The Mysteries of Asphalt Revealed
Riders invariably have their favorite sections of road,the parts
that flow together into a dance where everything happens just the way
it`s supposed to with no surprises.On the street or track,you know which
ones they are--but you want to know why they`re so comfortable.How
much should you know about the road you ride?Which aspects are important
and which are not ?Why are some sections of road harder to ride
than others?
First,some background.Highways are constructed so that
motorists can travel from point A to point B very easily.The highway
engineers are very thoughtful;they want to see you make it in one piece.The
turns are often gently banked.Decreading-radius corners are rare.Seldom
is there a hairpin at the end of a straight stretch of road.Off-camber
turns are avoided whenever possible.Corners are constructed in a
predictable and straight-forward manner.
Designed to Fool You
A racetrack is another sort of beast.Not much of anything is
done for your convenience.The designers have purposely constructed a
course that will continue to create changing situations for the reder,to fool
and challenge him.Hairpins are put into the most difficult section,uaually
after the fastest straight,and"S" turns,or chicanes,often have a
slower exit than entry.Corners may baffle you with several camber and
radius changes to break you flow and force you into unusual situations.
And always,the faster the turns are negotiated,the more difficult they
become.There are,however,only five major changes that can be designed
into an asphalt road.
