| − | ==120.2.1 Paved Shoulder== | |
| − | | |
| − | ===Performance Expectation===
| |
| − | Paved shoulders shall drain water away from the mainline pavement, not be distorted or rutted, not have a drop-off/buildup greater than 0.5 in. and be free of vegetation. Any shoulder edge drop-off between 2-3 in. shall be a 1:1 slope and greater than 3 in. shall be a 1V:3H (3:1) slope.
| |
| − | | |
| − | ===Performance Measures===
| |
| − | Visual inspections will be conducted on randomly selected interchanges and tenth-mile segments in the fall to determine the percent of linear feet of both the inside and outside shoulder that look good and are performing as intended.
| |
| − | | |
| − | ===Performance Objectives===
| |
| − | 90% of the length of both shoulders shall be considered acceptable. Edge ruts shall be addressed according to the [[:Category:948 Incident Response Plan and Emergency Response Management|Incident Response Plan]].
