A Blankenship Asphalt Tech & Training study compared two bio-oil formulations in an engineered 45% RAP mixture and measured the balance between IDEAL-CT cracking tolerance and Hamburg rutting resistance.
In a blinded ATS comparison, two SIP-1111™ treatments produced the study's two lowest Hamburg deformation values while preserving the full cracking and dosage-efficiency context.
NCAT Section S1 combined 50% RAP with 4.1% SIP-1111™ and recorded no visible cracking with less than 3.5 mm rut depth after one year and about 4 million ESALs.
A Mason City demonstration reports higher CT Index and DCT fracture energy for its 45% RAP SIP-1111™ design than for the matched 45% RAP TuffTrek design.
