Special materials content

The tables below shows the bitumen contents of Colas’s binders, which are to be used when calculating ‘rise and fall’ on the various grades.

Table 1: SANS 4001 - BT3:2014 and SANS 4001 - BT4:2014 emulsion grade

GradeBitumen Content % (m/m) 
     
Cationic Spray Grade 60%, Cationic Premix Grade 60%, Cationic Stable Grade 60%, Anionic Stable Grade 60% 60.0  
Cationic Spray Grade 65%, Cationic Premix Grade 65% 65.0  
Cationic Spray Grade 70% 70.0  

The bitumen content is based on the lower limit of the binder content range.
