The purpose of my experiment was to test how laying a layer of permeable friction course (PFC) would affect the safety of motorists.
For my procedure first I obtained two samples one of PFC and one of regular conventional asphalt. Then I got any other materials needed like a timer, and a container for water. After this I got a measured amount of water and put it on top of the samples’, recording the amount of time it took to drain down at the same time. After this I wrote everything down and worked on my presentation.
Analyzing my data I realized that my hypothesis was right and that a permeable friction course does affect and increases safety on roads. It drained the water down much faster than conventional asphalt making roads much safer for motorists.
My conclusion was that as I said before my hypothesis was correct. Permeable friction courses are safe and should be used on most if not all high-volume roads for example, bridges. The water drained down the permeable friction course sample less than half the time it took regular asphalt. This meant that on roads it would decrease water splash increasing visibility. Also it would decrease hydroplaning leading to fewer accidents.
