CHINESE ENGINEER ADVOCATES POTTERY FOR ROAD BUILDING

POTTERY CAN BE AN EXCELLENT SUBSTITUTE FOR CONVENTIONAL AGGREGATES WHEN BUILDING BITUMINOUS PAVEMENTS IN AREAS WHERE STONE OR GRAVEL SOURCES ARE RARE, ACCORDING TO PROFESSOR ZENITH CHUANG, PROFESSOR OF CIVIL ENGINEERING AT TAIWAN UNIVERSITY. EXPERIMENTS, HE REPORTS, SHOW THAT THE MOST SUITABLE MIX IS 46% POTTERY AGGREGATE, 37% COARSE SAND, 11% FINE SAND AND 6% LIME POWDER. CHINESE EXPERIENCE IN THE MANUFACTURE OF PORCELAIN MAKES IT A RELATIVELY SIMPLE MATTER TO PRODUCE POTTERY AGGREGATES ECONOMICALLY. PASTE-LIKE CRUDE CLAY, WITH A WATER CONTENT NOT EXCEEDING 5%, IS PREPARED AND DUMPED INTO THE KILN. THE ENTIRE PROCESS TAKES ABOUT SIX DAYS. PROFESSOR CHUANG NOTES THAT POTTERY HAS PROVED EQUALLY SUITABLE FOR BASE COURSE AND FOR BITUMINOUS SURFACING. HE SUGGESTS THAT IT COULD BE USEFULLY EXPLOITED IN MANY OTHER AGGREGATE-SCARCE PARTS OF THE WORLD. /AUTHOR/
