Road repair should address the cause of failure, not just cover the visible pothole. Rutting, washboarding, edge loss, soft spots, washouts, and standing water may result from failed drainage, weak subgrade, inadequate base, traffic loads, or lost surface material. Start by mapping damaged sections, culverts, ditches, crowns, outlets, slopes, and delivery access. The repair may involve reshaping, undercutting, adding suitable base, stabilizing soft areas, replacing surface aggregate, compacting lifts, or protecting drainage outlets. For an estimate, provide road length and width, photos after rain, expected vehicle types, known base material, problem locations, culvert condition, access constraints, and the finish and maintenance standard required.
Frequently Asked Questions
Why do potholes return after filling?
They often return when trapped water, weak subgrade, poor compaction, inadequate crown, or failing base material is not corrected.
What should a road-repair assessment include?
Inspect drainage, crown and cross-slope, base condition, soft spots, culverts, shoulders, traffic loads, material depth, and outlets.
What should the proposal distinguish?
Separate grading, undercut, stabilization, imported material, spreading, compaction, culvert or ditch work, finish, and cleanup.
