The application status of waterproof bonding material of bridge deck pavement According to the survey of waterproof bonding material types which have been used on expressway in recent years, the most common materials are modified emulsified asphalt, hot modified asphalt and APP coils.
Study on the performance of synchronization gravel waterproof bond layer Synchronization gravel technology means adopt synchronous macadam car spray the macadam and bonding materials on the pavement simultaneously, then use wheel roller roll to form the synchronization asphalt gravel seal coat.
Fig.3 The shear and tensile strengths of different asphalt materials The figure 3 shows that the material types have a great impact to bond performance of waterproof bond layer, the optimal material is SBS modified asphalt, it is more suitable for waterproof bond layer of bridge deck pavement.
