Differences in time?

Hello everyone,
I’m trying to gather information on the advantages of poly mat surfaces v. asphalt, beyond the obvious, so that I may further entice business’ to donate/invest in helping my team/school attain a poly mat surface, (not the busniness advantages, those I’ve convered). I’m interested in varified time diffrences, i.e. studies/stats. and other various studies related to injury rates, etc. Thanks for the imput.
