When barrier end is inside the established clear zone, attenuator service Type 1 or Type II shall be used. Refer to L&D special design drawings. 7. Barrier transition slope ratio shall be as follows: 65 mph-12:1 60 mph =:1 45 mph-16:1 :l 35 ►nph =13:1 30 milli =10:1 65 mph =20:1 SS mph =1 7:1 45 mph =14 ;1 331nph =1]:l When the barrier transition slope is an a horizontal alignment, the total offset shall be prorated around the curve in lieu of a straight -line stops. 8. Barrier vertical panels 8 inches in width and 12 inches in height shall be placed on top of the concrete barrier and spaced 96' on centers along the parallel or tangent sections and 48' on centers along the transition or taper sections. Reflectorized surface shall be fluorescent orange prismatic lens sheeting. The light at the breakpoint where the taper ends and the barrier becomes parallel to the roadway shall be a Type A flashing light. Barrier delineators shall be installed along the traffic side of the concrete barrier in accordance with Section 702 of VDOT's Road and Bridge Specifications. Guidance: 9.
