3. Estimativa da eficiência do ensaio SPT através da execução da prova de carga estática sobre o amostrador / Estimation of the efficiency in SPT test through static load tests to the sampler
The Standard Penetration Test, SPT, is one of the most used one for subsoil information in the USA and Brazil. The data obtained in this dynamic test, such as the penetration resistance index, NSPT, the soil classification and phreatic level are used by different methods to estimate the shallow and deep foundations load capacity. For the same soil, the index

4. Mecanismos de penetração dinâmica em solos granulares / Dynamic penetration mechanisms in cohesionless soils
Ensaios de penetração dinâmica são ferramentas de investigação geotécnica de fácil execução e baixo custo. Estas características tornaram o ensaio SPT na técnica de investigação mais utilizada em diversos países como Canadá, Estados Unidos, Japão e principalmente, no Brasil. Em contrapartida, a penetração dinâmica de amostradores produz u

5. Reusing of fine quarries in paving: a technical and economical approach / Reaproveitamento de finos de pedreiras em pavimentação: uma abordagem técnica e econômica
The wastes generated by the quarry companies from civil construction represent an activity that has been outstanding because of the countless problems that appear with their stockpiling and maintenance. The great concern with those wastes is linked to the capacity to generate social and environmental effects that can harm the ambient through the appearance o

6. ESTUDO DA LIQUEFAÇÃO ESTÁTICA EM REJEITOS E APLICAÇÃO DE METODOLOGIA DE ANÁLISE DE ESTABILIDADE
Liquefaction is a phenomenon that happens in saturated granular soils when undergoing loadings rapid enough to produce great pore pressure increase with the consequent reduction of the effective stress and the shear strength. In the mining context, the possibility of the liquefaction occurrence in the granular tailings, when saturated, is a relevant concern

7. Estudo dos efeitos de escala em ensaios de penetração dinâmica / Study of scale effects in dynamic penetration tests
A engenharia geotécnica brasileira é fortemente dependente dos resultados do ensaio SPT, sendo de fundamental importância aprimorar os métodos de investigação e elaboração de projetos nesta área. Embora bastante utilizado, o ensaio tem sido objeto freqüente de críticas, abrangendo tanto aspectos relacionados à dispersão de resultados, quanto à

8. As abordagens sistêmica e do equilíbrio dinâmico na análise da fragilidade ambiental do litoral do Estado de São Paulo: contribuição à geomorfologia das planícies costeiras / Systemic approaches and the dynamic equilibrium in the analysis of environmental fragility of the coast of the state of S Paulo: contribution of geomorphology of coastal plains
The principal aim of this research, based on the Systems Approach and on the Dynamic Equilibrium, is to evaluate geological and geomorphologic different configurations and environmental fragility on the several geomorphologic topographic features in the coastal plains of Fortaleza bay in Ubatuba, located in the north coast of São Paulo and Peruíbe-Itanhaé

9. Aproveitamento de filer de pedreiras da região metropolitana de Goiânia em pavimentos flexíveis urbanos [manuscrito]: avaliação técnica e sócio-ambiental / Use of filer of quarries in the metropolitan area of Goiania flexible pavements in urban [manuscript]: assessment technical and socio-environmental / Use of filer of quarries in the metropolitan area of Goiania flexible pavements in urban [manuscript]: assessment technical and socio-environmental / Aproveitamento de filer de pedreiras da região metropolitana de Goiânia em pavimentos flexíveis urbanos [manuscrito]: avaliação técnica e sócio-ambiental
The generation of industrial waste has been the object of increasing attention in the field of Science and Technology because of the problems which arise when it is stored and inadequately disposed of. This can have negative consequences for the worker, the company and for the neighboring population. In addition it can generate liabilities for the environmen

12. Evaluation of asphalt mixtures produced with conventional peruvian asphalt binder PEN 60/70 and SBS polymer-modified type I 60/60 and PG 76-22 / Avaliação de misturas produzidas com ligantes asfálticos peruanos convencional PEN 60/70 e modificados por polímero SBS tipo I 60/60 e PG 76-22
The main goal of this work is the evaluation of the behavior of conventional peruvian asphalt binder AC PEN 60/70 and SBS polymer-modified asphalts I 60/60 and PG 76-22, when used in hot-mix asphalt (HMA), under both conditions with and without short-term aging. It aims also to establish the asphalt binder performance grade (PG), which is based on the weathe
