THE USE OF CEMENT-STABILIZED CHALK IN ROAD CONSTRUCTION

CHALK OCCURS WIDELY IN THE SOUTHEAST OF ENGLAND AND, BECAUSE OF THE SHORTAGE OF GOOD QUALITY ROAD-MAKING MATERIALS, CONSIDERABLE ECONOMY IN CONSTRUCTION WOULD BE ACHIEVED IF CHALK COULD BE STABILIZED WITH CEMENT TO PRODUCE A SATISFACTORY BASE AND SUBBASE MATERIAL. THIS REPORT DESCRIBES BOTH A LABORATORY INVESTIGATION TO DETERMINE IF SUCH A MATERIAL COULD BE MADE AND A SUBSEQUENT FULL-SCALE EXPERIMENT WHERE SECTIONS OF SUB-BASE AND BASE CEMENT-STABILIZED CHALK WERE LAID. THIS ROAD EXPERIMENT WAS DESIGNED TO SEE WHETHER THERE WERE ANY PRACTICAL PROBLEMS ASSOCIATED WITH THE MATERIAL AND TO ASSESS ITS LONG-TERM PERFORMANCE AND DURABILITY. THE EXPERIMENTAL WORK EXPOSED PROBLEMS OF MIXING AND LAYING BUT NONE OF THESE SHOULD PROVE VERY DIFFICULT TO SOLVE. THE PERFORMANCE OF THE ROAD DURING THE THREE YEARS SINCE CONSTRUCTION HAS BEEN EXCELLENT AND THERE IS EVERY INDICATION THAT THE MATERIAL SHOULD PROVE A USEFUL ADDITION TO THE RANGE OF ROAD-MAKING MATERIALS AVAILABLE IN THE AREA. /RRL/A/
