Section 816.152 (d) Continued. <br />• tt~e design to such factors as the foundation, geological structure, <br />soils, type of construction and equipment to be used. A structural and <br />foundation analysis shall be performed to establish design standards for <br />embankment stability appropriate to the site. Publications of the <br />American Association of State Y.ighway and Traffic Officers (AASHTO), <br />including AASHTO T-99, T-160, T-9i, ar~d tie modified AASHTO test, or <br />other specifications generally recognized by transportation engineers as <br />adequate for design of riighway embankments, shall be used to determine <br />the degree of compaction required, on th=_ basis of soil type and the <br />anticipated volume of traffic and weight and speed vehicles to be used. <br />Compaction effort shall be adequate to achieve the degree of compaction <br />required. iJo lift shall be placed on a layer until the design density <br />is achieved throughout the layer. PASHTO specifications such as T-99, <br />T-180, the modified AP.SHTO test, or other comparable specifications <br />approved by the regulatory authority shall be used as guidelines for the <br />determination of the maximum dry density for granular materials. <br />• (7) material shall be placed in an embankment only when its moisture <br />content is within acceptable levels to achieve design compaction. <br />(8) Embankment slcpes shall not be steeper than lv:2h, except that <br />where the embankment material is a minimum of 85 percent rock, slopes <br />shall not be steeper than 1v:1.35h if it has been demonstrated to the <br />regulatery authority that embankment stability will result. Where rock <br />embankments are constructed, the}~ shall meet the requirements of Paragraph <br />(d)(u) of this Section. <br />(9) The minimum safety factor for all ericankments shill be 1.25, or <br />such higher factor as the regulatory authority ma specify. <br />(10) The road surface shall be sloped toward the ditch line at a minimum <br />rate of one-quarter inch per foot of surface width as measured from the <br />centerline of the road. <br />• <br />816-182 <br />
