A NEW METHOD OF MEASUREMENT FOR THE CLASSIFICATION OF EXCAVATED MATERIAL; EARTH, SOFT ROCK, HARD ROCK /IN ITALIAN/

EXCAVATED MATERIAL FROM ROAD WORKS IS GENERALLY CLASSIFIED AS EARTH, SOFT ROCK, OR HARD ROCK, BUT THE LIMITS SEPARATING THESE CLASSIFICATIONS ARE NOT EASILY DEFINABLE, ESPECIALLY IN THE CASE OF SOFT AND HARD ROCK. THE METHOD PROPOSED FOR DETERMINING THESE LIMITS CONSIST IN CALCULATING THE DEGREE OF HARDNESS OF THE SUBSOIL FROM THE VELOCITY OF ELASTIC WAVES MEASURED BY THE USE OF A SEISMOGRAPH. /RRL/
