What is the slope range of an accessible ramp?

[LeAlexa]

The slope of an accessible ramp should not exceed 1/12. Below is relevant information: Urban roads: In urban roads, tactile paving is constructed for the convenience of blind pedestrians, and curb ramps are built for wheelchair users. In terms of buildings, many large public structures feature ramps that allow wheelchair users and the elderly to move from outdoors to indoors, along with accessible facilities (stairs, elevators, telephones, restrooms, handrails, wheelchair spaces, guest rooms, etc.). Accessibility requirements: The scope of accessibility implementation mainly includes roads, green spaces, etc. Accessibility requirements stipulate that sidewalks with curbs should have curb ramps at intersections; main public service areas should have tactile paving on sidewalks, and bus stops should feature detectable warning surfaces; pathways in parks, small gardens, and children's play areas should accommodate wheelchair access, and entrances to these pathways should have detectable warning surfaces.
