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.
Evaluation of Concrete Slab Fracturing Techniques in Mitigating Reflective Cracking Through Asphalt Overlays
This report presents the results of an evaluation of concrete slab fracturing techniques as a means of arresting or retarding reflective cracking through asphalt overlays placed on severely distressed portland cement concrete pavement.
Life Cycle Assessment – I-5 Seattle
This paper compares three different replacement options for an aging portland cement concrete (PCC) pavement using LCA process-based protocol. Those options are: remove and replace with PCC pavement, remove and replace with hot mix asphalt (HMA) pavement, and crack-and-seat the existing pavement followed by a HMA overlay.
Layer Coefficient Values for Cracked and Seated Concrete
The WisDOT Bureau of Technical Services is interested in identifying layer coefficient values used by state DOTs nationwide for cracked and seated concrete, in comparison with values used for rubblized concrete.
Improved Design of Overlay Treatments
The objective of this research was to develop improved design guidance for asphalt overlays to concrete pavements by providing techniques that will reduce the thickness of overlay while still minimizing the occurrence of reflective cracking.
Reflection cracking on airfield pavements – a design guide for assessment, treatment selection and future minimization
This guide has been prepared for Defence Estates (UK) to provide guidance on the identification, categorization and treatment of reflection cracking in airfield pavement structures.
"Antigo Breakers Ltd during both the research & development project and also the first phase of the Crack & Seat reconstruction project has offered an excellent level of service. Their proactive approach, level of control and quality is excellent."

Practical Method of Ensuring the Success of Crack and Seat Operations Using FWD
This procedure has two phases: (a) determine the hammer parameters (height and spacing) that develop good cracking patterns, full depth cracks with adequate aggregate interlock between the cracked segments and (b) determine the optimum number of passes of a rubber-tired roller.
