In 2015, the pavement rehabilitation of the circuit of the University of the Americas Puebla (UDLAP) was carried out, which in almost all its extension required an overlayer because the structure was efficient, only the HMA was fatigued, however an area of 200 m. with large deformations where, since it is an archeological zone, it is not possible stabilize the natural terrain, the challenge then was to make a reinforcement that mitigates these deformations without stabilizing the foundation ground, in this work the details of the natural terrain problem will be discussed and the proposed solution that was implemented by reinforcing the subgrade with woven geotextiles.
