Ramps
AS1428.1-2009 generally includes the following ramp requirements:
Kerb Ramp: As the name implies, a kerb ramp is a ramp that gives access from a footpath to a roadway. Kerb ramps are usually the responsibility of the local council and must have a slope of no more than 1:8, splayed edges, top landing (1200-1500mm long) and a slip resistant surface. They are also known as pram ramps and may require tactile indicators to warn users of the inclined surface.
Step Ramp: Similar to a kerb ramp but not attached to a kerb. It can assist someone to ascend a small step (no more than 190mm) but can't be longer than 1900mm or steeper than 1:10 grade with top and bottom landings (1500mm long due to grade). Edge protection including either a wall, balustrade or handrail with a kerbrail is required on each side to prevent the user from falling off the side and must have a slip resistant surface. Tactile indicators at landings are not required.
Threshold Ramp: A short slip resistant ramp which allows access to a doorway. They can only service a rise of 35mm and a maximum distance of not more than 280mm (a maximum slope of 1:8). A threshold ramp will enable people with prams, strollers and mobility devices such as wheelchairs to access buildings more easily.
Ramp: This is commonly understood as a pathway that lets people walk between two levels greater than 190mm high on a gradual slope. Typical a 1:14 minimum slope is provided with handrails on both sides with extensions and kerbrails, landings and mid-landings (1200-1500mm long or 1540mm x 2070mm where a 180 degree turn us required) every 9m, tactile indicators at top and bottom landings and a slip resistant surface.
All ramps must have a minimum 1000mm clear width unless turning space is required.
