RTI ramp Modified Jeep ramping an RTI ramp Ramp travel index or RTI, is a way of measuring a vehicle's ability to flex its suspension, a property also known as axle articulation. The RTI rating is used mainly in the off-roading industry to test and describe chassis limits of modified vehicles.
Example: If the height of a ramp is H = 1 meter and its length is L = 5 meters, then the mechanical advantage is = =, which means that a 20 lb force will lift a 100 lb load. The Liverpool Minard inclined plane has the dimensions 1804 meters by 37.50 meters, which provides a mechanical advantage of
Ultralow strength: characterized by K = 20 MN/m^3 and representing all K values below 25 MN/m^3 for rigid pavements, and by CBR = 3 and representing all CBR values below 4 for flexible pavements D: Maximum allowable tire pressure: Unlimited: no pressure limit W: High: limited to 1.75 MPa X: Medium: limited to 1.25 MPa Y: Low: limited to 0.50 MPa Z
β° = Breakover angle; C = Underside of chassis; W = Wheel; G = Ground; M = Midpoint of wheelbase Example of a vehicle at a significant breakover angle.. Breakover angle or rampover angle is the maximum possible supplementary angle (usually expressed in degrees) that a vehicle, with at least one forward wheel and one rear wheel, can drive over without the apex of that angle touching any point ...

Gravity escape ramp: a long, upwardly inclined path parallel to the road. Substantial length is required. Control can be difficult for the driver; problems include rollback after the vehicle stops. Sand pile escape ramp: a short length of loosely piled sand. Problems include sudden, forceful deceleration; sand being affected by weather ...
The DMRB is used to design trunk roads such as the A20 in the UK. The Design Manual for Roads and Bridges (DMRB) is a series of 15 volumes that provide standards, advice notes and other documents relating to the design, assessment and operation of trunk roads, including motorways in the United Kingdom, and, with some amendments, the Republic of Ireland.
