SS60 is typically used where slow setting behavior supports mixing or longer working time, such as certain prime or maintenance applications and some cold mix related uses depending on local specifications. Standard parameters usually cover residual binder content, viscosity range at a reference temperature, sieve residue limits, storage stability, particle charge, and residue properties like penetration or softening point. Actual requirements vary by country and road authority, so procurement must reference the exact governing spec and test methods. Confirm compatibility with aggregates and intended application rate through trial sections and mixing stability checks.
