Road bridge pavement reinforcement and deck waterproofing GGRW method
Integration of road bridge pavement reinforcement and deck waterproofing work NETIS No. KK-220072-A NEXCO Grade 1 compliant
The reduction in durability of RC road bridges is influenced by the durability of RC slabs and asphalt pavements, which are interrelated factors. Fatigue caused by wheel loads accumulates fatigue in the RC slabs and asphalt pavement surfaces, leading to cracking. The intrusion of rainwater and de-icing agents from these cracks is believed to accelerate the deterioration of the RC road bridge structure. Therefore, the waterproofing effect and durability of slab waterproofing are emphasized. Additionally, the quick release from the public facility of road bridges during renovation work is also an important perspective. The road bridge pavement reinforcement waterproofing system "GGRW Method" developed this time suppresses cracking in the pavement, minimizes damage to the waterproof layer, and allows for quick release. It significantly improves the film strength of conventional asphalt coating waterproof materials and addresses the adhesion issues between resin-based coating waterproof materials and asphalt pavements. A sheet membrane with continuity that integrates waterproofing and reinforcement is created on-site, effectively bonding the pavement and slab with good adhesion to demonstrate its effectiveness in slab waterproofing methods.
