Another Low-Cost Option
After the last post, another low-cost option for driveways came to my mind. Low-cost enough to carry on the discussion with -
Asphalt is the least expensive of all the different surfaces offered applied above the base itself. It has all the benefits and detriments of monolithic surfaces, in that it is intact and total as a surface. It is one color and consistent in that. It can be applied in shapes without form material, leaving curved edges, indentations at a designer’s whim, and without the forming and handwork of cement.
Asphalt’s only real disadvantages are that is has a definite life span and that it is monolithic, a problem when dealing with heaving and contracting sub soils in severe cold. Blazing heat can also act to loosen the integrity until it flakes, chips or loses durability in general as well.
There are protecting sealers, such as Slurry Seal that can be applied over the top and which can act to extend the life of an asphalt driveway, but these are required pretty much every year in more severe climates.
