The minimum 28 -day compressive strength for PCC shall be 3300 psi for shared use paths. No vehicles, including construction equipment, shall be permitted to use the pavement until it has reached its full design strength. No exception will be given to allow use of PCC shared use paths prior to reaching design strength. The minimum pavement thickness shall be determined by the pavement design analysis but in no case shall be less than 7 inches. All joints within shared use paths shall be saw cut. Transverse contraction joints shall be spaced at relatively equal spacing between joints and shall be close to the same spacing as the longitudinal joints so that the panels are relatively square. Spacing between transverse joints shall not exceed 15 feet for PCC that is 7 inches or more in thickness. The length to width ratio for any panel shall be at least 0.75 and shall not exceed 1.25. Joint reinforcement is not required for shared use paths except as required by the pavement design. The minimum aggregate base thickness shall be determined by the pavement design analyses but not less than 2 inches of compacted 3/4 inch -minus crushed rock shall be placed before the concrete pavement is poured. (See Appendix E for Shared use Path Standard Detail) 2.03 SIDEWALKS Sidewalks shall provide an unobstructed, continuous and safe path for pedestrians and be designed in accordance with the City's Design Standards and Guidelines for Streets, Sidewalks, Bikeways, and Accessways (provided in Appendix E and on the internet at www.eugene- or.gov), ADA requirements, the Standard Specifications and Drawings, and the following: A. Access Ramps Each access ramp and its associated wings, landing and other appurtenances shall be included in the plans and shall comply with the 2011 Proposed Accessibility Guidelines for Pedestrian Facilities in the Public Right -of -Way as published by the United States Access Board (located on the internet at www.access-boardaa). All clear width measurement shall be exclusive of the curb. At new intersections, access ramps shall be constructed in the projection of all crosswalks as defined by the Oregon Vehicle Code. Receiving ramps shall be constructed on the opposing side of newly established intersections. A design exception, per Section 1.04, may be authorized in retrofit situation where a crossing is impractical due to Public Improvement Design Standards Manual, 2016 Page 2-6
