Introduction
Core Technology Innovation of the Standard
| Technical Indicators | Requirements of this Standard | Comparison with Traditional Standards | Technical Advantages |
|---|---|---|---|
| Asphalt Saturation | ≥150% | 80-120% | More Complete Impregnation |
| Base Material | Waste spun fiber | Polyester felt/glass fiber felt | Environmentally friendly and renewable |
| Seam Peel Strength | ≥1.5N/mm | 1.0N/mm | Stronger deformation resistance |
Key performance analysis
1. Waste spinning base characteristics
The patented technology (201711341972.7) is used to transform waste clothing into 430-450g/m² fiber felt. Tests show that:
- Fiber mixing ratio: cotton spinning ≥40%, chemical fiber ≤50%, leather ≤10%
- Longitudinal breaking tensile force ≥1300N/50mm, transverse ≥1200N/50mm
- Weather resistance test passed 150 cycles from -60℃ to 40℃ without cracks
2. Self-adhesive layer technology
According to the requirements of GB/T 23260-2009:
Application case of an underground project in Beijing: During construction, the self-adhesive layer of the roll forms a "skin-like" bond with the base layer, maintaining a complete waterproof layer when the building settles 3mm, saving 30% of the energy consumption of traditional hot-melt construction.
Implementation suggestions
- Selection guidance: Mineral aggregate (M) type is used for exposed roofs, and fine sand (S) type is used for underground projects
- Construction points: Construction should be carried out when the ambient temperature is ≥5℃, the overlap width should be maintained at 100mm, and additional sealing treatment should be required at the joints
- Acceptance criteria: Focus on testing the soluble matter content (≥3300g/m²) and 70℃ heat resistance index
Standard evolution analysis
Compared with GB 18242-2008 elastomer modified asphalt standard, the innovation of this standard is reflected in:
- New waste textile base technology system (patent 201711341967.6)
- Introduction of 150 hot and cold cycle weathering test method
- High requirement for the peel strength of the self-adhesive layer after immersion in water is ≥1.5N/mm
