沥青混合料的强度主要表现在两个方面
来源：/ 日期：2023-07-07
沥青混凝土俗称沥青砼，人工选配具有一定级配组成的矿料，碎石或轧碎砾石、石屑或砂、矿粉等，与一定比例的路用沥青材料，在严格控制条件下拌制而成的混合料。这里济南沥青料厂家将介绍沥青混凝土的强度表现。
Asphalt concrete, commonly known as asphalt concrete, is a mixture of manually selected mineral materials with a certain grading composition, such as crushed stone or crushed gravel, stone chips or sand, mineral powder, etc., mixed with a certain proportion of road asphalt materials under strict control conditions. Here, Jinan asphalt material manufacturer will introduce the strength performance of asphalt concrete.
沥青混合料的强度主要表现在两个方面：
The strength of asphalt mixtures is mainly manifested in two aspects:
一是沥青与矿粉形成的胶结料的粘结力；
One is the bonding force of the binder formed by asphalt and mineral powder;
另一是集料颗粒间的内摩阻力和锁结力。
The other is the internal frictional resistance and locking force between aggregate particles.
矿粉细颗粒（大多小于0.075毫米）的巨大表面积使沥青材料形成薄膜，从而提高了沥青材料的粘结强度和温度稳定性；而锁结力则主要在粗集料颗粒之间产生。
The huge surface area of fine particles of mineral powder (mostly less than 0.075 millimeters) forms a thin film of asphalt material, thereby improving the bonding strength and temperature stability of asphalt material; The locking force is mainly generated between the coarse aggregate particles.
选择沥青混凝土矿料级配时要兼顾两者，以达到加入适量沥青后混合料能形成密实、稳定、粗糙度适宜、经久耐用的路面。
When selecting the gradation of asphalt concrete mineral aggregate, both should be taken into account to achieve a dense, stable, moderately rough, and durable road surface after adding an appropriate amount of asphalt.
配合矿料有多种方法，可以用公式计算，也可以凭经验规定级配范围，国内采用经验曲线的级配范围。
There are various methods for mixing mineral materials, which can be calculated using formulas or specified based on experience. In China, the grading range of the experience curve is used.
沥青混合料中的沥青适宜用量，应以试验室试验结果和工地实用情况来确定，一般在有关规范内均列有可资参考的沥青用量范围作为试配的指导。
The appropriate amount of asphalt in asphalt mixtures should be determined based on laboratory test results and practical conditions on the construction site. Generally, there are reference asphalt dosage ranges listed in relevant specifications as guidance for trial mixing.
当矿料品种、级配范围、沥青稠度和种类、拌和设施、地区气候及交通特征较固定时，也可采用经验公式估算。
When the variety of mineral materials, grading range, asphalt consistency and type, mixing facilities, regional climate, and traffic characteristics are relatively fixed, empirical formulas can also be used for estimation.
That's all for the main performance of asphalt mixture strength. I hope it can be helpful to you. For more information, please come to our website Consult and understand!
