Table A-. Maintenance and Rehabilitation Strategy
Maintenance Plan Summary
Transverse Joint Sealing Seal 50% of transverse joints every 20 years.
Longitudinal Joint Sealing Seal 50% of longitudinal joints every 20 years.
Transverse Crack Sealing Seal 100% of transverse cracks every 20 years.
Localized Rehabilitation Plan Summary
1. If lot average percent cracked slabs exceeds 10.00%, then apply full slab replacements to 100% of cracked slabs.
2. If lot average percent spalled joints exceeds 10.00%, then apply partial-depth repairs to 100% of spalled joints.
3. If cumulative percent cracked slabs exceeds 15.00%, then consider the sublot failed.
4. If cumulative percent spalled joints exceeds 30.00%, then consider the sublot failed.
5. If average transverse joint faulting exceeds 0.1000 in., then consider the sublot failed.
6. If IRI exceeds 150 in/mi, then consider the sublot failed.
7. If percent failed sublots exceeds 25%, then begin global rehab scenario 1 and STOP for this year.
Global Rehabilitation Summary
Prior to First Phase Repair 100% of outstanding spalled joints with partial-depth repairs. Repair 100% of outstanding cracked slabs with full slab replacements.
Phase1 Diamond Grinding; Assumed Life; 10 years; Starting IRI: 60in/mi; Ending IRI: 150 in/mi.
Phase 2 AC Overlay; Assumed Life: 10 years; Starting IRI: 60in/mi; Ending IRI: 150 in/mi.
Phase 3 AC Overlay; Assumed Life: 10 years; Starting IRI: 60 in/mi: Ending IRI: 150 in/mi.
Phase 4 AC Overlay; Assumed Life: 10 years; Starting IRI: 60 in/mi; Ending IRI: 150 in/mi.
