Abstract: A flowable material for pavement repair and maintenance comprises rounded sand coated with a polymeric 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 polymeric 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.
Abstract: A fuel resistant binder is characterized by the addition of a carrier curing agent to a modified, unmodified or emulsified asphalt material formed of a mixture of hot, cold or emulsified asphalt and carrier and activator materials. The carrier curing agent preferably is a polyurethane moisture curing solution. A cross-linking material and aggregate are also mixed with the binder to form a material suitable for patching cracks and holes in pavement and the like. The activator assists the polymer material in linking with the asphalt while the carrier prevents the formation of gel or lumps within the asphalt. The carrier curing agent resists the penetration of fuel into the binder.
