1. 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)

2. Metodologia de previsão do comportamento mecânico de solos tratados com cal / Prevision methodology of mechanical behavior of soils treated with lime
Cada vez mais frequente a utilização de técnicas tradicionais da engenharia geotécnica depara-se com obstáculos de caráter econômico e ambiental. A técnica do solo-cal torna-se atrativa quando o melhoramento das propriedades do solo do local constitui-se numa alternativa de projeto. A técnica de tratamento de solos com cal encontra aplicação, por

3. 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

4. ESTUDO LABORATORIAL DE MISTURAS DE FOSFOGESSO, SOLO TROPICAL E CAL PARA FINS DE PAVIMENTAÇÃO / Laboratory study of mixtures of gypsum, lime and tropical soil for paviment
The phosphogypsum, subproduct of the manufacture of the phosphoric acid, became the objective of studies, due that it requires the availability of large areas to be stored. The disposal this waste increases the cost of generating company and can even cause a series of environmental problems. In this context, It has been arisen the interest to study the appli

6. Liming and aluminum forms in three places under no-tillage system. / Calagem e formas de alumínio em três localidades sob sistema de plantio direto.
Several agricultural areas under no-tillage system (NT) in Brazil present soils with low pH values and higher aluminum content. In spite of the apparently unfavorable condition to agriculture of such areas, high yields and lack of responses of crops to lime application have been observed, probably, because of aluminum chemistry in soils under no-tillage.

7. Distribuição e biodisponibilidade do níquel aplicado ao solo como NiCl2 e Biossólido. / Distribution and bioavailability of nickel applied to soil as nicl2 and biossólid.
The role of Nickel in soils under the application of biossolids is still not very well known. The objectives of this study were to investigate the influence of total Nickel and organic carbon content, and soil pH, in the Nickel distribution among soil fractions and the bioavailability of the metal to lettuce. Three incubation pot trials were carried out in g

8. Desempenho fisico-mecanico e propriedades termofisicas de tijolos e mini-paineis de terra crua tratada com aditivos quimicos
The aim of this research was the studying of the effect of chemical additives (lime, Portland cement and sodium silicate) on soil in order to obtain compressed soil bricks and prismatic mini panels constructed with such a material being their physical and mechanical characteristics determined in laboratory conditions and its behavior evaluated through the as
