How to efficiently repair a 300' long asphalt driveway?
Should I use the asphalt crack repair in-a-tube or the loose stuff in a bucket for the cracks? It's a 50 year old driveway and the it's going to take a lot of whatever I use to fill the cracks. And I mean a lot, like 40 tubes.
There are some high and low spots on the parking pad. High spots: Will a belt sander (40 grit) even make a dent or should I use a special grinder blade in a 4" angle grinder (tedious), or what will grind down the aggregate in the asphalt? I don't want to rent a 50lb.commercial grinder that I can't physically use, due to its weight. Maybe take a torch to it and melt-out the tar, then how to remove the remaining high aggregate?
Patching the low spots seems straight forward - prep the surface, apply at the correct temperature, compact.
Do I have to use a power washer on everything, to get the slurry coat or top coat/sealer to stick or can I use a soap solution and the garden hose? I've a stiff deck brush on a long handle. How deep/wide of cracks will that slurry/top coat/sealer fill, 1/4"? With the high quotes I'm getting to have pros do it, I can afford to rent a power washer for two days.
