SCOPE This specification covers liquid petroleum products, produced by fluxing an asphaltic base with suitable petroleum distillates, to be used in the treatment of road surfaces. The values stated in SI units are to be regarded as the standard.

As an alternate, Saybolt-Furol viscosities may be specified as follows: Grade MC—Furol viscosity at aasto F —60 to s. Grade MC—Furol viscosity at 60? F — to s.

Grade MC—Furol viscosity at In lieu of viscosity of the residue, the specifying agency, at its option, can specify penetration at g, 5 s at 25? However, in no case will both be required. If the ductility at 25?

F is less thanthe material will be acceptable if its ductility at F is more than The use of the spot test is optional. When specified, the engineer shall indicate whether the standard naphtha solvent, the naphtha-xylene solvent, or the heptane-xylene solvent will be used in determining compliance with the requirement, and also, in the case of the xylene solvents, the percentage of xylene to be used.
