很多项目经理比沥青料报价，只盯着“每吨便宜几块”。可真到摊铺那天，运距远、没盖保温篷布，混合料到场掉到120℃以下，摊铺机一振捣就散花，初压压不实、终压留轮迹——返工铣刨的钱，够把十车料的差价全吐出来。

Many project managers only focus on "how much cheaper per ton" compared to quoting asphalt. On the day of the paving, the transportation distance was far and the insulation tarpaulin was not covered. The mixture fell below 120 ℃ when it arrived, and the paver scattered flowers as soon as it was vibrated. The initial compaction was not solid, and the final compaction left wheel marks - the money for rework milling and planing was enough to cover the price difference of ten carts of materials.

热拌沥青料好不好，看三组数据就够了：

Whether the hot mix asphalt is good or not, three sets of data are enough:

温度链：出厂140–165℃，到场摊铺不低于130℃，初压保持120℃上下。温度一掉，沥青粘度上来，骨料裹不住，孔隙率超标，雨季一过就松散掉粒。

Temperature chain: Factory temperature range of 140-165 ℃, on-site paving temperature should not be lower than 130 ℃, and initial pressure should be maintained around 120 ℃. When the temperature drops, the viscosity of the asphalt increases, the aggregate cannot be wrapped, the porosity exceeds the standard, and the particles loosen and fall off after the rainy season.

级配和油石比：关键筛孔通过率按目标级配中值走，油石比一般落在4.0%–5.5%，偏大泛油、偏小发散，马歇尔稳定度和空隙率当场就能试出来。

Grading and oil stone ratio: The key sieve pass rate is based on the median value of the target grading, and the oil stone ratio generally falls between 4.0% and 5.5%, with excessive oil bleeding and insufficient divergence. Marshall stability and porosity can be tested on the spot.

石料底色：快速路、主干路优先玄武岩/石灰岩，针片状颗粒控制在15%以内，粘附性不达标的石料再便宜也别用。

Stone base color: Priority should be given to basalt/limestone for expressways and main roads, with needle shaped particles controlled within 15%. Stone materials with poor adhesion should not be used even if they are cheap.

采购时把“运距+保温车+到场测温”写进合同，每车附带出厂检测小条；进场随机抽一辆插温度计，不达标整车退回。别在料车旁边省那点检测时间，钻芯取不出来完整试件的时候，后悔的是你自己。

When purchasing, include "transportation distance+insulation vehicle+on-site temperature measurement" in the contract, and each vehicle comes with a factory inspection receipt; Randomly select one vehicle with a thermometer inserted upon entry, and return the entire vehicle if it does not meet the standards. Don't save any testing time next to the material truck. When you can't extract a complete specimen from the drill core, you regret it yourself.
