　　沥青料的分类有哪些？

　　What are the classifications of asphalt materials?

　　沥青混凝土按所用结合料不同，可分为石油沥青的和煤沥青的两大类；有些或地区亦有采用或掺用天然沥青拌制的。

　　Asphalt concrete can be divided into two categories based on the different binders used: petroleum asphalt and coal tar asphalt; Some countries or regions also use or mix natural asphalt for mixing.

　　按所用集料品种不同，可分为碎石的、砾石的、砂质的、矿渣的数类，以碎石采用为普遍。按混合料颗粒尺寸不同，可分为粗粒（35～40毫米以下）、中粒（20～25毫米以下）、细粒（10～15毫米以下）、砂粒（5～7毫米以下）等数类。

　　According to the different types of aggregates used, they can be divided into several categories: crushed stone, gravel, sandy, and slag, with crushed stone being the most commonly used. According to the different maximum particle sizes of the mixture, it can be divided into several categories: coarse particles (less than 35-40 millimeters), medium particles (less than 20-25 millimeters), fine particles (less than 10-15 millimeters), and sand particles (less than 5-7 millimeters).

　　按混合料的密实程度不同，可分为密级配、半开级配和开级配等数类，开级配混合料也称沥青碎石。其中热拌热铺的密级配碎石混合料经久耐用，强度高，整体性好，是修筑沥青路面的代表性材料，应用得广。

　　According to the different compactness of the mixture, it can be divided into several categories, such as dense grading, semi open grading, and open grading. Open graded mixtures are also known as asphalt crushed stones. Among them, the dense graded crushed stone mixture of hot mix and hot paving is durable, high in strength, and has good integrity. It is a representative material for constructing high-grade asphalt pavement and is widely used.

　　各国对沥青混凝土制订有不同的规范，制定的热拌热铺沥青混合料技术规范，以空隙率10%及以下者称为沥青混凝土，又细分为Ⅰ型和Ⅱ型，Ⅰ型的孔隙率为3（或2）～6%，属密级配型；Ⅱ型为6～10%，属半开级配型；空隙率10%以上者称为沥青碎石，属开级配型；混合料的物理力学指标有稳定度、流值和孔隙率等。

　　Different countries have different specifications for asphalt concrete. The technical specifications for hot mix and hot laid asphalt mixtures formulated by China refer to asphalt concrete with a porosity of 10% or less, which is further divided into Type I and Type II. Type I has a porosity of 3 (or 2) to 6%, belonging to the dense grading type; Type II is 6-10%, belonging to the semi open graded type; Those with a porosity of more than 10% are called asphalt crushed stones and belong to the open graded type; The physical and mechanical indicators of the mixture include stability, flow value, and porosity.
