OT; Spray Patching Machine

Poor Farmer 830 · Dec 21, 2012

I work for the local township, and we are looking at getting a patch machine to salvage some of the roads we have without seal coating the whole road. Have any of you ever used any type of these machines. What are your thoughts. I live in central Illinois and not sure of any dealers nearby.

I have been around them. Four real things are needed for success, and they are realistic.

The pothole must be clean and dry with compacted un-disturbed earth (roadbase) in the bottom.

The temp must be warm enough to let the patch mix be compressed before it sets up. (ambient and mix temp are way important)

The pre-fill adherence tar must be used down to the roadbase, no being frugal.

The patch should be rolled or tamped to flush with the top of existing asphalt.

These are not necessarily in the book, but the process works very well on otherwise good pavement. It will not work on pavement that is already deteriorating bear the hole.

Leaving it above the surface causes the vehicles to bounce on it, and slam into the far side. Sure to fail.

Using a shop vac. or the like to clean loose material out is wise. Jim

Check out the DuraPatcher, made in Pearl, MS. I believe them to be one of the best. Just search them and you will find their website.

About 15 years ago we had a demonstration by a company who makes one. There are several companies that make them. This model was labor intensive as you needed a truck with the aggregate behind the machine to keep the hoper full. The stone must be dry.

The state has a private contractor that has a self contained unit, operated by one person. The driver of the patcher /truck pulls up to the pothole, swings out the remote controlled boom, blows out the hole, applies asphalt concrete,(tar). applies some more aggregate, more tar, until the hole is filled. No rolling or compaction. Seems to hold up fairly well, but I don't know if it would work in your case.

Poor farmer.. I have been in the equipment business for years and have seen all kinds of cold and hot patching apparatus. Some heat the tar and blow the rock together at the hole and several other methods. What I can say is I see a lot more for sale than I do being used. Several things I think, one it takes so much cleaning and maintance on the things that folks just decide there is a better way. Before I bought one I would want the selling company to give you three cities or counties that are using the unit and go check it out. A factory or sales man demonstration does not really give you real use experience.

personally, please pay careful attention to Janicholson's post. i rarely see or drive over a correctly repaired pot hole. before i go further let me state, i have never ever repaired a pot hole, however i feel i could correctly repair one that is safe and lasting. it cannot be that difficult just a crew that cares. that said please,for mine and others sake, tamp the mixture flush with the road surface.

I forgot to add that this machine is not a permanent fix but something that will keep things in better shape than what they are. This machine will be used on country roads that aren't the smoothest thing to begin with, and the size of farm equipment growing the roads were never designed to handle the weight.

Reading your post again, it sounds like you have more than pot holes? Rutting, alligatoring, etc.. If you have alot of problems with the outside 4-5 ft of a lane you could do what I did. I made a hopper/box 4ft wide on the end of the grade blade. It had shoes and was made to be 1.25 in lower than the grade blade. The trucks with the asphalt would dump out of the coal shute in the tailgate , spreading a 2 ft windrow. The grader operator would then come along and spread the asphalt 4 ft wide by 1.25 in thick. The trick is you have to have a grader that has blade float and articulates so the rear wheels don't run in the asphalt you just spread.

Chip Sealing a bad road will get you maybe 3 years, and does not make a road any smoother.

Check with the City of Macomb IL, they have had one for quite a while, I am sure they would tell you the good and the bad.

Hi
I am In Manitoba Canada. our highways Departments use one or more of the self contained units. The last 2 or so years they have been botching the number 10 Hwy south of Brandon with it.
Our gravel farm road is better than the c@#p black top they are trying to fix with it.
Im not gonna say i'm a road expert, but looks like a waist of time to me.
The gravels in the ditch 3 days after it's done,or stuck in your truck windshield by the car or semi coming the other way or the one you follow. water and frost still gets under it and heaves it all up for miles too.
Just a comment on what I see you need to make up your own minds on your application.
Regards Robert .

You don't say where you are in central Illinois but there are a couple companies that do a big bussiness spray patching roads. I am a Township road commissioner and have them every year to touch up soft spots from the spring thaw. It works great for a bridge approach that has settled. It stays put and doesn't peel out like the cold patch. Good luck.

I have done this work with a Dura Patcher, you are absolutely right, you must have everything perfect and you will have good results. You can do the same thing without the patcher using oil and 3/8 chips and layer it in a clean hole then covering with sand. Its not a permanant fix but at least the people are seing you are trying your best and they are not forgotten- that mean alot the the folks that try to look at things logicly.
