Abstract:
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. Reclaimed asphalt pavement (RAP) was mixed with 3, 7, 11 and 15% fly ash and the laboratory samples were evaluated for fatigue life, durability, freeze-thaw resistance and thermal cracking. The performance of RAP mixed with asphalt emulsion and asphalt emulsion plus hydrated lime was also evaluated.
