      <title>FACTORS INFLUENCING DEVELOPMENT OF BITUMINOUS MIXING EQUIPMENT. PROCESS CONTROL AND END PRODUCT QUALITY CONSIDERATIONS</title>
      <link>https://trid.trb.org/View/25957</link>
      <description><![CDATA[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/]]></description>

      <title>THE CONSTRUCTION OF DURBAN'S SOUTHERN FREEWAY</title>
      <link>https://trid.trb.org/View/25961</link>
      <description><![CDATA[This paper is an account of a freeway constructed under difficult conditions.  A deep strength asphalt design was adopted since the method of construction offered many advantages for design engineer and contractor alike and has been used extensively both in Europe and in the U.S.A. Details are given of the pavement and asphalt mix designs, the methods used for quality control at the plant and in the field, and the construction techniques employed. /IRRD/]]></description>
