A STUDY OF AN OLD LIME-STABILIZED GRAVEL BASE

THE LIFE EXPECTANCY OF ANY CONSTRUCTION MATERIAL IS OF INTEREST TO ALL ENGINEERS BECAUSE OF ITS IMPORTANCE IN DESIGN PROCEDURES AND COST ANALYSIS OF STRUCTURES. IN THE STABILIZING OF UNSATISFACTORY MATERIALS IN ORDER THAT THEY MAY SERVE AS A SATISFACTORY BASE FOR HIGHWAY CONSTRUCTION, THE LIFE EXPECTANCY IS OF UNUSUAL INTEREST TO ALL ENGINEERS BECAUSE THESE PROCEDURES WILL PERMIT UTILIZATION OF UNSATISFACTORY MATERIALS AT USUALLY A CONSIDERABLE SAVING IN TOTAL COST. THIS REPORT COVERS THE UTILIZATION OF WASTE LIME IN STABILIZING AN UNSATISFACTORY GRAVEL BASE MATERIAL. THE LIME NOT ONLY PROVIDED A SATISFACTORY STABILIZED BASE, BUT ALSO PROVED ECONOMICAL TO USE. NOW, 15 YEARS AFTER THE BASE WAS CONSTRUCTED, CORES HAVE BEEN TAKEN AND TESTED TO DETERMINE THE DURABILITY AND LIFE EXPECTANCY OF THIS STABILIZED GRAVEL. THE PAPER GIVES BOTH THE RESULTS OF TESTS ON THESE CORES AND THE ORIGINAL LABORATORY TESTS ON THE STABILIZED GRAVEL. /AUTHOR/
