🛣️ 沥青用量计算器Asphalt Calculator

使用说明与常见问题How-to & FAQ

「沥青用量计算器」是什么？What is the Asphalt Calculator tool?

按铺设面积和压实厚度计算热拌沥青混合料的体积和吨数（默认密度 145 lb/ft³ ≈ 2.32 t/m³），可输入单价估算材料费，适合车道、停车场铺设。Estimate hot-mix asphalt volume and tonnage for a driveway or parking lot from the area and compacted thickness (default density 145 lb/ft³ ≈ 2.32 t/m³), with an optional price per ton.

如何使用「沥青用量计算器」？How do I use the Asphalt Calculator tool?

在「沥青用量计算器」中，填写「单位制」、「长度（英尺/米）」、「宽度（英尺/米）」、「压实厚度（英寸/厘米）」、「密度(lb/ft³ / kg/m³)」等参数，结果会随输入实时计算并显示在下方。In the Asphalt Calculator: Fill in "Units", "Length (ft / m)", "Width (ft / m)", "Compacted thickness (in / cm)", "Density (lb/ft³ / kg/m³)"; results are recalculated instantly as you type.

沥青吨数怎么算？How is tonnage calculated?

吨数 = 面积 × 厚度 × 密度。默认密度 145 lb/ft³（约 2,323 kg/m³）是常用估算值（示例值）；实际压实密度随级配和压实度变化，请以供应商或配合比设计给出的数值为准。公制下密度按 kg/m³ 输入，切换单位制会自动换算。1 美吨 = 2,000 磅，1 公吨 = 1,000 千克；单价按你选择的吨位计算。Tons = area × thickness × density. The default 145 lb/ft³ (about 2,323 kg/m³) is a common estimating value (example default); real compacted density depends on the mix and compaction, so use your supplier's or mix design's figure. In metric mode density is entered in kg/m³, and switching units converts it. A US ton is 2,000 lb and a metric tonne 1,000 kg; the price uses the ton you choose.

车道要铺多厚？How thick should a driveway be?

常见做法是在压实碎石基层上铺 2–3 英寸（5–7.5 cm）沥青面层，重型车辆通行处更厚；订购时多加约 5–10% 余量。这些都是经验值（示例值），请以当地规范和施工方建议为准。A common practice is 2–3 in (5–7.5 cm) of asphalt over a compacted aggregate base, more for heavy traffic, and ordering about 5–10% extra. These are rules of thumb (example values); follow local codes and your contractor.
