Asphalt mixture for heavy traffic and preparation method thereof
The invention relates to the technical field of asphalt modified mixtures, and discloses an asphalt mixture for heavy traffic, which is prepared from the following components in parts by weight: 5-15 parts of rubber modified asphalt, 1-5 parts of an additive and 80-90 parts of stone, the invention also provides a preparation method of the asphalt mixture for heavy traffic. The preparation method comprises the following steps: S1, preparing the rubber modified asphalt; s2, mixing and heating: putting the designed amount of stone into a high-temperature forced air drying oven, keeping the temperature at 180-190 DEG C, then putting the heated stone into an automatic mixing pot, adding an additive, and carrying out dry mixing for 30-60 seconds. According to the present invention, the cost is low, the problem of poor adhesion between the original pavement and the asphalt surface layer can be eliminated, the adhesion between the layers of the pavement can be improved, and the asphalt mixture has advantages of high dynamic stability, good freeze-thaw splitting strength index, low 70 DEG C water immersion flying loss, excellent shear resistance, excellent compressive strength and long service life.
本发明涉及沥青改混合料技术领域，且公开了一种重载交通用沥青混合料，配方包括：橡胶改性沥青5‑15份、外加剂1‑5份、石料80‑90份；本发明还提出了一种重载交通用沥青混合料制备方法，包括以下步骤：S1：制备橡胶改性沥青；S2：混合加热，把设计用量的石料放入高温鼓风干燥烘箱中，恒温至180‑190摄氏度，然后将加热好的石料放入自动拌合锅中，并加入外加剂，干拌30‑60s。本发明成本低，可以消除原路面与沥青面层之间粘结性差的问题，提高路面各层之间的粘结力，而且这种沥青混合料动稳定度高，冻融劈裂强度指标好，70℃浸水飞散损失小，具有优异的抗剪性能及抗压强度性能和使用寿命。
