QUESTION PLEASE: * Out of curiosity, how much does "one" of those arches cost? Thanks Retired, Veteran
@DelawareT2Center2 ай бұрын
Thank you for your service. That is a good question, but we don't have the cost numbers on that project. Guessing...tens of thousands. And, of course, there is the prep work, the foundation keys, transportation, setting crew, and so on. There's a lot involved. But the advantages of precast sections like this in terms of quality control are a real leg up on traditional cast-in place.

@@DelawareT2Center Thanks for the nice complement, most appreciated. So you're best guess is that "one section" would be possibly $20k or $30k or ??? What would you recommend on how I could find out? Do you know who the manufacturer is? Any info would MOST helpful. Thanks! Mr Bowen Retired, Veteran

Excellent question. My recollection is that there had been significant rainfall on the scarified material prior to placement of cement and homogenization. But they still would have come back after grading it to wet it again and then it would be necessary to wet daily for 4-7 days, depending upon the design. That's all a weasel's way of saying, oops, failed to get a shot at a water truck! See this project as well - kzbin.info/www/bejne/qnm1dpKCgp5jas0 - there you see the water truck included.

Normally they are tensioned with clamps that are hooked into the eyelets where the lifting ropes were located. Since the individual elements have no seals between them, it appears to be a subordinate structure (culvert for a small river?). If they were ropes, the eyelets for the auxiliary ropes (which were needed for turning) would have to be located in the through-holes. But that would contradict the static requirements. Normalerweise werden sie mit Klammern verspannt die in die Ösen eingehängt werden an denen die Hebeseile sassen. Nachdem die einzelnen Elemente untereinander keine Dichtungen haben, scheint es sich um ein untergeordnetes Bauwerk zu handen (Durchlass für ein Flüsschen?). Wenn es Seile wären, müssten die Ösen für die Hilfsseile (die zum Drehen benötigt wurden) in durchgehenden Bohrungen sitzen. Das aber würde den statischen Erfordernissen widersprechen.

Yes. Unlike most other field testing methods, there is a fairly high bar to entry for this and not just because of money; there's regulatory issues, medical testing, security, etc. However, Troxler has now come out with a non-nuclear gauge and it will be interesting to see if testing agencies migrate, at least partially, to these over time. As expected, there remain some questions about accuracy under some conditions and I suspect that will improve over time. We'll see. Thanks for the input!

We are not experts on the mix side. I would reach out to Slurry Pavers - www.slurrypavers.com/ - they're out of Richmond, VA and did the work here. You can also look at the resources at ISSA - www.slurry.org/ - a great industry association. Their Slurry Systems Workshop is in Las Vegas in January and that's a great opportunity to learn from peers across the industry.

Would look better if you guys did the hand work first then do the straight pull with the variable spreader box after, to mask the ugly hand work joints. Burlaps give a really ugly finish especially when they get dirty. Would use a secondary rubber to make a nicer finish. You can get it the secondary addon at bergkemps. I noticed a leak behind the chute of the paver The 2 guys on the spreader box are way to clean, wich tell me they don't clean the box very often during the day. Manholes need to be covered with poly then taped at the bottom not with ducktape on top. At 8:57 the guy on the sled turned on the augers hydraulics while the other guy had his hand inside the box reaching for the lift chain ( very dangerous if the mixer did not turned off the augers.) Have a guy with a backpack blower in front of paver to removed leaves and debris. Hope you see this as constructive observations, you guys seem to have a good crew. Enjoy and pave on!

Could be. RoadResource.org is a great resource for looking at pavement preservation techniques and there you will see anywhere from 3-5 years up to 7-10 years, depending upon the nature and condition of the existing bed; and of, course, the quality of the materials and craftsmanship putting down the chip seal. There is a lot of science in the materials and there is a good deal of art and experience in putting it down. We have some roads locally that, with a double shot of chip seal and then slurry seal (some would call this a Cape Seal), have lasted 20 years with little distress; admittedly, low volume, low speed roads. You are also correct on the expectations side. Chip seal will reflect the existing surface profile, so if the existing road has some challenges (not too many or perhaps you shouldn't be chip sealing), some wedge and leveling with asphalt ahead of it may be needed. But well applied chip seal should hold up to snow plows reasonably, particularly if mold board skids are used to keep the cutting edge slightly elevated. Thanks for the comment!

@DelawareT2Center Жыл бұрын
Agreed. Best practice is to fully clean the crack. Spraying the weeds in advance can help the heat lance work even better, but there's not always the resources to do it. The better the crack is cleaned and dried, the better performance you can expect from the crack seal. But in practice, schedule, manpower, and the weather can complicate things and a good job of crack sealing is far better than letting those cracks erode your pavement.

@DelawareT2Center Жыл бұрын
I hope we have the translation correct. Seemed like you asked what was the goal or purpose. A good question. This road had become distressed beyond other pavement preservation methods (i.e., crack seal, microsurfacing) and had subsurface deficiencies. Simply milling and paving would have just put an expensive cover on a poor subbase. This techique re-homogenizes the existing asphalt and the drainage materials under it, mixes it with a small ration of cement and lots of water, creating a stronger foundation for a surface treatment. The result is a less expensive approach than removing all the material and replacing with virgin material. The road should be stable for many years to come and can be sustained with new surface treatment (probably chip seal followed by slurry seal) every 7-9 years. Merci pour la question.

Does this work & asphalt overlay
@DelawareT2Center Жыл бұрын
It certainly can be applied as a pavement preservation to asphalt in otherwise good condition (i.e., without advanced distresses). It does not provide additional structural strength; it seals out the surface to minimize water intrusion through minor cracks, stems the advance of oxidation and raveling, and can provide a little bit of skid resistance. More commonly (at least in our neck of the woods), it follows another treatment like chip seal. It is a low-cost treatment to extend the life of a pavement that has not deteriorated too far. Remember the central tenant of the pavement preservation toolbox - use the right technology for the right road at the right time. See also roadresource.org/.
