DROP-OFF CONDITION NOTES <br />1. These conditions and treatments can be applied only in work areas that fall within <br />a properly signed work zone. <br />2. When drop-offs occur within the clear zone due to construction or maintenance <br />activities, protection devices are required (See Table 8). A drop-off is defined <br />as a drop in elevation, parallel to the adjacent travel lanes, greater than 3" with <br />slope (A:B) steeper than 1:4. In superelevated sections, the algebraic difference in <br />slopes should not exceed 0.25 (See Drop-off Condition Detail). <br />3. Drop-offs may be mitigated by placement of slopes with optional base material per <br />Specifications Section 285. Slopes shallower than 1:4 may be required to avoid <br />algebraic difference in slopes greater than 0.25. Include the cost for the placement <br />and removal of the material in Maintenance of Traffic, LS. Use of this treatment in <br />lieu of a temporary barrier is not eligible for CSIP consideration. Conduct daily <br />inspections for deficiencies related to erosion, excessive slopes, rutting or other <br />adverse conditions. Repair any deficiencies immediately. <br />4. For Setback Distance, refer to the Index or Approved Products List (APL) drawing of <br />the selected barrier. <br />5. For Conditions 7 and 3 provided in Table 8, any drop-off condition that is created <br />and restored within the same work period will not be subject to use of temporary <br />barriers; however, channelizing devices will be required. <br />6. When permanent curb heights are >_ 6", no channelizing device will be required.

This treatment applies to resurfacing or milling operations between adjacent <br />travel lanes. <br />2. Whenever there is a difference in elevation between adjacent travel lanes, the <br />W8-11 sign with "UNEVEN LANES" is required at intervals of �5 mile maximum. <br />3. If D is 1 tle or less, no treatment is required. <br />4. Treatment allowed only when D is 3" or less. <br />5. If the slope is steeper than 1:4 (not to be steeper than 1:1), the R4-1 and <br />MOT -1-06 signs shall be used as a supplement to the W8-11; this condition <br />should never exceed 3 miles in length. <br />Travel Lane Travel Lane <br />Travel Lane Travel Lane <br />1 6" Solid Lane Line <br />ItIt` K (When Steeper Than 1:4) <br />h f 4 1 <br />1 I <br />TRAVEL LANE TREATMENT FOR <br />MILLING OR RESURFACING DETAIL <br />PEDESTRIAN WAY DROP-OFF CONDITION NOTES <br />1.
