The Professional Supplier Speed Ramp:
While Speed Ramp generally slow cars to 5–10 mph (8–15 km/h), humps slow cars to 10–20 mph (15–30 km/h). The narrow nature of Speed Ramp often allows vehicles to pass over them at high speed while only perturbing the wheels and suspension, hardly affecting the vehicle cab and its occupants. The relatively long slopes of Speed Ramp gradually accelerates the entire vehicle in vertical direction, causing the perturbation of the cab to become progressively more severe at higher speeds.
Speed Ramp is constructed of asphalt, concrete, or rubber. While traditionally most humps were constructed of asphalt or concrete, rubber is becoming increasingly common in some regions for several reasons. Asphalt and concrete can be difficult to construct precisely while rubber products are pre-shaped to standardized sizes and thus consistently meet industry standards. An additional advantage is ease of installation, which is particularly beneficial when a city wants to test streets before deciding where to keep the devices.
The simple installation process also allows for relocation during the winter when snow is a concern, which prevents damage to the Speed Ramp by snowplows. In addition, unlike concrete and asphalt, which necessitate frequent and high cost replacement, rubber products are longer lasting and thus more cost-efficient.
