How is ramp speed related to highway speed?
How is ramp speed related to highway speed?
The current relationship, in general, is for the ramp design speed to be 85 or 70 percent of the highway design speed, rounded up to the nearest 5 mph [10 km/h] increment, and limiting the speed differential to 10 mph [20 km/h] on the upper range and 20 mph [30 km/h] for the mid-range.
What to do when your front end is grinding?
Take the car to an auto shop to inspect and repair the power steering system. If the grinding noise occurs when the engine starts, then the flywheel may be damaged. This means that the teeth of the flywheel are worn out and are unable to mesh with the start drive gear. The flywheel should then be replaced.
What should the cross slope be on a ramp?
The cross slope for ramp tangent sections should be similar to the cross slope used on the main lanes of the roadway. The cross slope on the ramp should be sloped in the same direction across the entire ramp. The cross slope used will depend on the pavement used and other drainage considerations.
Why does my front end make a grinding noise?
