Evaluation of fly ash in cold in-place recycling. Final report, July 1994-April 1996

Technical Report ·
OSTI ID:418918
The Kansas Department of Transportation has developed an innovative method of rehabilitating pavements of low volume roads utilizing cold in-place recycling of the asphalt and mixing type C fly ash with the recycled material. Field test sections indicate fly ash improves constructability and moisture sensitivity as well as utilizing a by-product that currently ends up in landfills. The same field test sections have shown increased cracking with increased fly ash contents and a drop in pavement modulus with time. The results indicated that seven to eleven percent fly ash provided optimal laboratory freeze-thaw and moisture sensitivity performance. Increasing the fly ash content resulted in more brittle fatigue behavior as well as an for selecting the optimum fly ash content.
