CONSIDERATION OF BAMBOO-REINFORCED SOIL-CEMENT AS MATERIAL FOR CONSTRUCTION WITH SPECIAL REFERENCE TO ITS USE FOR PAVEMENTS. 3 PARTS
A THEORY WAS SUGGESTED FOR DESIGN OF BAMBOO-REINFORCED SOIL-CEMENT BEAMS BASED ON ULTIMATE LOAD THEORY AND BOND FAILURE. THIS WAS IN GOOD ACCORD WITH THE TEST RESULTS. WITH SUITABLE MODIFICATIONS, THIS THEORY COULD BE EXTENDED TO BEAMS OF DIFFERENT SUPPORT CONDITIONS AND SLAB. IT WAS FURTHER SHOWN THAT ELASTIC THEORY WAS NOT SUITABLE FOR THE DESIGN. TESTS RESULTS SHOWED THAT THE SAFE DESIGN LOAD MIGHT BE INCREASED BY ABOUT 4 TIMES FOR A BAMBOO-REINFORCED SOIL- CEMENT STRUCTURE OVER THAT OBTAINED BY ELASTIC ANALYSIS. BAMBOO-REINFORCED SOIL-CEMENT BASE UNDER THIN CONCRETE PAVEMENT SURFACING WAS LIKELY TO EFFECT A SAYING IN THE ORDER OF 30 PERCENT OVER NORMAL PLAIN CEMENT CONCRETE PAVEMENT. LABORATORY TESTS ON A FULL SIZE SLAB DESIGNED FOR 9,000 LB WHEEL LOAD INDICATED THAT ULTIMATE LOAD-CARRYING CAPACITIESS IN THIS TYPE OF CONSTRUCTION FOR BOTH CORNER AND EDGE LOADINGS WERE CONSIDERABLY HIGHER /65 PER CENT HIGHER IN THE CASE OF CORNER FAILURE AND 335 PER CENT HIGHER IN THE CASE OF EDGE FAILURE/ THAN THE DESIGN LOAD. THIS RESERVE STRENGTH WOULD ADEQUATELY CATER FOR ANY TEMPERATURE AND SUBGRADE RESTRAINT STRESSES OCCURRING IN THE PAVEMENT. /AUTHOR/
