Shear loads are generated by vehicles braking, accelerating, and turning and must be transferred from the paving system to the waterproofing system and from there to the structural deck. These shear loads are particularly significant on structures such as highway bridges where heavy traffic...

This method, known in the industry as “lap-shear” is much less time intensive than actual pipe joint preparation, and in theory, provides...
