What does PFC mean in ENGINEERING

A Permeable Friction Course (PFC) is a porous pavement system designed to provide safe surfaces for vehicles and pedestrians while allowing water to pass through its surface. PFCs are generally composed of a base layer of open cells filled with stone or gravel, a sealing layer and an open-graded, friction-course wearing course.

There are numerous advantages to using PFCs for road paving. These include improved drainage, reduced splash and spray from vehicle tires on wet roads, increased safety from skidding due to improved traction, reduced runoff entering stormwater systems, and cost savings from decreased need for maintenance activities such as resurfacing.

PFCs are very effective in reducing flooding by improving drainage capabilities at both micro and macro scales. The porous structure and open-graded top surface allow rainwater to quickly infiltrate into the soil and reduce runoff volume. Additionally, the underlying base layers act as an underground storage basin that further reduces flooding impacts.

Yes! By allowing rainwater to infiltrate into the soil instead of running off via surface flows, it eliminates much of the energy costs associated with collecting, treating, and pumping stormwater out of urban areas. This can significantly reduce the amount of energy needed to power stormwater management systems in urban environments.

Absolutely! As mentioned previously, installing a PFC helps reduce runoff volume which prevents pollutants from entering waterways or other sensitive habitats that may be impacted by surface flow runoff. In addition, as an alternative to traditional asphalts that require crude oils for production, some PFCs can use recycled products such as scrap tire rubber or glass beads which yield more sustainable applications.

The lifespan of a typical PFC installation varies depending on the specific application and type of material used; however most manufacturers estimate anywhere between 10-20 years with proper maintenance and upkeep procedures being followed yearly or bi-yearly depending on traffic intensity levels or weathering conditions present where it is installed.

While not mandatory regular maintenance activities like sweeping away debris or cleaning clogged pores should be conducted periodically in order keep your Permeable Friction Course in an optimal working condition. Regular inspections should also take place in order to verify proper function.
