| Summary: | Using geosynthetic materials has noticeable effects on reducing the growth of reflective cracks in asphalt pavements. Meanwhile, some other parameters can be changed despite the positive effects and increasing the number of loads that the overlay can tolerate before cracking starts, and reducing the crack growth rate due to the reduction in shear strength between asphalt paving layers. One of the most important effects of changes in shear strength between pavement layers strengthened by geosynthetics is the change in resistance to other failures like rutting. In this study, the shear strength between the pavement layers was measured using the AUT-SFT device. Then, the resistance against rutting was tested for the same samples using a wheel-tracking machine. The results showed that the lower the shear strength of the geosynthetic reinforced specimens, the higher the rut depth in the AUT-SLT machine after the end of 600 load cycles. |
