瀝青混合料是由礦料（粗集料、細集料、填料）與瀝青結(jié)合料拌和而成的混合料的總稱。按施工溫度，可分為熱拌瀝青混合料、溫拌瀝青混合料和冷拌瀝青混合料。其中熱拌瀝青混合料是應(yīng)用非常廣泛的類型，需要在高溫下拌和、攤鋪和突出。

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.

普通瀝青混合料（AC型） 是非?；A(chǔ)的瀝青混合料類型，采用連續(xù)密級配。AC型混合料適用于城鎮(zhèn)次干道、輔路或人行道等場所。它施工成熟、成本相對較低，但在高溫抗車轍和低溫抗開裂方面性能有限。

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.

改性瀝青混合料是在普通瀝青中摻加橡膠、樹脂、高分子聚合物、磨細的橡膠粉等改性劑，使瀝青或瀝青混合料的性能得以改善。與AC型相比，改性瀝青混合料具有更高的高溫抗車轍能力、良好的低溫抗開裂能力、較高的耐磨耗能力和更長的使用壽命。改性瀝青混合料面層適用于城鎮(zhèn)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.

瀝青瑪蹄脂碎石混合料（SMA） 是當前國內(nèi)外使用較多的一種抗變形能力強、耐久性好的瀝青面層混合料。SMA是一種間斷級配的瀝青混合料，5mm以上的粗骨料比例高達70%至80%，礦粉用量達7%至13%，瀝青用量高達6.5%至7%。使用改性瀝青的SMA混合料具有非常好的高溫抗車轍能力、低溫抗變形性能和水穩(wěn)定性，且構(gòu)造深度大、抗滑性能好。SMA適用于城鎮(zhèn)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，還有排水瀝青混合料等特種類型，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.
