Hello, could you tell me the model of the cold planer at 1:30 min? It's cool that it has its own asphalt container. EDIT: Nevermind, that's a separate dump truck. Model of the truck then?

This is certainly not how rolling is done here, after the initial pinch you should run your drum more then half way over the new mat to seal the joint as this pass will push the material back which was pushed away when pinching the joint, pinching an overlapped joint will basically result in the same results with busted aggregates but like demonstrated in this video it’s for durability not LOOKS!

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?
@MarshallKlinefelter2 жыл бұрын
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

@MarshallKlinefelter2 жыл бұрын
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.

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...
@MarshallKlinefelter2 жыл бұрын
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.

Do a roadtec course, it's a similar method to what they recommend. You shouldn't pinch a join more that a half drum of a roller. Basically what you have done is push the material out of the join. It might look mickey mouse, if you pinch, but if your goal is joint compaction, that's how you achieve it.

I have uploaded a brochure for you.: drive.google.com/file/d/1EmUG3FVg3pEVz_ED9qa7O8X7a0L3c2gG/view?usp=sharing 504.03.08 Joints. Construct joints as directed and as follows: (a) Stagger longitudinal and transverse joints in successive courses so that one is not directly above the other. (b) Stagger transverse joints by the length of the paver. (c) Stagger longitudinal joints at least 6 in. and arrange so that the longitudinal joint in the top course is within 6 in. of the line dividing the traffic lanes. (d) Construct joints in a manner that provides a continuous bond between the old and new surfaces. (e) Overlap the existing pavement 1 in. to 1.5 in. when constructing longitudinal joints adjacent to existing asphalt pavements. (f) The initial longitudinal roller pass shall be on the uncompacted hot mat and 6 in. to 1 ft from the joint. The successive roller pass shall compact the overlapped material and the 6 in. to 1 ft material simultaneously. (g) Apply tack coat to joints as directed. Cut back the edge of the existing pavement for its full depth at transverse joints when placing a surface course, and apply tack coat material as directed. (h) Apply tack coat to all contact surfaces before placing the mix against curbs, gutters, headers, manholes, etc.

If you see white at the joint, that is material being pulverized from vibratory roller crushing aggregate that is over on existing cold mat, joint on first pass should be pinched in with most of the drum on the existing mat, then half drum with vibes on, breaking the mat down from the high side down, compacting when mat temp falls below 240 degrees F and finishing from the low side up when temp falls below 170 degrees F. Porous asphalt is not to be vibed static roll only usually with a max of 5 passes and be finished before temp hits 145 degrees F. then there's warm asphalt, total pain in the ass.

@@ks5739 Well whenever possible it's ideal to close at least of highway and run staggered pavers all hot lapped it is like one paver pass edge of shoulder to edge of shoulder. but when you cant like you said, last pass down the middle allows rakers and rollers to rake and roll cold joint, pushing traffic out on both outside lanes giving you enough room to do your job. Plus whether it's an invert or crown? the lanes are paved staggered from where those lanes will be striped you dont want the track line of vehicles running down the lane joints will unravel in a short time. Kyle what state are you in? and you do mostly commercial and industrial paving?

Agreed, that white is smashed aggregate so you no longer have 100% bitumen coverage on your aggregate and you have created a finer gradation.... two specs that have always been deemed critical design. Better solution is use a joint heater. Operating cost less than 10 cents per foot as per contractors.
@AnarchyEnsues Жыл бұрын
If you pinch the join first, you have basically pushed the mix that needs to be in the join out. You can pinch the join later if required. I always pave a stone width over the join,. The crushed stone has shown in studies to provide better join and pavement life. It's less likely to absorb water as a open join, under compacted join, that can happen from pinching.

How are you re-compacting the cold edge that is 4-6% less compacted as per AI? FAA says to cut off this edge, What density do you get on the cold edge by this method? The white line is just smashed aggregate that is not covered with bitumen. We supply a joint heater that allows you to re-heat and re-compact the cold edge, the cheapest way to get recompacted density on the cold edge
@dennisbrown65024 жыл бұрын
if its a cold joint? rolling 6 inches away will in most cases push mix over onto to cold mat, depending on factors, depth, vibrating, and tonnage of breakdown roller, i have seen most times if it does not pushes mix over joint, it will leave a drum edge line that wont roll out it will fold over, now are first breakdown rollers are pneumatic or rubber tire and rolled 6 inches from cold joint works perfectly.

Yes, Guillermo, they were using a Troxler 4640-B Surface Thin Layer Density Gauge for QC monitoring. The density acceptance parameters use only cores taken from the final roadway and maximum specific gravities from behind the paver samples. Looking at data from SMA jobs across MD, the average is in the 95+ % of MSG.

Hello Marshall, great video. Question is regarding drain - down. I'm not sure of what your state requirements are for SMA mix design; just wondering how the results of drain - down for fiber less SMA compares with conventional SMA. Did you have to modify your mix design to include more screenings to meet volumetric properties? Thanks in advance.
@MarshallKlinefelter9 жыл бұрын
The state requirements are not different for SMA based upon production methods. The same criteria apply: MIX TOLERANCES PHYSICAL PROPERTIES VCA* Mix, % Less than VCAdrc VMA, % 18.0 min. VTM, % 3.5 Ndesign Gyrations 100 Draindown, % max 0.3 Stabilizer, by weight of total mix, % 0.2 - 0.4 *VCA - voids in coarse aggregate. The mix was not modified other than fibers were not used, Evotherm M1 was used and the production temperatures were reduced to approximately 285°F.
