1. 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

2. 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

3. EFEITO DA RADIAÇÃO SOLAR NO ENVELHECIMENTO DO CONCRETO BETUMINOSO USINADO A QUENTE
The asphalt aging due to the action of the solar radiation can be considered in the study of the performance of asphalt pavement, especially in Brazil, where the sunstroke is very important. The aim of this work is to simulate and investigate the asphalt aging due to the solar radiation effect. The hot worked bituminous cement was submitted to the weather-O-
