Cutback Bitumen

Note1: if the ductility at 25°C (77°F) is less than 100, The material is still acceptable if its ductility at 15°(59°F) is more than 100

Instead of viscosity of the residue , the specifying agancy, at its option , can specify penetration 100g: 5 s at 25 C(77°F) of 120 to 300 for MC-30, MC-7, MC-250 grades and 120 to 250 for MC-800 and MC-3000 However, in no case, will both be required.
