Characterization of Cementitiously Stabilized Layers for Use in Pavement Design and Analysis
TL;DR: In this article, the characterization of cementitiously stabilized layers and the properties that influence pavement performance are discussed, as well as performance-related procedures for characterizing these layers and performance-prediction models for incorporation into the mechanistic-empirical pavement analysis methods.
Kiln Dust for Stabilization of Pavement Base and Subgrade Materials
TL;DR: The use of kiln dusts to stabilize base mixtures is a mature technology as mentioned in this paper and has been used for slope stabilization, drainage from mines, among other things (Miller et al., 1997), however, according to Collins and Ciesielski (1994), Kiln dust was not included in any state highway agency (SHA) specifications in 1994.

Freeze-Thaw Durability of Subgrades Stabilized with Recycled Materials
TL;DR: In this article, an extensive laboratory study is underway to characterize the freeze-thaw durability of laboratory soil samples stabilized with CKD, LKD, FA, and CFs.
Influence of subgrade condition on rutting in flexible pavements- an experimental investigation
TL;DR: In this article, an attempt is made to investigate the influence of subgrade condition on the rutting phenomena in flexible pavements, where flexible pavement section is formed in a steel box section with a standard pavement section over a clayey subgrade.

Pavement Subgrade Stabilization Using Recycled Materials
Abstract: The performance of subgrade stabilization with cement, lime or lime/fly ash are extensively studied. However, the use of recycled materials for subgrade stabilization is yet to be properly studied. If proper mix designs and construction specifications for subgrade stabilization with recycled materials are available, those materials can be used for pavement construction. Recycled materials not only provide cheaper alternatives for subgrade stabilization, they also alleviate landfill problems. Most of the previous studies were related to subgrade modification with recycled materials, limited to quantify immediate benefit through construction facilitation. However, there is a need to identify the long-term benefits and/or associated risks to use recycled material for subgrade stabilization. With satisfactory long-term benefits, subgrade stabilization can be potentially used for optimizing pavement designs that will result in cost effective pavement sections. If this study reveals any long-term risks associated with subgrade stabilization, those will be addressed by either remedial actions or by limiting usage of those stabilizing materials. This paper examines the preliminary results of a laboratory testing program to determine benefits and risks of using recycled materials such as Cement Kiln Dust (CKD), Lime Kiln Dust (LKD), Fly Ash (FA) and Concrete Fines (CF) for subgrade modification as well as stabilization.
