Title: THE EFFECTS OF PUGMILL STRUCTURE AND ASPHALT SPRAYING MECHANISMS ON THE MIXING AND PROPERTIES OF MIXTURES
Accession Number: 00211422
Record Type: Component
Abstract: THE ASPHALT PUGMILL MIXING PROCESS IS DISCUSSED. THE FOLLOWING FUNDAMENTAL PROPERTIES AFFECT THE MIXING PROCESS: (1) CONSISTENCY OR APPARENT VISCOSITY AT MIXING VISCOSITIES, (2) THE SPECIFIC GRAVITIES OF THE VARIOUS PHASES, (3) EASE OF WETTING OF THE SOLID PHASE BY THE LIQUID PHASE, (4) SURFACE TENSION OF THE LIQUID PHASE, (5) RANGE OF PARTICLE SIZE VARIATION, (6) VARIATION OF CONSISTENCY OR VISCOSITY DURING THE MIXING, AND (7) RELATIVE PROPORTIONS OF MATERIALS AND THEIR ORDER OF ADDITION TO THE MIXTURE. PUGMILL CAPACITY AND DESIGN ARE DISCUSSED. FACTORS WHICH NEED TO BE INVESTIGATED IN PUGMILL DESIGN ARE DISCUSSED. UNIFORM MIXTURES AND SAMPLING PRACTICES ARE DISCUSSED. A NEED FOR CONSIDERED EFFORTS WITHIN THE ASPHALT PAVING INDUSTRY TO DEVELOP CRITERIA UPON WHICH TO BASE DESIGN OF EQUIPMENT, OPERATING CHARACTERISTICS, AND SPECIFICATIONS FOR THE ASPHALT MIXING PROCESS IS CONCLUDED.
