塑膠跑道瀝青基礎技術要求介紹

來源:http://66975.cn/ 日期:2023-10-21
膠跑道瀝青砼基礎必須符合體育設施驗收標準、《瀝青路面施工及驗收規(guī)范》(GB50092)和塑膠層施工工藝技術要求:
The asphalt concrete foundation of the rubber track must comply with the acceptance standards for sports facilities, the "Code for Construction and Acceptance of Asphalt Pavements" (GB50092), and the technical requirements for the construction process of the plastic layer:
1.基底采用8-12噸壓路機碾壓數(shù)遍。壓實度應大于95%,碾壓后表面無輪跡印,不得出現(xiàn)松軟、彈簧等現(xiàn)象。
1. The base is compacted several times using an 8-12 ton roller. The compaction degree should be greater than 95%, and there should be no wheel marks on the surface after rolling, and there should be no looseness, spring or other phenomena.
2.瀝青材料質量標準:
2. Quality standards for asphalt materials:
針入度(1/10)>60:軟化點》50?C;延伸>100;含蠟量≤3%.
Penetration (1/10)>60: Softening point>50? C; Extension>100; Wax content ≤ 3%
濟南瀝青料
3.瀝青混凝土結構
3. Asphalt concrete structure
上面層為30mm厚AC-10細粒式瀝青混凝土;下面層為50mm厚AC-20中粗粒式瀝青混凝土。
The upper layer is 30mm thick AC-10 fine-grained asphalt concrete; The lower layer is 50mm thick AC-20 medium coarse grained asphalt concrete.
瀝青混凝土的配合比應有實驗室《公路瀝青路面施工技術規(guī)范》要求的方法確定,必須符合馬歇爾實驗
The mix proportion of asphalt concrete should be determined by the method required by the laboratory's "Technical Specification for Construction of Highway Asphalt Pavements" and must comply with Marshall's experiment
各項技術標準和較佳瀝青用量要求,級配合理,舉杯良好的施工性能。
Various technical standards and requirements for optimal asphalt dosage, reasonable grading, and good construction performance.
瀝青混凝土施工時應配備足夠的施工機械,要求采用進口攤鋪機。在施工的各個環(huán)節(jié)中要特別注意不同的溫度控制要求,以保證壓實度達到規(guī)定標準。
During the construction of asphalt concrete, sufficient construction machinery should be equipped and imported pavers are required. Special attention should be paid to different temperature control requirements in various stages of construction to ensure that the compaction meets the specified standards.
4.瀝青面層驗收標準:
4. Acceptance standards for asphalt surface layer:
(1)壓實度大于97%、平整度(3米直尺)誤差小于13mm。
(1) The compaction degree is greater than 97%, and the flatness error (3 meter straight edge) is less than 13mm.
(2)表面整潔,粘結牢固,不得有碾壓車輪印記、裂紋、蜂窩麻面、油包及油污。
(2) The surface should be clean, firmly bonded, and free from roller marks, cracks, honeycomb pits, oil pockets, and oil stains.
5.塑膠跑道橫向坡度不大于0.8%、縱向坡度不大于0.1%;塑膠球場排水坡度宜為0.3%。
5. The lateral slope of the plastic runway shall not exceed 0.8%, and the longitudinal slope shall not exceed 0.1%; The drainage slope of the plastic court should be 0.3%.
