Diagnose the failure before you patch
Not every void is the same repair. A surface ravel needs a fine-grade cold-mix; a deep pothole through to the base course needs structural fill. A crack network is a crack-filler job before it becomes a pothole. Diagnose first, then select.
Quick checklist: is it a crack or a void? If a void, what depth? Is the base sound or pumping fines? What traffic class? That decides whether you reach for 5, 7, 10, 14 Gauge or rubberised crack filler.
