Lusk et al. claim that American Association of State Highway and Transportation Officials (AASHTO) guidelines discourage " physically separated and bicycle-exclusive paths adjacent to sidewalks. " 1 In fact, these guidelines prohibit bicycle lanes on the roadway separated from travel lanes by parked cars or a raised barrier. They permit bike paths adjacent to the roadway where there is " minima...

Los conductores de camiones en pendientes descendentes pronunciadas pueden perder el control del vehículo por sobrecalentamiento sistema frenos. Ante esta posibilidad, las rampas escape para ayudan a detener esos vehículos errantes, reduciendo la fatalidad y daños materiales. La AASHTO presenta recomendaciones sin mostrar un procedimiento analítico justificar su necesidad o estimar ubicación. E...

A prospecção e análise preliminar de solos para identificar a sua tendência comportamento como subleito através da classificação AASHTO, gera custos iniciais altos aos projetos rodoviários, os quais, muitas vezes, oneram o seu valor final, tendo em vista que custo geotecnia rodoviários é estimado 30% na média, no âmbito do Ceará. Uma forma otimizar identificação material seria muito positiva ár...

The concept of rational pavement design for design of bituminous pavement was conceived during the 1960s (Dorman 1962, Monismith et al. 1961). Its upgraded version is known as Mechanistic-Empirical (M-E) pavement design, and is at present popularly being used for design of bituminous pavements in various countries. A number of pavement design guidelines (Austroads 2004, French 1997, IRC:37 2001...

Pavement design is the process of calculation thickness pavement layers which can withstand expected traffic load over life without deteriorating. In another word, it providing a structure in stresses on subgrade are reduced to acceptable magnitude. Highways Sudan deteriorate first years construction due many reasons including deficiency design. This research aims minimize probability roads fai...

The main objective of this work is to analyse the potential for potable water savings in university buildings by using stormwater collected from permeable pavements. Six located on campus Federal University Santa Catarina (UFSC) were selected obtain monthly consumption patterns and parking lot areas. same six then evaluated considering their location eight different cities Brazil, with rainfall...
