NEW OUTLOOKS FOR ROAD TAR
VARIOUS EXAMPLES SHOW THAT COAL TAR IS A BINDER WHICH RETAINS ITS VALUE DESPITE THE NEW REQUIREMENTS OF ROAD BUILDING TECHNIQUES. LINKED WITH MANY MATERIALS IT MAY ATTAIN A PERFORMANCE SUPERIOR TO THOSE OF TRADITIONAL BINDERS AND COPE WITH THE STRESSES IMPOSED BY INCREASING TRAFFIC IN REGARDS TO NUMBERS, SPEED, AND WEIGHT OF VEHICLES. RESEARCH IS BEING CARRIED OUT IN MANY DIFFERENT DIRECTIONS: THE OBJECT IS FITTING TAR TO THE DEMANDS MADE ON MODERN ROADS. MANY COUNTRIES CONSIDER THAT TAR-BITUMEN MIXTURES ARE THE SOLUTION FOR THE FUTURE. MUCH PROGRESS IS POSSIBLE IN THIS FIELD. ON THE OTHER HAND THE ASSOCIATION OF CONVENTIONAL BINDERS WITH CERTAIN NATURAL OR SYNTHETIC PRODUCTS OPENS NEW PROSPECTS. TAR HAS A SPECIFIC AFFINITY FOR THESE MATERIALS, AND THIS ADVANTAGE, OF WHICH USE HAS ALREADY BEEN TAKEN, MUST BE USED EVEN MORE IN THE FUTURE TO PERFECT ROAD BUILDING TECHNIQUES. /AUTHOR/
