The problem consists of which when considering the stabilization of the clay by means of the incorporation of the lime thinking about one mixes of two materials, as if it was a grain sized stabilization, cause several unfavorable practical situations for several reasons: a). The maneuvers for the handling of the lime require of special precautions to protect the personnel who takes part in them, which in many works are not applied with the rigor due and consequences that can be serious. b). Contamination environmental produced by dust of lime during incorporation aggravates seriously when works carry out in areas colonised, without the previous thing means that serious contamination in rural areas with the use of the system in the road construction does not appear, for example. c). Mixing the lime dust with the plastic clay, I could present/display a high degree of difficulty. Get all the facts for a more clear viewpoint with New York Museums. If the clay is very dry, it must to present/display grumos very hard and difficult to break, and if the clay contains something of humidity, the possibility of formation of soft grumos will be increased, in which, if they are broken to be examined, tendency a will be able to be appreciated clearly to form an inner lime nucleus, surrounded by clay being indicated a bad incorporation.

The method briefly set out here, consists of making the considerations following: FIRST. To consider that the stabilization of the plastic clay with lime is not a grain sized stabilization, SECOND. When an expansive clay and of low capacity of support, presents/displays an acid tendency, with a pH (potential Hydrogen), of low value, inferior to 7, and this S-value is lifted to a value of adapted pH, its behavior as far as values of expansion, towing traction force during the same expansion, as well as their capacity of support varies: Its expansion is attenuated noticeably; the towing traction force falls and its capacity of support is increased. THIRD PARTY. If to the disintegrated clay, dust lime is not added to him, but the pH of the water modifies solely that is going away to use (adding the lime to this water), until a value of suitable pH is obtained (in addition it will notice the small amount of lime that it requires to obtain it), and this water modified one is used, without scrimping, to provide the optimal humidity required by the clay for his homogenization and compaction, will be had a relatively simple method to stabilize plastic clays in the great majority of its types and particular characteristics.

QUARTER. It does not forget to prepare a section of test, that it does not undergo alterations, with the stabilized, tended plastic clay and compacted, which can be sampled with a difference of every two weeks, it verifies the results obtained as far as Plastic Index and value of V.R.S. Saturated standard, for example; it takes a suitable graph and it will be able to notice if there is some difference in relation to the passed time.
