Road Construction - an overview | ScienceDirect Topics

The basic unit of a road is a traffic lane, nominally designed to carry traffic in a single direction of travel. The minimal road configuration is generally two lanes, with one lane for each direction of traffic. Roads are then dimensioned in multiples of two: four-lane road, six-lane road, etc. Roads for long-distance travel with limited interruptions and access are generally referred to as “highways” or “expressways” in …

Screening Considerations – A Guide to Selection

Screen channels should be designed for approach velocities between 2fps (0.6m/s) and 3.3fps (1m/s). If velocities drop below 2fps, grit and screenings might accumulated upstream of the screen. Accumulated debris might lead to functional problems once a peak flow flushes that debris to the screens within a short time period. If velocities are higher than 3.3 fps (depending on the screen type) debris might bypass the
