In Peru, the most important routes are terrestrial, among which, the most common are roadways, these present many deficiencies due to different factors related to errors in design, construction process and maintenance. Nowadays, in Lima, which has almost a third of the population of Peru, presents a large traffic volume, and this significantly affects the roads, especially in the South, where the pavement is highly exposed to sulfates and the natural subgrades have a relatively low bearing capacity. Considering this, in the south region of Lima appropriate constructions of concrete pavements are necessary, using the correct technology and with optimal materials, so they can provide a quality service with low maintenance. On the other hand, industrial processes should be applied to improve the quality and optimize the investment with efficiency. For all of this, the use of CRCP with pozzolanic cements is proposed. This research carried out the design of eight concrete mixtures with pozzolanic cements type HS and IPM, within which one of them was chosen to be applied as an alternative to improve the durability of rigid pavements in this zone. This design ensures a compressive strength of 310 kg / cm2, a rupture modulus of 35 kg / cm2, a water/cement ratio of less than 0.45 and a slump of 2½” in the workplace, which is ideal for a constructive process with a slip formed paving machine. To validate these main characteristics of the concrete, experiments took place in the laboratory for the concrete in fresh and hardened state. In addition, a cost – benefit analysis comparing different types of pavement (flexible, JPCP y CRCP) was made using the optimal mixture obtained in this research.
