GAJPOWSKI OF POLAND WHO DISCUSSED BOTH CHEMICALLY STABILIZED BASE COURSES AND USE OF PARAFFIN OIL BITUMENS; (3) MR. MIKHAILOV OF USSR WHO DESCRIBED HIS COUNTRY'S RESEARCH PROGRAMS ON THE PROCESSING OF BITUMENS AND PRODUCTION OF BITUMEN STRUCTURES; (4) MR. TAKAHASHI OF JAPAN, WHO DISCUSSED RECENT DEVELOPMENTS IN ROAD TECHNOLOGY IN HIS COUNTRY; (5) MR. FERREIRA OF PORTUGAL WHO DESCRIBED EXPERIMENTS WITH SOIL CEMENT BASES; (6) MR. FENLO OF SPAIN WHO EMPHASIZED THE NEED FOR STANDARDIZATION OF TERMINOLOGY FOR COATED MATERIALS USED FOR FLEXIBLE PAVEMENTS; (7) MR. BENINI OF ITALY WHO DISCUSSED RESULTS OF PAVEMENT INVESTIGATIONS SUBSEQUENT TO THE SUBMISSION OF HIS COUNTRY'S REPORT; (8) MR. NICHOLS OF GREAT BRITAIN WHO SPOKE ON BINDER MATERIALS AND MAINTENANCE OF SKIDDING RESISTANCE; AND (8) MR. LAW OF GREAT BRITAIN WHO DISCUSSED SUBBASE STABILIZATION, COMPACTION AND SURFACE TEXTURE OF WEARING COURSES, AND AUTOMATION OF MIXING PLANTS. THE SPEAKERS COMMENTS WERE SUMMARIZED BY DR.
