Composite camber is a type of road surface design that combines a parabolic crown in the center with straight slopes towards the edges. This design utilizes varying slopes to optimize drainage and driving comfort.
Here's a breakdown of the key characteristics:
-
Parabolic Central Section: The central portion of the road utilizes a parabolic shape. This provides a gradual slope change, offering a smoother transition for vehicles.
-
Straight Sloped Edges: The outer edges of the road have straight, consistent slopes. This facilitates efficient water runoff and provides a definite edge for drivers.
-
Variable Slopes: Composite camber utilizes different slopes for the parabolic and straight sections, maximizing the benefits of both designs. The parabolic section's gentle slope provides comfort, while the steeper straight sections ensure quick drainage.
Why Use Composite Camber?
- Improved Drainage: Combining a parabolic crown with straight slopes facilitates effective water runoff, minimizing the risk of hydroplaning.
- Enhanced Driver Comfort: The parabolic central section provides a more comfortable driving experience compared to a consistently straight slope.
- Increased Tire Contact Area: By varying the camber, the tire contact area increases, reducing the pressure exerted by the tire on the road surface, thus minimizing wear.
- Safety: Better drainage translates to safer driving conditions, especially during rainfall.
In summary, composite camber is a road design that cleverly combines the benefits of parabolic and straight slopes to achieve optimal drainage, comfort, and safety.
