Experiment Research on Key Performance Indexes of Synchronous Gravel Water-Proof Adhesive Layer for Bridge Deck Pavement in Seasonal Frozen Region

Abstract:

Synchronous gravel water-proof adhesive layer has many advantages, and is widely used to bridge deck pavement. Though the material of synchronous gravel water-proof adhesive layer has high temperature sensitivity, it needs more research that whether this construction can well adapt to seasonal frozen region. Used UTM-100 and self-design testing machine, we tested and analysis the key parameters of the water-proof adhesive layer about SBS nature-changing pitch crushed stones, rubber-asphalt synchronous gravel and high-viscosity asphalt synchronous gravel. Firstly, based on result of core testing under normal temperature, I determined the best mix-proportion for three materials, and tested their shear, tensile strength, deformation performance under different temperature and humidity.
