On October 24, 2020, Rock Road Companies produced a head-to-head rejuvenator comparison for a City of Janesville paving section on North Claremont Drive. The 5 LT hot-mix asphalt used a 46-34 virgin binder and 40% aged-binder replacement<\/strong>. One project mixture contained 0.5% SIP-1111\u2122<\/strong> on total asphalt-cement content; the comparator used the same dosage of Anova.<\/p>\n

The project put equal-dose rejuvenator formulations into a full-scale city paving program, then carried material from the comparison into laboratory performance testing. The result is a practical data set for producers evaluating high-recycled-content mixtures without changing the additive dosage between products.<\/p>\n

Equal dosage with direct cracking-test results<\/h2>\n

Iowa State University tested three project-mixture specimens from each 0.5% formulation in the disk-shaped compact tension test. The SIP-1111\u2122 specimens averaged 358 J\/m\u00b2<\/strong> of DCT fracture energy, compared with 355 J\/m\u00b2<\/strong> for Anova. Air voids across the six specimens ranged from 6.87% to 7.48%.<\/p>\n

Three additional specimens per formulation were evaluated with IDEAL-CT. SIP-1111\u2122 produced an average CT index of 193.5<\/strong>, compared with 188.2<\/strong> for Anova, at specimen air voids ranging from 6.8% to 7.4%.<\/p>\n

Pretrial testing against both Anova and an untreated control<\/h2>\n

Rock Road Companies also evaluated the 5 LT 46-34 design before field production. In that laboratory study, the 0.5% SIP-1111\u2122 mixture recorded 410.7 J\/m\u00b2<\/strong> of DCT fracture energy. The matching 0.5% Anova design measured 403.3 J\/m\u00b2, while the no-additive design measured 356.7 J\/m\u00b2.<\/p>\n

Hamburg wheel-track testing ran through 20,000 passes. The SIP-1111\u2122 design recorded a stripping inflection point of 19,949 passes<\/strong> and 5.5 mm<\/strong> final rut depth. The Anova design recorded 17,020 passes and 6.5 mm; the no-additive design recorded 16,085 passes and 6.5 mm.<\/p>\n

Plant-ready delivery for a high-recycled-content mix<\/h2>\n

Rock Road Companies injected the liquid additive into the asphalt-cement line immediately before the binder entered the plant’s dual drum. That production arrangement moved SIP-1111\u2122 directly from a tote into the 40% recycled-binder mixture and supplied project material for independent testing.<\/p>\n

What Janesville demonstrates<\/h2>\n

Janesville established an equal-dose field comparison in a demanding recycled-binder application. At 0.5% additive, the SIP-1111\u2122 project samples averaged 358 J\/m\u00b2 DCT fracture energy and 193.5 IDEAL-CT<\/strong>; the Anova samples averaged 355 J\/m\u00b2 and 188.2<\/strong>. The supporting pretrial study added no-additive context and recorded the highest DCT fracture energy, highest Hamburg stripping inflection point, and lowest final rut depth among the three 5 LT 46-34 designs.<\/p>\n

Higher DCT fracture energy and IDEAL-CT Index are favorable; zero-based scales avoid exaggerating the small differences.<\/p>\n
