Black is the new "Green"! Porous asphalt is pervious asphalt that allows water to penetrate into an underground storm water management facility. This will allow the water to perk into the ground naturally.
Gray & Son, Inc and Maryland Paving, Inc. installed a porous asphalt section into their parking lot at the corporate office. This video takes you through the entire process for installing this storm water management system. From excavation, installation of aggregate and porous asphalt to a demo on the final product, this video takes you step by step. We even take you to one of our Maryland Paving Asphalt Plants to show you how asphalt is made. Please visit our websites for more information. www.graynson.com and www.marylandpaving.com

Lol, you can't just dump a layer. Fines are important for compaction. The purpose of fines is to reduce settlement. Your top layer will experience fine transport over time and your entire surface layer will drop. The design life of pavement will be considerably less. I understand you want to encourage ground water recharge, so how about you pick strips in the car park in which vehicles are not to run on. Slope you asphalt to these points and utilize your technology there. A good area is between back to back parking, use the concrete parking berm to protect the strip from traffic. You can have several strips of these, encourage the ground water recharge and get the design life. Also one should take into consideration scheduled cleaning of the surface course. Overtime, fines will clog anything

I watched these videos, starting with a locally made video from Dubuque, Iowa. The house I'm buying is in the Green Alley area. That means the alley will eventually be reconstructed with the permeable system. I think the cost is necessary, and I just got a feeling that this is where its heading everywhere. If I owned a paving co, I'd get my money into this.

all looks great, I am just wondering, in the event of a motor vehicle accident or accidental spill of what ever oil, pest-o -side how do you stop it running through and off into the ground and eventually the drains, as it is now not possible to dam the run off at the drain grate, as most car parks generally have oil patches where cars park and they usually are easily seen, dose this waste oil stain the porous asphalt or just soak through to the sub-straight leaving no visibly trace?

Interesting. Thanks for helping me get a better understanding of this. Some folks are apparently very much against the material, citing a litany of claims, but it's use is recommended and indeed sometimes required by NJDEP for sites that create large amounts of impervious areas. Could you guys elaborate a bit on appropriate locations for the material as well as recommended maintenance activities to ensure full life expectancy? My understanding is that locations seeing light traffic and minimal turning movements are ideal (i.e. satellite parking lots) and that vacuum truck cleaning is preferred over just basic sweeping. Can you confirm? Thanks!

It has several purposes: No water on the road. (Aquaplaning, better visibility) More water can penetrate into the soil underneath. Thus less water in the drainage system. Less water at once into drainage, it stores it. Less noise from trucks and cars. Every highway in the Netherlands has a surface of ZOAB (Zeer Open Asfalt Beton) Very Open Asphalt Concrete.

@stanleyjones2085 7 жыл бұрын

never stop fighting, LMAO, moving water doesn't freeze. I live in Iowa and the Mississippi river freezes every year. When water freezes it will expand in every direction by 10 percent its liquid mass. It would depend on how porous this new asphalt is. But then again in the northern states where we live the ice will just build up and it will destroy this material. Guess that's why it isn't really being used. I would have to say in the southern states this would cause the storm sewers to overflow more quickly because the water seeps into the material at a rapid rate not allowing the sun to evaporate it as much as it would normally. I guess to be sure about this one would have to do a study on this material and I for one do not think its worth the effort!

Seems to me that this type of asphalt would last longer. Regular asphalt only lasts 15 to 20 years in part because of standing water. If this allows the water to move through and out, that process should allow the asphalt to dry faster and last longer.

Wrong!! Tested by the University of New Hampshire for exactly what you are talking about and it reduced the need for deicing agents by up to 75%. The water goes down into the rock bed and does not affect the pavement. It has been used at a park in Massachusetts since 1977. See this link: www.millermicro.com/porpave.html. Walden Pond State Reservation One good porous pavement installation was installed by the Commonwealth of Massachusetts at Walden Pond as a demonstration project in 1977. Twenty years later, a long time for one paving job on that busy parking lot, it still looks good and works well.

@cdmichaelb 3 жыл бұрын

Freeze thaw cycles are fine. It's a porous material. The reason freeze-thaw damages things like concrete and cement when they get cracks is because more water builds up in there than escape, so as it freezes it expands and breaks. Porous most of, if not all of the water drains out of the cement/concrete. What doesn't isn't substantial enough to build up enough pressure to cause breaks.
