QUALITY REQUIREMENTS OF BITUMEN IN RELATION TO LOCAL CONDITIONS (CLIMATE, TRAFFIC, ECT.)

SPECIFICATIONS FOR BITUMEN IN GENERAL INCLUDE SEVERAL PROPERTIES HAVING NO DIRECT LINK WITH ITS BEHAVIOR IN THE ROAD FOR THE DESIRED PROPERTIES TO BE SPECIFIED IT IS ESSENTIAL TO KNOW THE REQUIREMENTS TO BE MET BY THE PAVEMENTS AS REGARDS DEFORMATION AND STABILITY IN RELATION TO TRAFFIC INTENSITY, CLIMATIC CONDITIONS ESPECIALLY VARIATIONS IN TEMPERATURE AT ROAD LEVEL, HUMIDITY, FROST DEPTH AND OTHER FACTORS. FOR CRACK FORMATION AT LOW TEMPERATURES TO BE AVOIDED, THE ELONGATION MUST BE SUFFICIENT (HIGH STRENGTH MODULUS, LOW MODULUS OF RIGIDITY). AT HIGH TEMPERATURES THE PLASTICITY OF THE PAVEMENT MUST BE SUFFICIENTLY LOW FOR THE TRAFFIC EXPECTED. MEDIUM TEMPERATURES REQUIRE GOOD RESISTANCE TO WATER AND FROST, WHICH IMPLIES STRONG ADHESION. /RRL/A/
