30. Transverse strains bottom of HMA

31. Strain in geotextiles

32.  Reinforced sections (sections F and H) performed better than the control in terms of rutting and pressure on subgrade.  Pressure and strains in the reinforced sections did not change much until about 100,000 wheels passes. After that, geotextiles was mobilized and these parameters changed considerably. Conclusions
