Optimizing the Sustainability of Asphalt Pavements through Incorporating Crumb Rubber in High-Modulus Asphalt Concrete (HMAC) Mixtures in Louisiana
| 项目名称： | Optimizing the Sustainability of Asphalt Pavements through Incorporating Crumb Rubber in High-Modulus Asphalt Concrete (HMAC) Mixtures in Louisiana |
| 摘要： | The proposed research study will build on the results of the authors’ initial study, titled “Viability Assessment and Cost-Effectiveness of Using High-Modulus Asphalt Concrete (HMAC) as Base Course in Asphalt Pavements in Louisiana.” In specific, this project aims to optimize the performance, cost-effectiveness, and sustainability of HMAC mixtures using crumb rubber and local materials in Louisiana. To achieve this objective, high-modulus asphalt mixtures mimicking the European approach will be prepared using the Superpave specifications. These mixtures will include different percentages of crumb rubber, two PG grades, and different binder contents. The dynamic modulus as well as the performance of these mixtures against rutting and cracking will be evaluated in the laboratory. In addition, the field performance and cost-effectiveness of these mixtures will be predicted. The results of this study will provide solutions for fatigue and rutting failures in asphalt pavements in Region 6 enhancing the durability and service life of the road infrastructure. Furthermore, it will enhance the sustainability of the road infrastructure through using crumb rubber from scrap tires. |
