The methods used in ancient times to work with local soil in the construction of roads were empirical, and like other craft activities, were passed from generation to generation.
The information available today in this field is based primarily on science-based systematic studies corroborated by experiment, extraction of geotechnical data and good practice in the application.
However, technology is always a few steps ahead of the reality of the applications in road construction or road bases and clearly in the field of stabilization copolymers, at least in our country it brings us an advantage over 25 years of use compared to other countries with stringent quality systems like the US, where insurers and government agencies do not allow doubts regarding the quality and effectiveness of the methods or products used in building roads.
In general, all soils can be stabilized, what happens is that if the ideal stabilization is to be achieved with contributions from other soils (improved particle size) or by means of other elements (cement, lime, sodium chloride, etc. ) the cost of the improvement may be too high if the ground is correct does not meet certain conditions of internal structure.
