2357 Bituminous Tack Coat. CSS-1, CSS-1h, MC-250
for tack when paving
2355 Bituminous Fog Seal. CSS-1h (1:1), CRS-2Pd (3:1)
fog a chip seal or shoulder
No spec for spray applied sealer –application or material

NCAT-MnROAD used CSS-1H and rejuvator fog
Success of chip seals, is my reason that fog sealing has moved slowly in MN.
