| The low cost, good initial strength, and high execution speed of roller-compacted concrete pavements make them an excellent alternative to conventional pavements in many road construction projects. This concrete can be made with recycled rubber granules instead of natural aggregates to preserve natural aggregate resources and contribute to rubber waste recycling. Recycled steel fibers can also be added to this concrete to improve its mechanical properties. This study investigates the effect of using different amounts of crumb rubber instead of aggregates both alone and in combination with recycled steel fibers on the mechanical properties and durability of roller-compacted concrete in pavements, including freeze-thaw resistance, water penetration, and water absorption. Moreover, the amount and size of rubber crumbs play an important role in the compressive strength of specimens under the freeze-thaw cycles. The designs with higher rubber contents had better compressive strength reduction under the freeze-thaw action, as the designs containing 14% cement and 0, 5, 10, 15, and 20% crumb rubber showed respectively 3.1, 16.8, 12.4, 9.5, and 7.9% strength reduction after 300 freeze-thaw cycles. Water absorption and water penetration depth increased in the specimens containing more crumb rubber. Adding recycled steel fibers did not positively impact the durability of specimens, as the designs containing 14% cement and 0, 30, and 45 kg/m3 of recycled steel fibers showed respectively 3.1, 4.7, and 4.9% strength reduction after 300 freeze-thaw cycles. Adding crumb rubber increases water penetration and water absorption. Also, durability parameters improved as cement content increased from 14% to 17%. | ||
