1. Viscoelastic Behaviour Characterization of a Gap-graded Asphalt Mixture with SBS Polymer Modified Bitumen
A characterization of the linear thermo-viscoelastic behaviour of a gap-graded bituminous mixture with SBS-polymer modified bitumen and RAP aggregates is presented in this paper. A comparison was made, in terms of their viscoelastic behaviour, between this innovative mixture and two commonly used well-graded base-course French mixtures made with pure bitumen

2. 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

3. Utilising neural networks and closed form solutions to determine static creep behaviour and optimal polypropylene amount in bituminous mixtures
The testing procedure in order to determine the precise mechanical testing results in Marshall design is very time consuming. Also, the physical properties of the asphalt samples are obtained by further calculations. Therefore if the researchers can obtain the stability and flow values of a standard mixture with the help of mechanical testing, the rest of th

4. Caracterização e uso de agregados lateríticos do Distrito Federal e do Estado de Roraima em CBUQ / Characterization and use of lateritic agregates from the Federal District and Roraima state (Brazil) in hot asphalt mixes
Esta tese apresenta o comportamento mecânico de quatro misturas betuminosas usinadas a quente fabricado com agregados lateríticos do Estado de Roraima e do Distrito Federal e CAP 50/70. Após lavagem e secagem ao ar, os agregados foram britados e enquadrados na faixa C do DNIT. Foi mantida a mesma granulometria para as quatro misturas, variando apenas o ti

5. Study of permeability of bituminous mixture of open course graduation / Estudo da permeabilidade de misturas asfalticas de graduação aberta
A malha rodoviária brasileira tem grande importância para o desenvolvimento do País. Observando-se que esta malha é predominantemente de pavimento flexível, o estudo das propriedades de misturas betuminosas se toma indispensável. Com o desenvolvimento tecnológico de asfaltos, novas aplicações estão se mostrando viáveis e tecnicamente interessantes

6. Avaliação do reaproveitamento de areia de fundição como agregado em misturas asfálticas densas / Evaluation of the reusing of waste foundry sand as an aggregate in dense asphalt
Foundry sand is an industrial solid waste resulting from sand casting process in foundry industries. Depending on the type of foundry process (green sand molding, shell sand molding, molding using synthetic resin and others) and of the type cast metal, this waste may contain elements and/or chemical compounds that may cause environmental impact. The substanc
