1. Utilização da cinza do bagaço da cana-de-açúcar como agregado miúdo em concretos para artefatos de infraestrutura urbana
Brazil is the main sugarcane world-producer and it is the leader in all segments (sugarcane, sugar and alcohol). The waste consisting of sugarcane bagasse is produced at the end of grinding process and it is used to generate energy through burning in boilers. At the end of burning, the ashes of bagasse are often thrown into environment improperly. In this co

2. Procedimentos de projeto e execução de pavimentos permeáveis visando retenção e amortecimento de picos de cheias. / Design and built procedures of porous pavements with porpose to retaining an reducing downstream floodings.
The present work intents to show design and built procedures, of porous pavements; by paying attention on its practical appliances as compensatory option in urban drainage with purpose to retaining rainfall water by storage, reducing downstream flooding in cities with great urban density. The procedures here proposed are based in the know how acquired for th

3. Influence of subsurface drainage in the service life of roadway pavements. / Considerações sobre a drenagem subsuperficial na vida útil dos pavimentos rodoviários.
There has been verified, in practice, that the absence of pavement drainage is one of the main factors of early degradation of pavements. More, there are few procedures of design and performance analysis that effectively consider the damage of water during the design period. However, foreign experiments and researches do not establish a reliable correlation

4. Considerations about highways shoulders design. / Considerações sobre o projeto de acostamentos para rodovias.
Shoulders has important functions in a highway, so much in relation to the improvement of the operational conditions, such as the capacity and the road safety, as for the pavements performance, protecting the structure of the mainline, improving the drainage and load transfer conditions. However, the shoulders have been suppressed or implanted in incorrect w

5. Indicators of potentialities and performance of recycled aggregates of construction and demolition wastes in flexible pavaments / Indicadores de potencialidades e desempenho de agregados reciclados de resíduos sólidos da construção civil em pavimentos flexíveis
The solid residues produced during construction and demolition are generally considered useless and cause several social and environmental impacts when not disposed appropriately. Solid residues are often deposited irregularly, result in obstruction of drainage systems, and cause the proliferation of vectors of diseases. Some experimental programs undertaken

6. Influence of drainage system efficiency in the asphalt pavement performance. / Influência da drenagem subsuperficial no desempenho de pavimentos asfálticos.
Since the implementation of the first roads, there are indications that constructors already had knowledge concerning drainage influence in the pavement performance. Many countries, where highway administration costs are criteriously available along pavement lifetime, have been developing researches regarding considerations about harmful effects from excessi
