1. 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

2. Emissões de poluentes atmosféricos em condições reais de pavimentação asfáltica: material particulado, black carbon e hidrocarbonetos policíclicos aromáticos
Intensive use of asphalt generates pollutants into the atmosphere which are harmful to the environment and worrying for occupational health. The application of asphalt products leads to emissions of significant concentrations of polycyclic aromatic hydrocarbons (PAHs) and particulate matter (PM) to the atmosphere. This paper aims to assess the pollutant emis

3. Interfacial bond-slip relationship between Carbon Fiber Reinforced Polymer Plate and Concrete after High Temperature of Asphalt Paving Construction
Abstract The bond-slip relationship of Carbon Fiber Reinforced Polymer (CFRP) plate-concrete after the influence of high temperature action of Stone Mastic Asphalt (SMA) paving was investigated in this article. Two groups of double shear specimens with different bonding length were designed and tested. Based on the test results, the failure modes of specimen

4. Estudo da incorporação de resíduos da industria calçadista em misturas asfálticas
ABSTRACT The footwear industry discards residues in its most diverse phases of production, the Ethylene Vinyl Acetate (EVA) being one of them. This work proposes an evaluation of the use of EVA’s residue discarded by the footwear industry of Campina Grande city in asphalt mixtures. The modified asphalt binder was characterized by penetration test, softenin

5. 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

6. Estudo de misturas asfálticas mornas em revestimentos de pavimentos para redução de emissão de poluentes e de consumo energético. / Study of warm mixes asphalt as a pavement surface for reducing polluants emissions and energy consumption.
In the last years there has been an increasing concern for the environment. In this context, warm mixes asphalt was developed with positive impact not only on the environmental pollution, but also on the energy consumption, due to the reduction of mixing and compaction temperatures. This work compares the behavior of warm mixes asphalts (with surfactant addi

7. Uso de materais não convencionais para base de pavimentos asfálticos no muunicípio de Aparecida de Goiânia - GO / The use of non-conventional materials for asphalt pavements base in the city of Aparecida de Goiânia-GO
The city of Aparecida de Goiania-GO has a current estimate of 16,782,313 m of urban roads, and there are still 51.5% to be paved. However, the technical staff of the mayor is facing a challenge related to the purchase of lateritic gravel for paving of these streets. Taking into account that most roads in the city has a low volume of traffic (N ≤ 5.105)

8. 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

9. UtilizaÃÃo de Materiais Alternativos para a ConstruÃÃo de Pavimentos Urbanos na RegiÃo Metropolitana de Fortaleza / THE USE OF ALTERNATIVE MATERIALS FOR THE CONSTRUCTION OF URBAN PAVEMENTS ON FORTALEZA METROPOLITAN REGION
The shortage of natural raw materials in large urban centers encourages the study of alternative materials. With regard to the generation of waste from construction and demolition waste (CDW) the problem goes beyond the economic barriers and their irregular arrangement results in disturbances to the population in many different ways: proliferation of vectors

10. Comparison between the field performance of CAP 30-45 and CAP 50-70 for pavement layers. / Comparação do comportamento em campo de concretos asfálticos com CAP 30-45 e com CAP 50-70 para revestimentos de pavimentos.
In the last years, the volume of commercial heavy vehycles that transit through Brazilian highways is increasing. In addition, pavement wearing courses are exposed to the influence of high temperatures, that cause precocious asphalt layer distresses Therefore, asphalt mixture alternatives to the high traffic higwayshave been studied. One of the possibilities

12. Asfalto modificado com polimero SBS para pavimentos drenantes / Asphalt modified with polymer SBS for drain pavements
The polymer SBS - Styrene-Butadiene-Styrene has been very employed to modify the asphalt, for paving and for industrial applications. In that research the study of the asphalt was approached modified with polymer SBS, presenting better behavior than I asphalt conventional, being shown as the polymeric behaves when being mixed with the asphalt and which chara
