5elLction of the right emulsion asphalts is critical to the <br /> success of this project. The only emulsion found to be <br /> compatible with the soils of the ISE Winery was SS-1H. Do no-t <br /> use Cationic or High Float emulsions, these emulusions react with <br /> the hydrocarbons and will not mix properly. <br /> It is recommended by Foothill Engineering that the impacted soils <br /> of the ISC Winery be mixed with 4%-5% of SS-1H by dry weight and <br /> placed by conventional methods on approved roadway subgrades. <br /> For application an roads and streets of TI=6.09 a bituminous seal <br /> coat wearing surface should be applied. <br /> OTHER RESREACH ON THIS SUBJECT <br /> A draft report prepared by Terry C. Sciarrotta, of Southern <br /> California Edision Company, titled: "RECYCLING OF PETROLEUM <br /> CONTAMINATED SOILS IN COLD MIX ASPHALT PAVING MATERIALS," is <br /> enclosed in Appendix B of this report. In the Sciarrotta report <br /> SC--3000 liquid asphalt was used as the binder. The pavement <br /> produced by Sciarrotta was of good quality and performed well <br /> under traffic. Foothill Engineering found no structural or <br /> engineering advantage to adding more light oils contained in 5C- <br /> 3000 to the" fuel oil impacted soils of the ISC Winery. The SS-1H . <br /> emulsion is made from harder base asphalts than SC-3000 and would <br /> encapsulate the fuel oils present in the impacted sails. <br /> Respectfully submitted, <br /> F�HILL-FN INEE IN8 <br /> Ery Rferf urg, RCF_ 19752 <br /> 7 <br />
