沥青混合料是由矿料（粗集料、细集料、填料）与沥青结合料拌和而成的混合料的总称。按施工温度，可分为热拌沥青混合料、温拌沥青混合料和冷拌沥青混合料。其中热拌沥青混合料是应用最广泛的类型，需要在高温下拌和、摊铺和碾压。

Asphalt mixture is a general term for a mixture made by mixing mineral aggregate (coarse aggregate, fine aggregate, filler) with asphalt binder. According to the construction temperature, it can be divided into hot mix asphalt mixture, warm mix asphalt mixture, and cold mix asphalt mixture. Among them, hot mix asphalt mixture is the most widely used type, which requires mixing, paving, and rolling at high temperatures.

普通沥青混合料（AC型） 是最基础的沥青混合料类型，采用连续密级配。AC型混合料适用于城镇次干道、辅路或人行道等场所。它施工成熟、成本相对较低，但在高温抗车辙和低温抗开裂方面性能有限。

Ordinary asphalt mixture (AC type) is the most basic type of asphalt mixture, which adopts continuous dense grading. AC type mixture is suitable for urban secondary roads, auxiliary roads, sidewalks and other places. It has mature construction and relatively low cost, but its performance in high-temperature anti rutting and low-temperature anti cracking is limited.

改性沥青混合料是在普通沥青中掺加橡胶、树脂、高分子聚合物、磨细的橡胶粉等改性剂，使沥青或沥青混合料的性能得以改善。与AC型相比，改性沥青混合料具有更高的高温抗车辙能力、良好的低温抗开裂能力、较高的耐磨耗能力和更长的使用寿命。改性沥青混合料面层适用于城镇快速路、主干路。

Modified asphalt mixture is the addition of rubber, resin, polymer, ground rubber powder and other modifiers to ordinary asphalt to improve the performance of asphalt or asphalt mixture. Compared with AC type, modified asphalt mixture has higher high-temperature rutting resistance, good low-temperature cracking resistance, higher wear resistance, and longer service life. The modified asphalt mixture surface layer is suitable for urban expressways and main roads.

沥青玛蹄脂碎石混合料（SMA） 是当前国内外使用较多的一种抗变形能力强、耐久性好的沥青面层混合料。SMA是一种间断级配的沥青混合料，5mm以上的粗骨料比例高达70%至80%，矿粉用量达7%至13%，沥青用量高达6.5%至7%。使用改性沥青的SMA混合料具有非常好的高温抗车辙能力、低温抗变形性能和水稳定性，且构造深度大、抗滑性能好。SMA适用于城镇快速路、主干路。

Asphalt mastic crushed stone mixture (SMA) is a widely used asphalt surface layer mixture with strong deformation resistance and good durability both domestically and internationally. SMA is an intermittent graded asphalt mixture, with a proportion of 70% to 80% coarse aggregate over 5mm, a mineral powder content of 7% to 13%, and an asphalt content of 6.5% to 7%. The SMA mixture using modified asphalt has excellent high-temperature rutting resistance, low-temperature deformation resistance, and water stability, as well as a large construction depth and good anti-skid performance. SMA is suitable for urban expressways and main roads.

此外，还有排水沥青混合料等特种类型，具有良好的排水和降噪功能。

In addition, there are special types such as drainage asphalt mixtures, which have good drainage and noise reduction functions.
