沥青车道应该做多厚？

5–7.5 厘米压实面层，下面是 10–20 厘米压实良好的碎石基层。经常停放卡车或房车时，面层加到 10 厘米、基层 20 厘米。

一吨沥青能铺多少面积？

压实厚度 5 厘米时约 7.4 平方米，7.5 厘米时约 5 平方米。覆盖面积与厚度成反比。

气温多低就不能摊铺沥青了？

低于约 10°C 时混合料在压实前就冷却，未压实到位的沥青会过早破坏。多数施工队在夜间持续接近冰点时停工。

新铺沥青多久能通车？

视气温 24–72 小时后可通行轻型车辆。完全固化需 6–12 个月，第一个夏天避免长时间停在同一位置或原地打方向。

沥青下面必须做基层吗？

必须。沥青属于柔性路面，靠扩散荷载而非自身跨越，其性能完全取决于下面的基层。省掉基层是几年内就破坏的首要原因。

吨数 = (长 × 宽 × 厚 ft × 密度 lb/ft³ × (1 + 损耗)) ÷ 2000

参考资料

Measure what the tool asks for
This calculator works from 长度 in ft, 宽度 in ft and 压实厚度 in in. Measure the finished area you are covering, not the material — an estimate is only as good as the dimensions you feed it.
What it does with those numbers
吨数 = (长 × 宽 × 厚 ft × 密度 lb/ft³ × (1 + 损耗)) ÷ 2000 Every figure on the page comes out of that one expression, so you can check it by hand.
Why it adds 5% waste
施工队通常多订 5%，用于边缘摊铺、压实差异以及车厢内残留的料。
Where the numbers come from
The constants are taken from Asphalt Institute — MS-22 Construction of Hot Mix Asphalt Pavements and National Asphalt Pavement Association — Design and construction guidance, linked in full below. If a figure here disagrees with your supplier's spec sheet, use the spec sheet — it describes the product you are buying.
What this will not tell you
This is a material takeoff, not a bid. It does not price labour, permits, delivery, equipment hire or site preparation, and it assumes a straightforward layout. Complex cuts, difficult access and awkward shapes all cost more than the geometry suggests.

常见问题

把长、宽、压实厚度（英尺）相乘，乘以密度（约 145 lb/ft³），再除以 2,000 得吨数。12 × 3.7 米、厚 7.5 厘米的车道约需 8.7 吨。
