| 1、混合料分为粗集料和细集料，在粗集料中影响抗剥落剂拌合的质量因素有软石和片状颗粒，而细集料有石屑、人工机制砂以及天然砂等。 1. The mixture is divided into coarse aggregate and fine aggregate. The quality factors affecting the mixing of anti stripping agent in the coarse aggregate are soft stone and flake particles, while the fine aggregate includes stone chips, artificial sand and natural sand. 2、在进行自卸车卸料时，粗集料在车厢周围，细集料在中间，这就形成了集料的离析现象，所以在卸料时应采用前、中、后三次卸料方式。 2. In the unloading process of dump truck, the coarse aggregate is around the car, and the fine aggregate is in the middle, which forms the segregation of aggregate. Therefore, the three unloading methods of front, middle and back should be adopted. 3、拌合过程的影响可以从两方面来分析：(1)时间长度：虽然说混合料与抗剥落剂拌和的时间越长，就越均匀，但是如果时间过长会导致沥青的老化，从而影响到混合料的质量;(2)材料波动：在很大程度上细料用量的波动会影响到总的矿料表面积，从而影响到沥青膜的厚度，而该厚度是混合料质量的重要指标，所以拌和中要控制好细料的用量。 3. The influence of mixing process can be analyzed from two aspects: (1) time length: Although the longer the mixing time of mixture and anti stripping agent is, the more uniform it will be, but if the time is too long, it will lead to the aging of asphalt, thus affecting the quality of mixture; (2) material fluctuation: to a large extent, the fluctuation of fine material consumption will affect the total surface area of mineral material, thus affecting the asphalt film The thickness is an important index of mixture quality, so the amount of fine material should be controlled during mixing. |
