為了準(zhǔn)確確定舊路瀝青層厚度、基層材料和基層厚度,可以通過現(xiàn)場冷再生技術(shù)對舊路結(jié)構(gòu)材料進(jìn)行破碎取樣,掌握結(jié)構(gòu)強(qiáng)度。為了確定添加劑的類型和數(shù)量,必須詳細(xì)分析舊道路結(jié)構(gòu)材料的土壤質(zhì)量。
In order to accurately determine the thickness of asphalt layer, base material and base layer of the old road, it is possible to break and sample the old road structural materials through the cold recycling technology on site to master the structural strength. In order to determine the type and quantity of additives, the soil quality of old road structural materials must be analyzed in detail.
路面改造工程冷再生施工技術(shù)
3 cold regeneration construction technology of pavement reconstruction project
(1)試驗(yàn)段施工。通過試驗(yàn)段的施工,可以驗(yàn)證施工數(shù)據(jù),確定合理的配合比。選定的試驗(yàn)路段路面被壓碎并取樣后,進(jìn)行施工。施工過程中,人員記錄各種參數(shù)和存在的問題。在試驗(yàn)段施工過程中,通過多次試驗(yàn)確定了更佳參數(shù)。試驗(yàn)段施工完成后,對施工中出現(xiàn)的問題進(jìn)行分析研究,并探索相應(yīng)的解決方法,以避免正式施工中出現(xiàn)類似問題。
(1) Test section construction. Through the construction of the test section, the construction data can be verified and the reasonable mix proportion can be determined. After the pavement of the selected test section is crushed and sampled, the construction shall be carried out. In the process of construction, professionals record various parameters and existing problems. In the construction process of the test section, the best parameters are determined through many tests. After the completion of the construction of the test section, analyze and study the problems in the construction, and explore the corresponding solutions to avoid similar problems in the formal construction.
(2)攤鋪?zhàn)鳂I(yè)。首先是粗骨料的攤鋪?zhàn)鳂I(yè)。根據(jù)相關(guān)標(biāo)準(zhǔn)和試驗(yàn)段提供的數(shù)據(jù),合理確定粗骨料的用量,確保70%的舊路面覆蓋均勻。其次,采用正方形網(wǎng)格法鋪水泥。在此過程中,水泥用量保持在5%范圍內(nèi),實(shí)際水泥用量根據(jù)再生層厚度確定。為攤鋪的均勻性,避免出現(xiàn)網(wǎng)格空白或水泥堆積的現(xiàn)象。在水泥攤鋪過程中,人工攤鋪與冷再生機(jī)保持一定的距離,并根據(jù)冷再生機(jī)的運(yùn)行速度合理調(diào)整攤鋪進(jìn)度,避免水泥初凝攤鋪時(shí)間過長,不僅延誤施工進(jìn)度,而且影響現(xiàn)場冷再生技術(shù)的施工質(zhì)量。
(2) Paving operation. The first is the spreading of coarse aggregate. According to the relevant standards and the data provided by the test section, the amount of coarse aggregate shall be reasonably determined to ensure that 70% of the old pavement is covered evenly. Secondly, the square grid method is used to pave cement. In this process, the cement consumption is kept within 5%, and the actual cement consumption is determined according to the thickness of regeneration layer. In order to ensure the uniformity of paving and avoid the phenomenon of blank grid or cement accumulation. In the process of cement paving, keep a certain distance between manual paving and cold recycling, and reasonably adjust the paving progress according to the operation speed of cold recycling machine to avoid the long time of cement initial setting paving, which not only delays the construction progress, but also affects the construction quality of cold recycling technology on site.
