路面機械選型配套是技術(shù)活。設(shè)備配不對，再好的混合料也鋪不出好路。核心原則：主要機械定型號，配套機械圍著轉(zhuǎn)——攪拌設(shè)備或攤鋪機是“老大”，其他設(shè)備按它的產(chǎn)能來配。

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.

攤鋪機怎么選？ 基層施工宜用多臺同規(guī)格攤鋪機全幅攤鋪。農(nóng)村公路6-7m寬路面，一臺中型攤鋪機加兩臺中型壓路機就夠了。高等級公路面層，攤鋪寬度8-8.5m，攤鋪速度需與拌和能力匹配。

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.

壓路機怎么配？ 突出分三步：初壓用雙鋼輪壓路機（靜態(tài)）2遍；復壓用振動壓路機或輪胎壓路機；終壓用雙鋼輪壓路機（靜壓）消除輪跡。突出從外側(cè)向內(nèi)側(cè)進行，并列輪重疊40cm左右。壓路機嚴禁在新鋪混合料上調(diào)頭、轉(zhuǎn)向或急剎車。

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.

數(shù)量怎么算？ 先確定主要機械（攪拌站或攤鋪機）的產(chǎn)能，再計算配套機械數(shù)量。攤鋪機數(shù)量看寬度和速度，壓路機數(shù)量看突出速度和壓實遍數(shù)。設(shè)備數(shù)量要留余量，防止一臺趴窩全線停工。

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.
