STABILIZATION OF GRANULAR BASE ON COUNTY ROADS USING PORTLAND CEMENT. LIME FLY-ASH AND SODIUM CHLORIDE

A ONE AND ONE-HALF MILE EXPERIMENTAL SECTION OF HIGHWAY WAS CONSTRUCTED IN ESSEX COUNTY, ONTARIO IN 1964 TO COMPARE THE EFFECTIVENESS OF THREE DIFFERENT TYPES OF BASE STABILIZING AGENTS, I. E., PORTLAND CEMENT, LIME-FLYASH AND SODIUM CHLORIDE. IN ALL, TEN DIFFERENT MIXES WERE INVESTIGATED. THIS PAPER INCLUDES A DISCUSSION OF THE DESIGN OF THE STABILIZATION MIXES, THE LABORATORY STUDIES CONDUCTED AND A DESCRIPTION OF THE FIELD STUDIES INCLUDING CONSTRUCTION PROCEDURES AND THE FIELD TESTING PROGRAMME. THE CEMENT AND LIME-FLYASH STABILIZED BASES ARE CHARACTERIZED BY HIGH STRENGTHS, LOW BENKELMAN BEAM REBOUND VALUES AND CONSIDERABLE TRANSVERSE AND LONGITUDINAL CRACKING IN THE PAVEMENT SURFACE. THE SALT STABILIZED BASES AND THE PLAIN CONTROL SECTION ARE CHARACTERIZED BY LOW STRENGTHS, HIGHER REBOUND VALUES BUT NO CRACKING IN THE PAVEMENT SURFACE. ON THE BASIS OF BENKELMAN BEAM REBOUND READINGS AND COMPRESSIVE STRENGTHS, BEST PERFORMANCES TO DATE ARE SHOWN BY THE 5% CEMENT STABILIZED BASE AND THE TWO 4.5% LIME, 15% FLYASH STABILIZED BASES. ON THE BASIS OF A VISUAL ASSESSMENT OF THE PAVEMENT SURFACE CONDITIONS, THE THREE SALT STABILIZED BASES AND THE PLAIN CONTROL SECTION ARE SHOWING THE BEST PERFORMANCE IN THAT THEY EXHIBIT NO INDICATION OF DISTRESS OF ANY KIND TO DATE. /AUTHOR/
