一立方沥青的重量因沥青类型、密度及环境条件不同而有所差异，综合搜索结果中的信息，主要范围如下：

　　The weight of one cubic meter of asphalt varies depending on the type, density, and environmental conditions of the asphalt. Based on the information in the search results, the main range is as follows:

　　普通沥青

　　Ordinary asphalt

　　道路石油沥青的密度通常为1.01~1.05吨/立方米，建筑石油沥青为1.05~1.15吨/立方米，因此一立方普通沥青约重1.0~1.2吨，常取平均值1.1吨进行估算。

　　The density of road petroleum asphalt is usually 1.01-1.05 tons/cubic meter, while that of building petroleum asphalt is 1.05-1.15 tons/cubic meter. Therefore, one cubic meter of ordinary asphalt weighs about 1.0-1.2 tons, and the average value of 1.1 tons is often taken for estimation.

　　改性沥青

　　modified asphalt

　　如SBS改性沥青，密度较高，约为1.1~1.3吨/立方米，一立方约重1.1~1.3吨。

　　SBS modified asphalt, with a high density of about 1.1-1.3 tons/cubic meter, weighs approximately 1.1-1.3 tons per cubic meter.

　　沥青混凝土

　　asphalt concrete

　　沥青与矿料混合后密度显著增加：

　　The density significantly increases after mixing asphalt and mineral aggregate:

　　细粒式沥青混凝土密度约2.35吨/立方米，一立方约2.35吨；

　　The density of fine-grained asphalt concrete is about 2.35 tons/cubic meter, and one cubic meter is about 2.35 tons;

　　中粒式约2.4吨/立方米，粗粒式约2.45吨/立方米。

　　The medium particle size is about 2.4 tons/cubic meter, and the coarse particle size is about 2.45 tons/cubic meter.

　　另有数据提到沥青混凝土整体密度可能达3吨/立方米，一立方约3吨。

　　Another data suggests that the overall density of asphalt concrete may reach 3 tons per cubic meter, with one cubic meter accounting for approximately 3 tons.

　　影响因素

　　influencing factors

　　温度：高温下沥青膨胀密度降低，低温时密度增大。

　　Temperature: The expansion density of asphalt decreases at high temperatures and increases at low temperatures.

　　成分：含蜡量高的沥青密度较低，改性剂或矿料比例也会影响最终重量。

　　Ingredients: Asphalt with high wax content has lower density, and the proportion of modifiers or mineral aggregates can also affect the final weight.

　　总结：

　　Summary:

　　纯沥青（未混合矿料）一立方约1.0~1.5吨；

　　One cubic meter of pure asphalt (unmixed mineral material) weighs approximately 1.0-1.5 tons;

　　沥青混凝土（混合料）一立方约2.2~3.0吨，具体需根据类型（细粒、中粒、粗粒）及配比确定。

　　Asphalt concrete (mixture) weighs approximately 2.2-3.0 tons per cubic meter, depending on the type (fine, medium, coarse) and mix ratio.

　　实际应用中建议参考供应商提供的密度数据或现场实测，以确保计算准确。

　　In practical applications, it is recommended to refer to the density data provided by suppliers or on-site measurements to ensure accurate calculations.
