This set of photos presents crack & seat and asphalt overlay of airport pavements. Antigo has cracked airport concrete up to 18 inches thick. Note how wet pavement shows the cracking pattern.
Crack and Seating Done Without Removing Asphalt Surface on Runway Rehab Project
When culling old documents from file cabinets, one sometimes discovers reminders of past accomplishments that bring back good memories. Antigo Construction performed crack & seat of Runway 5/23 at Columbus Airport (IN) in 1988. The project was unique in that the 8-inch-thick concrete pavement was cracked and seated without first removing the existing 6-inch- to 2-inch-thick asphalt overlay. Nondestructive tests (now known as falling weight deflectometer) were performed to measure the elastic moduli of the concrete layer before and after cracking and seating. The testing confirmed effective cracking and seating of the concrete layer. This article from 37 years ago reminds us that though much has changed in the construction of pavements, the basic concepts of fracturing concrete pavements prior to an asphalt overlay still apply today.

The use of crack and seat treatment in refurbishment of airfield pavements
The overall purpose of the guide is to provide enough information to enable those engineers not familiar with crack and seat technology to be able to conduct effective maintenance of concrete pavements at airfields.
