Abstract
This invention is a light weight vibration-damping sheet comprising an asphalt binder component, a hollow filler component and a surface treated calcium carbonate treated with a higher fatty acid or its salt, such as aluminum stearate, which acts as a hollow filler dispersion agent. As the hollow filler is dispersed uniformly in the asphalt, the sheet forming workability of the composition is greatly improved.
