路面机械选型配套是技术活。设备配不对，再好的混合料也铺不出好路。核心原则：主要机械定型号，配套机械围着转——搅拌设备或摊铺机是“老大”，其他设备按它的产能来配。

The selection and matching of road machinery is a technical activity. If the equipment is not properly matched, even the best mixture cannot pave a good road. Core principle: The leading machinery determines the model, and the supporting machinery revolves around it - the mixing equipment or paver is the "boss", and other equipment is matched according to its production capacity.

摊铺机怎么选？ 基层施工宜用多台同规格摊铺机全幅摊铺。农村公路6-7m宽路面，一台中型摊铺机加两台中型压路机就够了。高等级公路面层，摊铺宽度8-8.5m，摊铺速度需与拌和能力匹配。

How to choose a paver? Multiple pavers of the same specifications should be used for full width paving during grassroots construction. A rural road with a width of 6-7 meters is sufficient with one medium-sized paver and two medium-sized rollers. The surface layer of high-grade highways should have a paving width of 8-8.5m, and the paving speed should match the mixing capacity.

压路机怎么配？ 突出分三步：初压用双钢轮压路机（静态）2遍；复压用振动压路机或轮胎压路机；终压用双钢轮压路机（静压）消除轮迹。突出从外侧向内侧进行，并列轮重叠40cm左右。压路机严禁在新铺混合料上调头、转向或急刹车。

How to equip a road roller? Rolling is divided into three steps: initial rolling using a double drum roller (static) for 2 passes; Vibration roller or tire roller for re compaction; Use a double drum roller (static pressure) for final compaction to eliminate wheel marks. Rolling is carried out from the outside to the inside, with parallel wheels overlapping by about 40cm. It is strictly prohibited for the roller to turn, turn or brake abruptly on the newly laid mixture.

数量怎么算？ 先确定主要机械（搅拌站或摊铺机）的产能，再计算配套机械数量。摊铺机数量看宽度和速度，压路机数量看突出速度和压实遍数。设备数量要留余量，防止一台趴窝全线停工。

How to calculate the quantity? First determine the production capacity of the main machinery (mixing plant or paver), and then calculate the number of supporting machinery. The number of pavers depends on the width and speed, while the number of rollers depends on the rolling speed and number of passes. There should be a surplus in the number of devices to prevent one machine from collapsing and the entire line from shutting down.
