Abstract
A dry formulation for an integrated marking material for concrete and asphalt application comprises a cementitious mixture including a hydraulic or cementitious binder, a redispersible polymeric cement modifier, a retroreflective agent filler, and optionally, a reflective agent filler. The formulation preferably includes a pigment, aggregate, a dispersant, a plasticizer, and/or a water reducer. The formulation optionally includes at least one admixture selected from an accelerator, an air entrainer, a defoamer, fibers, an inert filler, a natural clay, a pozzolanic filler, a retarder, a rheology modifier, a shrinkage compensating agent, a synthetic clay, a suspending agent, and a thickening agent. The marking material, when applied, has broadcast onto and embedded into its surface, additional retroreflective agents.

A dry formulation for an integrated retroreflective marking, coating or topping material for concrete or asphalt applications comprising a cementitious mixture including a hydraulic or cementitious binder, a dry redispersible polymeric cement modifier, a retroreflective agent filler, said retroreflective agent filler having a surface coating of an adhesion promoter, and optionally, a reflective agent filler.
A dry formulation for a cementitious marking, coating or topping material for concrete or asphalt, compatabilized for accepting retroreflective agents comprising a cementitious mixture including a hydraulic or cementitious binder, a retroreflective agent filler, said retroreflective agent filler having a surface coating of an adhesion promoter, and a dry redispersible polymeric cement modifier, wherein the binder is selected from the group consisting of portland cement, high alumina cement, calcium aluminate cement, calciumsulfoaluminate cement, activated fly ash, activated clay, and slag cement.
A cementitious marking, coating or topping material for concrete or asphalt applications prepared substantially onsite from a mixture of water with a dry formulation comprising a cementitious mixture including a hydraulic or cementitious binder, a retroreflective agent filler, said retroreflective agent filler having a surface coating of an adhesion promoter, and a dry redispersible polymeric cement modifier, said marking material having retroreflective agents both integrally contained and at least partially embedded in its surface.
A dry formulation for an integrated retroreflective marking, coating or topping material for concrete or asphalt applications consisting essentially of a mixture including a hydraulic binder of at least one of magnesium phosphate cement and magnesium potassium phosphate cement, a retroreflective agent filler, and optionally, a reflective agent filler, and further optionally at least one additive selected from the group consisting of accelerators, air entrainers, defoamers, fibers, inert fillers, natural clays, pozzolanic fillers, retarders, rheology modifiers, shrinkage compensating agents, synthetic clays, suspending agents, thickening agents, adhesion promoters, antistatic agents, and mixtures thereof.
An integrated retroreflective marking, coating or topping material for concrete or asphalt applications consisting essentially of a surface including a hydraulic binder of at least one of magnesium phosphate cement and magnesium potassium phosphate cement, having an at least partially embedded broadcast of retroreflective agent particles having a topsize of at least about 600 microns at the surface, and optionally, reflective agent particles, and further optionally, at least one additive selected from the group consisting of accelerators, air entrainers, defoamers, fibers, inert fillers, natural clays, pozzolanic fillers, retarders, rheology modifiers, shrinkage compensating agents, synthetic clays, suspending agents, thickening agents, pigments, aggregates, adhesion promoters, antistatic agents, and mixtures thereof.
An integrated, retroreflective, cementitious coating or topping material for concrete or asphalt marking applications, prepared substantially onsite from a mixture of water with a dry formulation comprising a hydraulic or cementitious binder, aggregate, a pigment, a retroreflective agent filler and a dry redispersible polymeric cement modifier to form a cementitious mixture;
- said cementitious mixture further including a defoamer, a shrinkage compensating agent, at least one of an accelerator and a retarder, and at least one of a dispersant, a plasticizer or a water reducer;
- said retroreflective agent filler having a surface treatment of an adhesion promoter and optionally a moisture proof, antistatic agent;
- said marking material having retroreflective agents both integrally contained and at least partially embedded in its surface.
