修路这件事，外行看的是路面黑不黑、平不平，内行看的是材料配比和施工工艺。沥青料作为路面非常上面那一层，承受着车辆突出、雨水冲刷和四季温差，它要是出了问题，后面修补的代价比当初多花的那点材料钱大得多。尤其是市政道路和小区路面，车流量不大但修补起来要封路、要协调，费时费力。

When it comes to road construction, the layman looks at whether the road surface is black or uneven, while the expert looks at the material ratio and construction technology. Asphalt material, as the topmost layer of the road surface, bears the pressure of vehicle crushing, rainwater erosion, and seasonal temperature differences. If there is a problem with it, the cost of repairing it later is much higher than the extra material money spent initially. Especially for municipal roads and residential road surfaces, the traffic flow is not large, but repairing them requires road closures and coordination, which is time-consuming and laborious.

先看沥青料的配比和级配，这是路面寿命的底子。 沥青料由沥青、粗集料、细集料和矿粉按一定比例混合而成，配合比设计决定了它的强度、稳定性和耐久性。粗集料太多，路面容易松散；细集料和沥青用量过高，高温下容易泛油、车辙。济南夏天路面温度能到六七十度，如果沥青软化点不够或者级配不合理，重车一压就变形。采购时不能只问“什么标号的沥青”，要了解集料的级配曲线和油石比，这些参数比沥青标号更能反映材料的实际性能。

First, look at the ratio and grading of asphalt material, which is the foundation of the pavement life. Asphalt material is composed of asphalt, coarse aggregate, fine aggregate, and mineral powder mixed in a certain proportion, and the mix design determines its strength, stability, and durability. Too much coarse aggregate makes the road surface prone to looseness; Excessive use of fine aggregate and asphalt can lead to oil bleeding and rutting at high temperatures. In summer, the road surface temperature in Jinan can reach up to 60-70 degrees Celsius. If the asphalt softening point is not enough or the grading is not reasonable, heavy vehicles will deform when pressed. When purchasing, it is not enough to just ask "what grade of asphalt", but to understand the grading curve and asphalt aggregate ratio of the aggregate. These parameters can better reflect the actual performance of the material than the asphalt grade.

骨料质量，是很多低价沥青料的隐形短板。 沥青料里的石子占了大部分体积，石子的压碎值、磨光值、含泥量直接影响路面的抗滑性和耐久性。有些厂家为了降成本，用强度不够的石料或者含泥量超标的砂子，拌出来的料看着没差别，铺到路上跑不了几个月就掉粒、露骨。尤其是济南周边有些石料厂的材质偏软，压碎值偏高，用这种骨料做的沥青路面，重载车一过就容易破损。采购时非常好了解骨料的来源和检测报告，不能只看沥青料的外观。

The quality of aggregates is a hidden weakness for many low-priced asphalt materials. The stones in the asphalt material account for the majority of the volume, and the crushing value, polishing value, and mud content of the stones directly affect the skid resistance and durability of the road surface. Some manufacturers, in order to reduce costs, use stone materials with insufficient strength or sand with excessive mud content. The mixed material looks similar, but it falls off and becomes exposed on the road within a few months. Especially in the vicinity of Jinan, some stone factories have soft materials and high crushing values. Asphalt pavements made with this type of aggregate are prone to damage when overloaded vehicles pass by. It is best to understand the source and testing report of the aggregate when purchasing, rather than just looking at the appearance of the asphalt material.

拌合温度和运输时间，是施工中容易被忽略的关键。 沥青料出厂温度有严格要求，温度太低摊铺时压不实，温度太高沥青老化变脆。从拌合站到工地的运输时间也要控制，运距太远或者路上耽搁太久，到场温度不够，压实度就上不去。济南本地的沥青料厂家，运距短是优势，但也要看拌合站的产能和调度能力，高峰期供不上料，工地等米下锅，摊铺质量也跟着受影响。另外，摊铺时的初压、复压、终压温度都要控制好，压实度不够的路面，用不了多久就出现坑槽。

Mixing temperature and transportation time are key factors that are easily overlooked during construction. There are strict requirements for the factory temperature of asphalt materials. If the temperature is too low, it will not be compacted during paving, and if the temperature is too high, the asphalt will age and become brittle. The transportation time from the mixing station to the construction site should also be controlled. If the transportation distance is too far or the road is delayed for too long, the arrival temperature is not enough, and the compaction degree cannot be improved. Local asphalt material manufacturers in Jinan have the advantage of short transportation distance, but it also depends on the production capacity and scheduling ability of the mixing station. During peak periods, if there is no supply of materials, the construction site will wait for rice to be cooked, and the paving quality will also be affected. In addition, the initial compaction, re compaction, and final compaction temperatures during paving should be well controlled. Road surfaces with insufficient compaction will soon develop potholes.

选供应商，看的是综合实力而不是单次报价。 沥青料是重货，运输成本占比高，本地有拌合站的厂家在供货及时性和运费上有天然优势。另外，沥青路面从材料到施工是一体的，厂家如果同时具备施工资质和施工队伍，能减少材料和施工之间的扯皮。有些项目材料是一家、施工是另一家，出了问题两边推，非常后吃亏的是业主。选供应商时可以了解它的拌合站规模、日产能、配送车辆数量，以及之前做过哪些类似项目，这些比一次报价更能说明问题。

Choosing a supplier is based on comprehensive strength rather than a single quotation. Asphalt material is a heavy commodity with a high proportion of transportation costs. Local manufacturers with mixing stations have a natural advantage in timely supply and shipping costs. In addition, asphalt pavement is integrated from materials to construction. If the manufacturer has both construction qualifications and construction teams, it can reduce the friction between materials and construction. Some projects have one supplier for materials and another for construction, and when problems arise, both parties push the blame, with the owner ultimately suffering losses. When selecting a supplier, you can learn about their mixing plant scale, daily production capacity, number of delivery vehicles, and previous similar projects, which are more indicative than a single quotation.

济南沥青料市场供应充足，但路面质量参差不齐。把配比、骨料、运输、供应商实力这几件事弄清楚，修出来的路才能扛得住车压和日晒。

The Jinan asphalt market has sufficient supply, but the quality of road surfaces varies. Only by understanding the proportioning, aggregates, transportation, and supplier strength can the repaired road withstand the pressure of vehicles and sunlight.
