Research into Aperture Parameters of Point-Bonded Waterproof Layers
In this paper the requirements for resistance to cracking and wind suction of waterproof layers are studied. According to the data obtained by practical measurement, a rheological model of Chinese asphalt felt was constructed. The paper presents a general method to determine aperture parameters of perforated asphalt felt and a feasible way to extend the free deformation length. The value of aperture parameters of Chinese perforated asphalt felt is given.
