Abstract: A flowable material for pavement repair and maintenance comprises rounded sand coated with a polymer surfactant to be non absorbent of water in the presence of a polymer mix which allows time for easy placement of the mix into damaged pavement. The polymer surfactant coating creates a strong affinity between the sand and the polymer mix. The materials are chosen preferably to cause an isoviscous reaction to occur. This type of reaction is characterized by a setting phase which stabilizes the repair before a rapid change in viscosity occurs and may be further enabled by an excess of polymer to increase flowability. An excess of polymer insures that sufficient binder remains at the upper portions of the repair to provide flexible and waterproof structure while excess fluid components settle to the bottom of the repair before setting occurs to seal the surrounding pavement. The slow buildup of viscosity allows the sand to settle so that the mix becomes self-compacting.
