The paper describes new developments of mixed-in-place stabilization of (sub-) base courses with cement. This method can be used in road and highway engineering as well as for airport runways. Essential are the mixing capacity of the site equipment, a precise scheduling, and proper suitability and acceptance tests. The minimizing of reflective cracking can be achieved by several methods, whereby micro-crack rolling of the fresh stabilization has proved very effective. This relaxation rolling can be optimized by means of continuous compaction control (CCC). Furthermore, CCC provides complete quality assurance - contrary to conventional random spot checking. The paper also reports on combined stabilizations: cement plus bitumen to minimize reflective cracking and lime plus cement for cohesive soils.read more

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.

Compaction- and strength properties of stabilised and unstabilised fine-grained tills
TL;DR: In this article, the compaction and strength properties of tills, both untreated and treated with stabilising agents, were investigated in both laboratory investigations and field studies, based on 13 different soils.
Effectiveness of minimizing reflective cracking in cement-treated bases by microcracking
Stephen Sebesta,Tom Scullion +1 more
TL;DR: In this article, the authors evaluated the effectiveness of microcracking for reducing shrinkage cracking in CTB by applying several vibratory roller passes to the CTB at short curing stage to create a fine network of cracks.
Soil stabilization field trial
TL;DR: A five-year study was initiated seeking materials/additives and procedures that help to mitigate crack susceptibility in cement-treated material (CTM), and a field test program of six 305m (1000ft) test sections was implemented in August 2000.
Pavement Recycling: Literature Review on Shrinkage Crack Mitigation in Cement-Stabilized Pavement Layers
TL;DR: In this paper, the authors investigated the use of hybrid stabilizers (cement with small amounts of asphalt emulsion, foamed asphalt, or synthetic polymer emulsions) to further limit the severity of shrinkage cracks on projects that include cement-treated layers.
