Interesting links and information on construction methods:

Pavement Savers Inc., brick street restoration company that uses radiant heating technology - http://www.smoothroad...

Netherlands - street brick laying article and videos featuring Tiger-Stone equipment

From a Tiger-Stone representative, http://www.tiger-ston...

"In the Netherlands we use 15 inches of concrete debris ( pulverised concrete) and on top 2 to 6 inches of sand ( of good quality, not like the sand on a beach…) In a lot of countries the use stabilized sand, this is a mixture with cement. The most important is that the base construction is solid so in the long term the road quality can be guarantied. We use sand on the last few inches because the ‘’old’’ stones are not likely to al have the same dimensions. The sand does have the compacted with a compacting plate before paving the stones."

From Davenport, Iowa:

"We generally use six inches of 95% proctor compacted ¾” down (with fines) crushed stone material for the base, with about 1” of sand on top of that. We vibrate the bricks into the sand, then sweep more sand over the top and vibrate again to get the sand to fill the gaps between the bricks. On hills we mix in 1 part mortar to 3 parts sand to prevent the sand mixture from washing away."

From Willmette, Illinois:

"This work shall consist of removing existing bricks in streets at various locations determined by the ENGINNER; removal of the existing deteriorated stone base to a depth of 6 inches, placement of a new 6 inch CA 6 base (CA is crushed aggregate), a 1 inch sand layer and replacement of the bricks."
