Kansas has many miles of thermally cracked roads primarily in the western one-half of the State. Rehabilitation with conventional hot mix asphalt overlays and hot recycling have not given the service life expected before the existing cracks reflect through the pavement. Since 1986, the Kansas Department of Transportation has been utilizing cold in-place recycling (CIR) with an emulsified asphalt as an additive as a cost effective alternative for rehabilitation of thermally cracked low volume pavements. Field performance of the final product appears to have more variation than desirable with an expected life of three to five years. The results of a two year study indicate that the material properties of the locally available aggregates are poor which results in low strength of the CIR mixes.
