　　瀝青料的分類有哪些？

　　What are the classifications of asphalt materials?

　　瀝青混凝土按所用結合料不同，可分為石油瀝青的和煤瀝青的兩大類；有些國家或地區(qū)亦有采用或摻用天然瀝青拌制的。

　　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.

　　按所用集料品種不同，可分為碎石的、礫石的、砂質的、礦渣的數(shù)類，以碎石采用最為普遍。按混合料最大顆粒尺寸不同，可分為粗粒（35～40毫米以下）、中粒（20～25毫米以下）、細粒（10～15毫米以下）、砂粒（5～7毫米以下）等數(shù)類。

　　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).

　　按混合料的密實程度不同，可分為密級配、半開級配和開級配等數(shù)類，開級配混合料也稱瀝青碎石。其中熱拌熱鋪的密級配碎石混合料經(jīng)久耐用，強度高，整體性好，是修筑高級瀝青路面的代表性材料，應用得最廣。

　　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.

　　各國對瀝青混凝土制訂有不同的規(guī)范，中國制定的熱拌熱鋪瀝青混合料技術規(guī)范，以空隙率10%及以下者稱為瀝青混凝土，又細分為Ⅰ型和Ⅱ型，Ⅰ型的孔隙率為3（或2）～6%，屬密級配型；Ⅱ型為6～10%，屬半開級配型；空隙率10%以上者稱為瀝青碎石，屬開級配型；混合料的物理力學指標有穩(wěn)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.
