瀝青混凝土俗稱瀝青砼，人工選配具有一定級(jí)配組成的礦料，碎石或軋碎礫石、石屑或砂、礦粉等，與一定比例的路用瀝青材料，在嚴(yán)格控制條件下拌制而成的混合料。這里濟(jì)南瀝青料廠家將介紹瀝青混凝土的強(qiáng)度表現(xiàn)。
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.
瀝青混合料的強(qiáng)度主要表現(xiàn)在兩個(gè)方面：
The strength of asphalt mixtures is mainly manifested in two aspects:
一是瀝青與礦粉形成的膠結(jié)料的粘結(jié)力；
One is the bonding force of the binder formed by asphalt and mineral powder;
另一是集料顆粒間的內(nèi)摩阻力和鎖結(jié)力。
The other is the internal frictional resistance and locking force between aggregate particles.
礦粉細(xì)顆粒（大多小于0.075毫米）的巨大表面積使瀝青材料形成薄膜，從而提高了瀝青材料的粘結(jié)強(qiáng)度和溫度穩(wěn)定性；而鎖結(jié)力則主要在粗集料顆粒之間產(chǎn)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.
選擇瀝青混凝土礦料級(jí)配時(shí)要兼顧兩者，以達(dá)到加入適量瀝青后混合料能形成密實(shí)、穩(wěn)定、粗糙度適宜、經(jīng)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.
配合礦料有多種方法，可以用公式計(jì)算，也可以憑經(jīng)驗(yàn)規(guī)定級(jí)配范圍，國(guó)內(nèi)采用經(jīng)驗(yàn)曲線的級(jí)配范圍。
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.
瀝青混合料中的瀝青適宜用量，應(yīng)以試驗(yàn)室試驗(yàn)結(jié)果和工地實(shí)用情況來確定，一般在有關(guān)規(guī)范內(nèi)均列有可資參考的瀝青用量范圍作為試配的指導(dǎo)。
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.
當(dāng)?shù)V料品種、級(jí)配范圍、瀝青稠度和種類、拌和設(shè)施、地區(qū)氣候及交通特征較固定時(shí)，也可采用經(jīng)驗(yàn)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.
