Paper Title:
Experiments and Study on Proportioning Design of SMA-13 Warm Mix Asphalt
  Abstract

Materials, include polymer modified asphalt, coarse aggregate, fine aggregate, packing and lignin fiber, of SMA-13 Warm Mix Asphalt used in maintenance engineering of Jing-Shen expressway (K17-K22), were tested in quality. Based on different grading Marshall tests of stone matrix asphalt of HMA (no additive) and WMA (with additives), materials proportion, asphalt aggregate ratio and target densities of SMA-13 WMA were designed, which will be applied in expressway surface maintenance. Through rutting test, water immersion Marshall test, tensile strength ratio test, seepage test and other proportioning examinations, it shows that the designed asphalt can meet code requirements and guarantee good high temperature stability and water stability.
