BITUMEN CHEMISTRY

S.A.R.A.

IT IS FUNDAMENTALLY INSUFFICIENT TO DEFINE THE QUALITY OF A BITUMEN BY ITS PHYSICAL PROPERTIES ONLY. THAT IS BY ITS NORMALLY DEFINED PROPERTIES OF PENETRATION, VISCOSITY, SOFTENING POINT ETC.

YOU HAVE GOOD QUALITY BITUMEN IF THE SUBSTANCE GROUPS (S.A.R.A) ARE PRESENTED IN THE RIGHT BALANCE TO EACH OTHER.

ASPHALTENES ARE IMPORTANT (10-20) BUT THERE SHOULD NOT BE TOO MANY. A WELL BALANCED RATION AND EMBEDMENT BY , THE RESINS IS AT LEAST EQUALLY IMPORTANT.
