A ramp suitable to overcome the 1.8m drop in level is illustrated on the accompanying diagram.

image description

The important features are:

Ramp Geometry A gradient of 1 : 10 for the ramp should be suitable for most large vehicles. Powerful vehicles can manage 1 : 8 or even 1 : 6 slopes but for general and safe use 1 : 10 is recommended (i.e. 18m long for 1.8m height). Ramp side slopes of 1 : 2 are recommended to ensure stability of the sides and resistance to erosion.

Ramp Composition Granular fill (sandy, stony or rocky material) should be used and should be compacted while being built up to height. Clayey material should be avoided as it cannot be compacted properly and becomes soft when wet. The side slopes can be protected from erosion due to heavy rain by covering with coarser stones and rocks.

Hope this is useful. Please ask if unclear or insufficient.
