility to the conc

2. 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

3. Behavior of nonwoven geotextiles impregnated with asphalt emulsion used in anti-reflective cracking systems / Comportamento de geotêxteis não tecidos impregnados com emulsão asfáltica usados como sistema anti-reflexão de trincas
The use of geosynthetics in roadway systems has received considerable attention over the past decades. Paving fabrics have been used for rehabilitation of pavements to reduce propagation of cracks and to extend pavement life. In addition, the success of this technique depends directly on the understanding of the geotextiles behavior when impregnated with asp

4. 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

5. Decision model for prioritization of urban roadways candidate to pavement maintenance and rehabilitation activities / Modelo de decisão para a priorização de vias candidatas às atividades de manutenção e reabilitação de pavimentos
The development of conservation programs, starting from the previous knowledge of pavements condition, makes possible to maintain certain quality levels in the roadway system. However, in a lack of budget scenario, to achieve those quality levels the decisions have to be taken considering a pavement maintenance and rehabilitation (M&R) prioritization program

6. A study of the influence of aggregate gradations in the cold micro surfacing performance in the lateral and vertical displacement / Um estudo da influencia da granulometria dos agregados no desempenho do microrrevestimento asfaltico a frio quanto ao deslocamento lateral e vertical
Revestimentos de cimento asfáltico de petróleo são utilizados como pavimentos de vias, as quais necessitam de manutenção preventiva e corretiva. Neste último contexto surgiu o microrrevestimento asfáltico a frio, que tem sido aplicado com sucesso como sistema corretivo de deficiências funcionais do pavimento. Como a mistura é composta por aproximada
