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. Load equivalency factors for off-road trucks
Abstract This article addresses an analysis of the Load Equivalency Factor (LEF) for off-road trucks. A new LEF curve for single axles with dual wheels covering trucks from 6.0 to 151.42 tons per axle is proposed, converting various magnitudes of damage from wheel loads to damage caused by the standard axle load of 8.2 tons. Then, this damage ratio was raise

3. Shear Strength of a typical soil from Manaus, Brazil, stabilized with ceramic residue additive
ABSTRACT The purpose of this study is to determine the geotechnical behavior of a clayey surface soil typical to the Manaus region (Amazonas, Brazil), when mixed with ceramic powder from brick residue produced by potteries located in the county of Iranduba, Amazonas, Brazil, and with residual sand (the reference mixture), commonly used in pavements in the re

4. Soil Stabilization with Lime for the Construction of Forest Roads
ABSTRACT The mechanical performance of soil stabilization using lime to improve forest roads was assessed. This study was conducted with lateritic soil (LVAd30) using lime content of 2% in the municipality of Niquelândia, Goiás state, Brazil. Geotechnical tests of soil characterization, compaction, and mechanical strength were performed applying different

5. UTILIZAÇÃO DO AGREGADO SIDERÚRGICO (ESCÓRIA DE ACIARIA) EM REVESTIMENTO ASFÁLTICO TIPO TRATAMENTO SUPERFICIAL / UTILIZAÇÃO DO AGREGADO SIDERÚRGICO (ESCÓRIA DE ACIARIA) EM REVESTIMENTO ASFÁLTICO TIPO TRATAMENTO SUPERFICIAL
Environmental sustainability requires preventive or mitigating environmental impacts caused by industrial production activities, to preserve non-renewable mineral resources. In this sense, this work is to evaluate through experimental studies predominantly by laboratory testing and field application the use of steel slag produced by Arcelor Mittal Tubarão i

6. Respostas estruturais em pavimentos flexíveis via utilização de equações de módulos de resiliência de solos de subleito e da camada de reforço / Structural responses in flexible pavements using equations of modules resilience of soil subgrade and the reinforcement layer
Este trabalho teve por objetivo analisar o comportamento resiliente de três solos típicos da região de Viçosa-MG, quando supostamente empregados no subleito e na camada de reforço de um pavimento flexível hipotético. Para cumprir esta finalidade, foram realizados os seguintes ensaios: caracterização geotécnica, compactação, empregando-se as energ

7. Study for use the wastes of the paper manufacture in the road construction / Estudo para a utilização de resíduo da fabricação de papel na construção rodoviária
The paper and pulp industry represent one of the most expressive industrial sector around the world, being of great importance to the world economy. In South America, because of the wide forest resources, Brazil and Chile are the largest pulp-producing. Brazil produces around 6 million tons of pulp per year, among which 98% of the pulp are produced by the bl

8. Reciclagem total de pavimentos de concreto como agregados para construção de novos pavimentos de concreto: o caso do Rodoanel Metropolitano Mário Covas. / Concrete pavement recycling for use as aggregates in new concrete for pavements - Mario Covas Metropolitan Road Ring case.
O estudo da reciclagem de pavimentos de concreto para utilização em novos pavimentos tem se mostrado de grande importância haja vista a quantidade de materiais necessários para a reconstrução dessas vias. Além do ganho ambiental, devido a uma menor extração de agregados, obtém-se um ganho econômico, com menor custo de transporte e de aquisição d

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. Study foliated quartzite waste to be the used in structures pavements. / Estudo do resíduo de quartzito foliado para emprego em estruturas de pavimentos.
The purpose of this study is to present an alternative use for quartzite mining wastes as base or subbase materials of flexible pavements. This proposition may not only reduces environmental impacts of quartzite extraction, but also valorises the quartzite aggregates, mainly for road applications. In Brazil quartzite extraction process produces about 90% of

11. Estudo do comportamento mecânico de um agregado reciclado de concreto para utilização na construção rodoviária / Study of the mechanical behavior of a recycled concrete aggregate for use in the road construction
Os resíduos de construção e demolição (RCD) representam cerca da metade dos resíduos sólidos urbanos. No Brasil, sua geração anual corresponde a aproximadamente 68 milhões de toneladas. Uma forma de se mitigar os impactos ambientais oriundos da disposição desses resíduos sobre o meio ambiente é o seu beneficiamento na forma de agregados recicla

12. 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
