Concrete paver driveways require
very little maintenance. An occasional sweeping or hose rinsing will keep them
clean enough. If weeds find their way through the surface, just remove them as
soon as they appear. Stains can usually be removed with a concrete
cleaner, but you should check with the manufacturer
for recommendations.
Should tree roots, frost heave, or settling damage a
section of the driveway, it is easy to remove the affected pavers, fix the
underlying problem, and put the driveway back together.
Thickness of concrete pavers varies according
to the application:
·
Pedestrian areas,
driveways, and areas subject to limited vehicular use are paved with units 2
3/8" thick.
·
Streets and industrial
pavements should be paved with units 3 1/8" thick.
Pavers
made in the United States should meet or exceed the requirements established in
the American Society for Testing and Materials (ASTM) C 936, Standard
Specifications for Solid Interlocking Concrete Paving Units.
Here
are the requirements for this standard:
·
An average compressive
strength of 8,000 psi
·
An average absorption
no greater than 5%
·
Resistance to at least
50 freeze-thaw cycles with average material loss not exceeding 1%
·
Conformance to
abrasion resistance tests
