This slurry is a blend of cement, water, some Class C ash, and an admixture that keeps the solids in suspension and prevents hydration from beginning until it is mixed. It is a very revolutionary way of soil reclamation, stabilizing, and treatment.
@00justSomeAccount00 not cheaper. It's often used in conjunction with soil tests; ie.. moisture water content or permeability. Soil stabilization is the reason for this. Your road is only as good as your sub base and base material. And, your sub base is only as good as the sub grade.
Amazed to see how easy one can build roads when you are in a warm and dry climate. Where I live motorways are constructed with a three meter thick drainage layer, to ensure the road isn't affected when the ground freezes in winter.
@@Kni0002 It is indeed, as a general rule of thumb the cost of constructing a standard four-lane motorway to these specifications is about EUR 25000/meter -- USD 9000/foot. But what can you do, in the past we have seen roads built to lower standards seriously deteriorated after the first winter. On smaller roads with lower speed limits the standards aren't quite as high, as you can tolerate a bit more uneven surface, but even there the drainage layer is between one and two meters.
Building it right the first time is cheaper. Having to rebuild the road every couple years is expensive and creates traffic flow problems. This video was shot in Kansas, and even though we dont get much rain in kansas, we deal with alot of freezing and thawing, so they really should have built foot or two thick drainage layer underneath. I always hate seeing asphalt laid directly instead of on concrete or a proper drainage bed.
Ok yesterday we went on a river trip in L.A. i told husband how amazed i am at mountains roads. How men and machinery is just amazing. Then I said 😂this looks like such a hard job for even men and machinery 50 or more yrs ago to make. I was maybe this is all an illusion and were all an illusion or maybe the aliens built this... Miles and miles of mountain roads just amaze me. He laughed! So here I am being amazed. Men and machines!! Are the greatest! I think too much while on road as passenger. Freeways, highways, bridges, tunnels and so much in world connecting is imazing.
That's quite interesting to see how other groups do road construction. I'm a finishing grader operator myself and we have never used a slurry in the base. The layout of your road heavily depends on your soil structure underneath. Where i am from within 30 years all of your gravel will be gone. The soil mixes up into the gravels and it turns straight to mud again. Core sampling proves it.
@@davidanalyst671 We use a base gravel, which locally we call 32 Base. It is a mixture of crushed rock and fines, as well as a binder, which is usually clay. One the gravel is down we tack oil the entire surface to be paved, it protects the surface from rain, and helps the asphalt bind to the gravel. In order to pave over the gravel we compact it for consecutive hours, usually 2 passes with a double steel roller. Once vibrating, and once static. Then we wet the gravel and hit it with a wobbly(multiple tire packer) for hours, adding water. We do this for every lift of gravel we put on as well. Last few projects I've done were 300mm of 32 base. It gets hard, so hard that a fully loaded semi doesn't even deflect it. You can do a literal burnout on the surface and it wont tear into the surface.
@@LLImprovement my dawg. you answered me without BSing me and calling me a communist!!! First person today. You should do a vid on this so I can see it. the only reason I asked was because this particular video looked like they dumped asphalt on dirt.
@@davidanalyst671 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-hjROssPcwX4.html Here's a playlist of a project I did years ago. Doesn't show everything as I was actively working on site. But it gives you a good idea of how we do it. This intersection was one of the busiest in our entire city so it was a rush job. But still to this day the road hasn't moved an inch. Usually the paths where the heavy trucks stop and drive are ruts. But 6 and a half years later its still good. That's what happens when we put as much slag and geotextile material down as we did. That was the only project we did in my time that was done properly and correctly. The rest have been skimped on.
sometimes renting is better, if you own it and you break something its all out of pocket. renting you can get a machine swapped out in a day or less and youll be running without the extra costs. they both have their place
whenever i see road crews it seems like they'll have their cones, tape and equipment all set up for weeks/months sitting idle until one day out of the blue they complete an entire stretch of highway in like two hours
I believe a majority of the work is planning, utility work, and surveying. Soil treatment and structure might take a while too when actual machines role out.
This road construction procedure is incredibly informative! It's fascinating to see the meticulous process behind creating such vital infrastructure. You might find it beneficial to explore the Buildovate CRM for assistance with managing construction projects similar to these!
Next year the County Highway Department will come in and chip and seal it and spray oil all over it to "preserve" it. It'll never look like this again.
I'm starting a job with a very high paying construction job soon with the possibility of moving up to second in command thanks to a buddy of mine, I'm doing research because I want to be ahead of everyone else I'm competing with.
because of inflation. if they do the job now, it costs 100,000, but if they do it in 5 years, that gets knocked down by inflation to 80,000 but they got paid today
6:29 those two should have seats that are placed in front of the sprayer at the same level, to allow them to see what's happening. Sitting up all day is not pleasant for anyone and two chairs, rerouted controls and the frame work costs little. Take care of your workers and they're always going to work better.
The roads I have seen built the contractor blades the road bed then Gravel of some type is trucked in and leveled, then the Asphalt is laid or the concrete for the finish. Is that dark liquid they sprayed on with the truck a Sealer of some type.?
The dark liquid is SuperSlurry a liquefied type II Portland cement. This is the ground stabilization. We directly inject it into the ground using our patented system which allows us to measure and evenly distribute the slurry. It is a much more efficient process.
Reflection will increase more heat as the uv rays comes direct from the ozone layers holes and the reflected rays does not go back it remains inside the ozone layer so we should stop pollution first 😕
Yeah man it’s basically cement powder and water. Then the machine we call the Muncher lowers it’s drum and drives along and mixes it. It’s like a big rotary hoe underneath. Then the grader grades and the roller rolls
I know Andale in Spanish means hurry up but the reason we have our name is that the family comes from the city of Andale Kansas. Quality is our number one concern always. Build it right and build it tough.
@@andaleconstruction5510 my respects to yuor family and work is very professionally done, I'm my self a heavy machinery operator in Chicago area, god bless
Great video,have learned new technique,the sub base soil stabilization using slurry. I want to know what is micro cracking,its use and what is the initial time setting of slurry.
The microcracking concept can be defined as the application of several vibratory roller passes to the cement treated base at a short curing stage, typically after one to three days, to create a fine network of thin cracks
What kind of material is in the slurry? Lime + water? I want to get into road building and but don't have a clue where to begin, Also do you guys use base rock(recycled concrete type base) as an underlayment?
É por essas e outras mais ... q meu sonho é morar na América do Norte com minha família ... sou motorista de carreta e operador de trator ... aqui no Brasil ... sem chance de um trabalho assim ...
