The present thesis showed the advantages obtained from stabilizing the soil between Calamarca and Huaso with PROES additive and Portland cement in order to use it as an improved subgrade for the pavement. One of them is to increase the soils support capacity and the other one is to demonstrate that the use of both additives allows to reduce the costs of construction compared to a traditional pavement structure. This study is of the pure experimental kind, because the dosage of the PROES additive was manipulated until the optimal percentage was achieved in order to get the maximum CBR. The methodology was based in traffic study, soil mechanics studies, special tests like CBR and Modified Proctor Compaction Test, and pavement design using the AASHTO 93 method. With this data, the pavement design was elaborated with and without the use of PROES additive and Portland cement in order to verify its convenience in terms of costs. For data collection, the technique used was observation and the instrument was the observation guide, to define the main problems that affect the road. The CBR test was performed in three sections between Calamarca – Huaso and it was determined that with the addition of 0.27 L/m3 of PROES liquid additive and 45 Kg/m3 of Portland cement, the CBR of the three samples evaluated increased from 6.90% to 109.80%, from 7.57% to 116.40% and from 7.54% to 114.28%, increasing by more than fifteen times the CBR of the natural soil. At the same time, the costs per Kilometer of pavement with and without PROES additive and Potland cement were compared. The pavement with both additives has a cost of S/ 368,487.90 per Km and the pavement without additives costs S/ 436,465.92 per Km, which is 18.45% more expensive than the first one. Also, it was demonstrated that the execution time of the pavement with additives decreases by 30.77% with respect to one without additives. The investigation concludes that there is technical and economic feasibility for the construction of pavements using PROES additive and Portland cement as soil stabilizers.
