Selecting and specifying the correct linear drainage system for the project application under design should not be based solely on load rating. Other important factors should also be considered regarding the location and application area of the system. It can have an influence on how the channel will be treated when in situ. This includes:
Presence and level of dynamic forces
Intensity and speed of traffic
Traffic pattern (braking, turning, accelerating, crossing at tangents etc)
Location of structures (e.g. kerb-lines, building facades, landscape features etc)
Other factors that leave the channel protected or exposed at the surface
