The average cost to reconstruct a block of Wilmette?EUR??,,????'?????<???EUR?s Linden Avenue is about $240,000, said local engineering director Brigitte Mayerhofer. The village has about $770,000 from the motor fuel tax to use on the program and $2.3 million from the accelerated road program, via bond funds.
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??,,????'?????<???EUR?s joints with sand, she added.
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??,,????'?????<???EUR?t hold its shape because of a too high moisture content. This is not an unusual problem. Sawdust and other aggregates have been used to remedy such problems, but the usual additives did not work on the regional clay.
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??,,????'?????<?mineral absorbents and polypropylene sorbents?EUR??,,????'?????<? and a variety of products to the ?EUR??,,????'?????<?fluids purification?EUR??,,????'?????<? markets.
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.

Today, the American Concrete Institute has certified over 250,000 individuals in 44 countries. John W. Nehasil, managing director of certification said in a statement, ?EUR??,,????'?????<?Today, we are testing over 20,000 concrete technicians, inspectors, supervisors and craftsmen each year.
