1. Importance of Pavement and Bridge Deck Waterproofing & Crack Prevention‌
Rapid socio-economic development has intensified traffic volume and overloaded vehicles, causing pavement/bridge deck cracking and water seepage. This leads to critical issues like concrete corrosion, surface spalling, deck end fragmentation, and void formation. Water infiltration accelerates structural deterioration, severely compromising load-bearing capacity while undermining safety and longevity. Implementing robust waterproofing and anti-cracking systems is therefore essential for infrastructure integrity.
‌2. Material Selection for Pavement/Bridge Deck Waterproofing & Crack Control‌
Polyester fiberglass cloth and filter-composite geogrids are recommended for highway crack prevention.
