ig <br /> The State of California design methods are used for roadway <br /> sections for TI=4.0, TI=5.0, and TI=6.0 respectively (See <br /> Appendix. A for design procedure California Test 301) . <br /> PAVEMENT SECTION FOR TI=4.0 <br /> Basement soil = 50 R-value (Typical of Lodi soils) <br /> Gravel Equivalent Required = 0.65' OE <br /> Asphalt pavement thickness required = 0.65/2.5 = .26' <br /> PAVEMENT SECTION FOR TI=5.0 <br /> Basement soil = 50 R-valve <br /> Gravel Equivalent Required = 0.8' GE <br /> Asphalt pavement thickness required = 0.$/2.5 = .32' <br /> PAVEMENT SECTION FOR TI=6.0 <br /> Basement soil = 50 R-value <br /> Gravel Equivalent Required = 0.95' GE . <br /> Asphalt pavement thickness required = 0.95/2.32 = .41 <br /> (Two layers required C 0.21 and 0.20) <br /> Designers of pavement sections using this impacted soil should <br /> take under consideration the wearing surface of this asphalt <br /> material . Under high traffic conditions a bituminous seal coat <br /> wearing surface should be applied for best results.. Under light . <br /> traffic conditions a bituminous fog seal should be applied after <br /> the pavement is fully cured. <br /> USE OF IMPACTED SOIL AND ASPHALT MIXTURES AS TREATED BASES <br /> Under high Traffic Index conditions (TI greater than 6.0) it is <br /> recommended that this mixture be used as an asphalt treated base <br /> material with 0.33' depth of hot asphalt surface. This mixture <br /> may reduce the base requirement by 60% compared to standard Class <br /> 2 untreaded base rock. <br /> - ------- ----- ----._ - — METHODS - - <br /> Cold mixed asphalt pavements are specified by numerous public <br /> agencies.
