DURABILITY OF SHALES AS DETERMINED BY LABORATORY TEST

RESEARCH WAS CONDUCTED TO DETERMINE IF ANY OF THE SHALE DEPOSITS IN PENNSYLVANIA ARE SUITABLE FOR USE AS GRANULAR MATERIAL IN HIGHWAY CONSTRUCTION, AND (IF ANY ARE SUITABLE) TO DEVELOP A SIMPLE FIELD TEST FOR IDENTIFYING THESE SHALES. SAMPLES OF SHALES WERE SELECTED FROM SITES THROUGHOUT THE STATE. PHYSICAL TESTS WERE PERFORMED ON THE SHALES AND ON SELECTED SOUND AGGREGATES; THE TEST DATA INDICATE THREE OF THE SHALES MAY BE SUITABLE FOR USE AS GRANULAR MATERIAL IN HIGHWAY CONSTRUCTION. THE MOST DURABLE SHALES AS INDICATED BY THE TESTS, ARE THOSE THAT ARE DOLOMITIC, HAVE HIGH BULK SPECIFIC GRAVITY AND GENERALLY LOW ABSORPTION VALUES. FURTHER STUDY IS NEEDED TO OBTAIN SOME REALLY CONCLUSIVE RESULTS, THUS THERE WILL BE A SECOND PHASE TO THIS RESEARCH PROJECT. /AUTHOR/
