Curbs versus Wheelstops:
I prefer cast-in-place concrete curbs (with exposed colored
aggregate) to wheelstops which are precast. In natural areas, I
like stone curbs or pressure treated timber, either dimensioned or
cut from logs. (Don't use extruded asphalt...you know my opinion of
that material.) Wheelstops are frequently fixed to the road surface
with reinforcing steel, a material that is too small in diameter to
resist the impact of the wheels, and so thin that it tends to act
like a knife in cutting the surfacing material. Log and timber
curb (consider ties at 6 x 8) can be imbedded in the surface or
placed on the base before the surface course is applied. Log or
timber has greater resistance to the impacts of car wheels than
wheelstops.
