The new School for Advanced Segmental Paving was recently completed at the Pave Tech distribution center in Franksville, WI. Progress is continuing on the program that will provide indoor hands-on training and discussion opportunities for foremen, superintendents and field-oriented company owners. Pat O?EUR??,,????'?????<???EUR?Hara has signed on as the school headmaster and is currently defining the classes and schedules that will begin this winter in the off-season months. In mid-May, O?EUR??,,????'?????<???EUR?Hara and curriculum supporters Russ Heitman and Barry Hofer, met with foremen to define what will be taught in those courses.
Students can expect a combination of class discussions and outdoor, hands-on activities.

CORINTH, Miss?EUR??,,????'?????<??oeAllen 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 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.

Behavioral researchers from the Oregon Research Institute investigated the health effects of cobblestones after observing people exercising and walking back and forth over traditional stone paths in China, and it turns out that the path to better health and lower blood pressure may be paved with cobblestones.
When people over 60 walked on smooth, rounded cobblestones for just a half-hour a day over four months, they significantly lowered their blood pressure and improved their balance, a study showed.
Researchers expected to see some general improvement in health but also saw blood pressure drop measurably among the volunteers during the 16-week study, which was a dramatically short period of time.
The researchers in Eugene simulated the rounded, river rock cobblestones with a specially designed mat that was 6 feet long and 1 1/2 feet wide. Some of the test subjects walked in their bare feet, others wore socks. They were compared with a control group who simply walked for an hour, three times per week. Nearly all said they felt better after the exercise, but only the half who walked the cobblestones showed significant improvement in balance, measures of mobility and blood pressure.
Cobblestone walking paths are common in China, where traditional medicine teaches that the uneven surface of the stones stimulate acupuncture points on the soles of the feet.
The theory is much like acupuncture, suggesting that distant and unrelated areas of the body are linked together at certain points and can be stimulated to improve physical and mental health.
In mid-July, the American Concrete Institute celebrated the 25th anniversary of its certification program. Approved for implementation in 1980, the goal of the program was, and still is, to improve the quality of concrete construction.
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.
The impact on the concrete industry is tremendous, so much so that many government agencies and corporations are now requiring ACI-certified personnel on projects.?EUR??,,????'?????<? The Institute currently administers 14 certification programs.
