Asphalt Versus Brick






Asphalt has a limited life, as this close-up of a street in Torrance, Calif. taken in 2002 clearly shows.


The average cost to reconstruct a block of Wilmette?EUR??,,????'?????<

When comparing costs on road surfaces, asphalt serves as a better short-term investment while brick comes out on top in the long run, said Mayerhofer. She explained it is cheaper to pave in asphalt, but those streets must be resurfaced every 15 to 20 years and reconstructed after 25 to 30 years. If a brick street has been installed properly, follow-up work should come 40 years later, when the bricks need to be rotated and flipped, she said.

Comparing the two types of streets over an 80-year period, the cost of a brick street is more economical because the only other maintenance work involves filling the street?EUR??,,????'?????<

Broker Makes Bricks






A litter box is not the only place kitty litter can be put to use, the founder of Corinth Brick Co. has discovered.


Allen Lee used to work as a broker for brick manufacturers, but decided to start making brick himself, opening the Corinth Brick Co. in 2000. There was one big problem: The local clay wouldn?EUR??,,????'?????<

Lee wondered if a lightweight kitty litter would work, and went to Oil-Dri Corp., in Chicago, a manufacturer of cat litter, but also ?EUR??,,????'?????<

Oil-Dri and Lee worked together on various mixes that would not only absorb the moisture but be viable with the heat required in brickmaking, plus not emit any toxicities. The result, after three years, is the brick additive BA 1000.

Brick using BA 1000 is said to be more porous than heavier clay mixtures and 4-6 percent lighter in weight, which lowers shipping costs. The BA 1000 additive is slightly more expensive than other options on the market, but Lee asserts the benefits in manufacturing, transport and the quality of the brick more than offset the product cost. Corinth Brick manufactures 12 to 15 million bricks a year in five colors.
