USE OF AUTOMATIC RECORDING APPARATUS IN DESIGN AND CONTROL OF BITUMINOUS CONCRETE
AN INVESTIGATION WAS UNDERTAKEN TO DEVELOP INSTRUMENTATION FOR THE MARSHALL APPARATUS WHICH WOULD ELIMINATE THE HUMAN ELEMENT AND BIAS IN OBTAINING STABILITIES AND FLOW VALUES. THE STUDY PRODUCED A FIELD MODEL AUTOMATIC RECORDING APPARATUS, AS WELL AS A RESEARCH MODEL WHICH PLOTS THE LOAD- DEFORMATION CURVE AND, THEREFORE, MAKES A PERMANENT RECORD OF THE TEST FOR LATER REFERENCE OR ANALYSIS. THE ADVANTAGES OF THE EQUIPMENT, AS WELL AS THE POTENTIAL USE OF THE LOAD- DEFORMATION CURVES, ARE DISCUSSED. /AUTHOR/
