FACTORS INFLUENCING DEVELOPMENT OF BITUMINOUS MIXING EQUIPMENT. PROCESS CONTROL AND END PRODUCT QUALITY CONSIDERATIONS

The author investigates the influence on research of (1) the requirement for greater machine productivity and more economical operation, (2) the need for improved process controls, including application of modern technological advances and process control equipment to the production of bituminous mixtures. Emphasis is laid on the necessity of establishing more reproducible sampling and testing methods and applying satistical methods to determine process variability. The attitude of specification agencies with respect to the degree of freedom offered to the contractor in the selection of process equipment and process control is also studied. /IRRD/
