I came here to do my driveway pothole & crack repairs. Consumer tack products are mainly sold in 5-gal containers, and it's hard to find but available from suppliers. Applying tack seems to increase the likelihood that DIY patches become "permanent' (meaning 10+ years), but it seems the patch material producers don't encourage it as they sell on "quick & easy", but not "once & done."
Tack truck driver of 5 years here. I originally operated out of Texas spraying multiple types of emulsions, but now that I operate out of Northern Georgia we spray asphalt cement typically applied at 375°Fahrenheit. All of the luxury of shifting, lowering, and lifting the bars at that temperature and with AC material becomes dangerous due to a history of o-seals rupturing either end of the drop tubes. Do you have any suggestions?
Greg, Spraying straight asphalt has many bonuses, but as you mentioned, some hazards. I foresee a day when the tack truck will be able to apply a void-reducing membrane on the longitudinal joint simultaneously with the tack on the remaining mainline. A single application temperature would be needed for a two-material system. The key to operating at those elevated temperatures is keeping the temperatures at the minimum needed to have the pumpability of your materials while not clogging your nozzles. Second is maintenance to your system including the nozzles. Keep them free flowing so we can keep the pressures at the minimum needed for proper application. Thank you for doing a great job and please be safe out there!!! -Marshall
Congratulations. This is a very important job that normally gets very little credit. Take pride in your work and help make a great road. Send me a picture of your work. MKlinefelter@MDAsphalt.org
Respected presentor, very informative video.One sugesstion though. Can you also include metric system when conversion as your viewers are from all over the globe.Kudos. Cheers!!!!
Hello Marshal, Do you see an issue applying tack coat one (1) day in advance due to cold temps? Assume zero traffic on the tack in this period as the road is closed...
Ryan, not at all as long as you can keep the tack clear of foreign debris. I have been on a job where we were required to tack in advance on an airport runway, and after the crews left, airport maintenance crews mowed a nearby field and tumble weeds covered the entire mat. It heavily delayed the paving operations while the surface was cleaned and retacked.
Good question... They were spraying at 50% of the typical rate so that we could clearly show the distinguishing features of the tack prior to breaking and setting. When they finished they had the unpaved areas properly coated at a rate on the high end of the specification.

@@MarshallKlinefelter youre awesome! Thanks for the response. Great video!
thank you for the information
.22 / .25 litres per square meter if anyone in Canada is wondering. We dont use gallons per square yard up here.
can you use this tack as a driveway sealant??
No, that is not recommended.
I want to be a tack truck driver. Any company in the chicago area looking for a CDL driver I am willing to learn the trade.
I hate the distributor
Well explained.
Well done.
Why is the driver overspraying so much?
