| Application of the foamed asphalt techniques in recycling the waste asphalt shows that large quantify of waste asphalt(60$sim$70% of the total mix) can be used comparing with hot mix asphalt techniques and also is environmentally safe. However, the constant quality of the recycling foamed asphalt mixtures is not readily achieved and can not be applied to the heavy traffic road due to the characteristics of the conventional foamed asphalt mixtures. The semi-hot technique that the RAP and the aggregate is heated below $100^{circ}C$ is adopted in this study and expected to solve the problems of conventional foamed asphalt mixtures. This study presents the viability of the semi-hot foamed asphalt mixtures when using the RAP. The semi-hot recycling foamed mixtures are tested and evaluated in the laboratory. The test results including coating rates, creep tests, resilient modulus tests, indirect tensile tests and the Marshall stability tests showed significant improvement. |
