They have more volumes of information on mix designs and procedures than anyone.
Pay attention to aggregate shape/type (rounded, angular or crushed), since in many cases it can be the major factor. - It has to do with interlock (mechanical strength) in addition to cement requirements (bonding, etc.).

As you could gather from my previous post, I know nothing about pervious pavements. But pavements in general work best when water is kept out. Defects in the surface lead to water infiltration and potholes. So if the intent is to let water in, a different type of pavement structure below the wearing course will have to be used. Your problem may not be the mix design, but rather what is under the top layer.

Also, keep in mind that pervious pavement ultimately becomes less pervious as the voids fill with debris. Some will tell you they are "self flushing". They're not. Minor flushing occurs at the surface, but below that no flushing occurs. If you are using it as part of your stormwater runoff system, consider that the runoff coefficient will be greater than gravel, but less than asphalt, at least initially.

As far as I know, the pervious pavements in current use are not appropriate for vehicular traffic.
I went to an FCPA (Florida Concrete and Products Association) seminar recently and the presenters said that pervious rigid pavement should not be used in trafficked areas.
They can be used in parking lots, but even then the aggregate will debond over time if the parking space is used frequently.
I assume you are talking about rigid pavement.
Pervious asphaltic pavement (open graded mixes) have the same problem in that there is not enough cement to properly hold the aggregate in place.
I also agree with the above statements that the pores will clog over time if not cleaned regularly.

Pervious Pavement for Roads Has been the Dream of most
environmentalist. The idea of a Reservoir under the pavement
seems enticing but sadly though no one has come up with a cheaper solution in the maintenance of your sublayers cause definitely they need yearly cleaning or replacement.
If your state is encouraging pervious pavement why used mixed design why not used Bricks their more structurally sound,durable and easier to remove for your sub
layer maintenance although significantly more expensive.
There are so many specialist in pervious surface now a days
like Unilock but mostly though theyre only doing it on parking lots and alleys.
Check them out and asked for the mixed ur asking (Unilock)

Curious about alternatives for driveways that wouldn't count as hardscape.

They have good inhouse case study data about pavement performance: pavers, pervious asphalt & concrete. Sorry I don't have a contact from their presentation at AWPA last spring. They would be my recommended starting point for any northern climate design.
