級(jí)配碎石墊層技術(shù)交底.doc

交底內(nèi)容：
1. 本工程基層施工厚度為15cm。
2. 路基準(zhǔn)備：
（1） 在鋪筑基層前，應(yīng)從填筑好的路基上將所有浮土、雜物清除干凈，并嚴(yán)格整型和壓實(shí)使其符合設(shè)計(jì)圖紙要求。
（2） 路床表面上的車轍或松軟部分和壓實(shí)不足的地方以及任何不符合規(guī)定要求的表面都應(yīng)翻松、清除或摻填同類材料重新進(jìn)行整修碾壓。
（3） 施工前對路基進(jìn)行復(fù)驗(yàn)，同時(shí)保證路基排水設(shè)施的完好。
（4） 恢復(fù)中線測量：直線段每20～25m設(shè)一樁，平曲線每10～15m設(shè)一樁。
3. 攤鋪：
分層平行攤鋪，每層鋪設(shè)的寬度，應(yīng)超出路堤的設(shè)計(jì)寬度300mm，以保證修整

1. The base construction projects thickness 15cm.
2. Subgrade Preparation:
(1) in the pavement before the grass-roots level, should be a good foundation will be filling all the surface dust, debris cleared away, and strictly cosmetic and compaction to meet the design requirements of the drawings.
(2) Road bed surface rutting or soft parts and compaction deficiencies and does not meet the requirements of any surface should be turned loose, clear or mixed with similar material to re-fill repair RCC.
(3) before the construction of the roadbed for retesting, while ensuring good subgrade drainage.
(4) restoration of midline measurement: 20 ~ 25m straight line set up one of each, every 10 ~ 15m horizontal curve set 1.
3. Paving:
Hierarchical parallel paving, the width of each floor laying, should go beyond the width of embankment design 300mm, to ensure that repair
