Abstract
A void filling asphalt emulsion and a method of using the void filling asphalt emulsion to fill voids below the surface of an asphalt pavement. The void filling emulsion is prepared by forming a base asphalt emulsion having about 45 to 75 wt. % of an asphalt content, and combining the base asphalt emulsion with a surface tension reducing solution to produce a void filling asphalt emulsion that has about 25 to 50 wt. % of an asphalt content. When applied to an asphalt pavement the void filling emulsion penetrates into the asphalt pavement and fills voids in the asphalt pavement. The void filling emulation further being water resistant so as not to be washed off a pavement surface by water after being applied to the pavement.
