|For the past ten years, engineers have been deeply researching the permeability of asphalt concrete. High-air voids have generally been the main indicator of permeable hot asphalt concrete in the work that has been done. The prediction of the field permeability values is inconsistent with that indicated in the current published literature. Furthermore, the precise correlations between the various components influencing the field permeability are unclear and complex.
One of our objectives of this research work is to present the investigations performed using the model-ling of Hot Mix Asphalt's (HMA's) field permeability using crumb rubber (CR). The primary benefit of using crumb rubber in asphalt mixture is to produce pavement that could be friendly and environmentally acceptable from a duration usable point of view. Other benefits of this procedure are to decrease the friction phenomena on pavement surfaces and improve the mechanical and long-term qualities of the asphalt mixture. This study's findings are presented to explore the benefits of employing crumb rubber to minimize excessive water infiltration and optimize field permeability.
This paper offers a significant and straightforward method for comprehending the variables influencing permeability. Asphalt was modified using a fine crumb rubber shred (2.36 - 0.85 mm) that was produced by grinding used truck tires at room temperature. Using the dry process method, the fine crumb rubber with varying contents (2.5%, 4.5%, and 6.5%) was added to the mixture. Hot Mix Asphalt's (HMA) field permeability must be regulated to avoid excessive water infiltration, which can cause an early failure of asphalt pavements.
