水穩(wěn)基層施工條件

　　Construction conditions for water stable base layer

　　水穩(wěn)施工前路床的要求主要包括以下幾點：

　　The requirements for the roadbed before water stable construction mainly include the following points:

　　1. 路床表面狀態(tài)：路床表面應(yīng)平整、堅實，其高程、中線偏位、寬度、橫坡度和平整度等應(yīng)符合《公路路基施工技術(shù)規(guī)范》的規(guī)定。

　　1. Surface condition of roadbed: The roadbed surface should be flat and solid, and its elevation, centerline deviation, width, cross slope, and flatness should comply with the provisions of the "Technical Specification for Construction of Highway Roadbeds".

　　2. 清潔度：在鋪筑水泥穩(wěn)定碎石底基層前，應(yīng)將路床上的浮土、雜物全部清除，保持表面整潔。此外，還應(yīng)對底基層進(jìn)行徹底清掃，同樣清除浮土、各類雜物及散落材料。

　　2. Cleanliness: Before laying the cement stabilized crushed stone subgrade, all floating soil and debris on the roadbed should be removed to maintain a clean surface. In addition, the subbase should be thoroughly cleaned to remove floating soil, various debris, and scattered materials.

　　3. 翻挖與修補：路床上的車轍、松軟及不符規(guī)定要求的部位均應(yīng)翻挖、清除，并以同類材料修補。修補后的壓實厚度不得小于10cm，并應(yīng)重新整型、碾壓至符合壓實度的要求。

　　3. Excavation and repair: Ruts, soft and non compliant parts on the roadbed should be excavated, removed, and repaired with similar materials. The compacted thickness after repair shall not be less than 10cm, and shall be reshaped and rolled again to meet the requirements of compaction degree.

　　4. 濕潤度：鋪筑水泥穩(wěn)定碎石底基層前，應(yīng)適當(dāng)灑水潤濕路床表面，使其保持一定的濕潤度，有利于混合料的攤鋪和壓實。

　　4. Humidity: Before laying the cement stabilized crushed stone subgrade, the surface of the roadbed should be moistened with water appropriately to maintain a certain degree of humidity, which is beneficial for the paving and compaction of the mixture.

　　基層和底基層正式施工前，均應(yīng)鋪筑試驗段。

　　Before the formal construction of the base and sub base, a trial section should be laid.

　　試驗段應(yīng)設(shè)置在生產(chǎn)路段上，長度宜為200～300m。

　　The experimental section should be set on the production road section, with a length of 200-300m.

　　試驗段開工前，應(yīng)符合下列規(guī)定：

　　Before starting the experimental section, the following regulations should be met:

　　a)提交完整的目標(biāo)配合比報告。

　　a) Submit a complete target mix ratio report.

　　b)生產(chǎn)配合比報告應(yīng)包含生產(chǎn)配合比的調(diào)試結(jié)果，待試驗段驗證后確定最終的生產(chǎn)配合比報告。

　　b) The production mix proportion report should include the debugging results of the production mix proportion, and the final production mix proportion report will be determined after verification by the test section.

　　c)正常施工時所配備的施工機(jī)械完全進(jìn)場，且調(diào)試完畢。

　　c) The construction machinery equipped during normal construction has been fully mobilized and debugged.

　　d)全部施工人員到位。

　　d) All construction personnel are in place.

　　e)編制詳細(xì)的試驗段施工方案，并進(jìn)行技術(shù)交底，施工方案應(yīng)包括原材檢測情況、確定的生產(chǎn) 配合比、施工組織機(jī)構(gòu)組成、擬采用的施工工藝、施工保障措施及現(xiàn)場交通組織措施。

　　e) Develop a detailed construction plan for the test section and conduct technical briefing. The construction plan should include information on raw material testing, determined production mix ratio, composition of construction organization, proposed construction technology, construction guarantee measures, and on-site traffic organization measures.

　　試驗段施工后，應(yīng)及時總結(jié)，總結(jié)報告應(yīng)包括下列內(nèi)容：

　　After the construction of the experimental section, it should be summarized in a timely manner, and the summary report should include the following contents:

　　a) 試驗段檢測報告。

　　a) Test section inspection report.

　　b) 試驗段總體效果評價。

　　b) Overall effectiveness evaluation of the experimental section.

　　c) 施工關(guān)鍵參數(shù)的推薦值，包括配合比、含水率、松鋪系數(shù)、碾壓工藝等。

　　c) Recommended values for key construction parameters, including mix proportion, moisture content, loose paving coefficient, compaction process, etc.

　　d) 針對兩層連續(xù)攤鋪工藝，確定每一作業(yè)段的合適長度。

　　d) Determine the appropriate length for each work section for the two-layer continuous paving process.
