舊路面預(yù)處理

　　Pre treatment of old road surface

　　局部隆起、凹陷等，保證良好的下承層。

　　Remove local bumps, depressions, etc. to ensure a good underlying layer.

　　檢測舊路彎沉、結(jié)構(gòu)層厚度、材料土質(zhì)等，為再生施工提供數(shù)據(jù)支持。

　　Detect the deflection of old roads, thickness of structural layers, material and soil properties, etc., to provide data support for recycling construction.

　　銑刨與破碎

　　Milling and crushing

　　使用冷再生機(jī)對舊瀝青混凝土路面進(jìn)行銑刨和破碎，得到再生骨料。

　　Using cold recycling technology to mill and crush old asphalt concrete pavement to obtain recycled aggregates.

　　控制銑刨、破碎深度，確保再生底基層厚度滿足設(shè)計要求。

　　Control milling and crushing depth to ensure that the thickness of the regenerated subgrade meets the design requirements.

　　拌和與整形

　　Mixing and shaping

　　將再生骨料、新集料（如有需要）、水泥等按設(shè)定配比進(jìn)行拌和。

　　Mix recycled aggregates, new aggregates (if necessary), cement, etc. according to the set ratio.

　　拌和過程中，需控制含水量和拌和時間，確保拌和均勻。

　　During the mixing process, it is necessary to control the moisture content and mixing time to ensure even mixing.

　　使用平地機(jī)等設(shè)備對拌和后的混合料進(jìn)行整形，使其達(dá)到設(shè)計要求的形狀和坡度。

　　Use equipment such as a grader to shape the mixed material to meet the design requirements for shape and slope.

　　攤鋪與壓實

　　Laying and compaction

　　將整形后的混合料均勻攤鋪在路面上。

　　Spread the shaped mixture evenly on the road surface.

　　使用振動壓路機(jī)、輪胎壓路機(jī)等設(shè)備進(jìn)行壓實，確保壓實度滿足設(shè)計要求。

　　Use equipment such as vibratory rollers and tire rollers for compaction to ensure that the compaction degree meets the design requirements.

　　壓實過程中，需控制碾壓速度、遍數(shù)和含水量，避免過壓或欠壓。

　　During the compaction process, it is necessary to control the rolling speed, number of passes, and moisture content to avoid over pressure or under pressure.

　　養(yǎng)生與檢測

　　Health Preservation and Testing

　　壓實完成后，對路面進(jìn)行養(yǎng)生，確保水分逐步散失、混凝土強(qiáng)度增加。

　　After compaction is completed, the road surface should be cured to ensure gradual loss of moisture and increase in concrete strength.

　　養(yǎng)生期間，需保持路面濕潤，避免干燥開裂。

　　During the health preservation period, it is necessary to keep the road surface moist to avoid dryness and cracking.

　　養(yǎng)生結(jié)束后，對路面進(jìn)行檢測，包括壓實度、強(qiáng)度等指標(biāo)，確保滿足設(shè)計要求。

　　After the health preservation is completed, the road surface should be tested, including compaction degree, strength and other indicators, to ensure that it meets the design requirements.
