<p>The present invention relates to various methods of making polymeric materials (such as polymeric aggregate particles, polymeric liquid and or finely graded polymeric materials, etc. individually or collectively) -containing ionic functionalities and bitumen-containing ionic functionalities, based on using oxidising agents. The functionalised polymer material, particles or liquid and the functionalised bitumen can then be chemically bonded using a certain cross-linking agent. The final product is suitable for, for example, the surfaces for city streets, highways, airfields, for making base course and any layer in the structure of flexible and rigid pavements for airports, highways and other applications, waterproofing surfacing materials, school play grounds, play ground arid surfacing materials, roof surfacing materials and other construction applications. Polymers are chemical compounds built from large number of atoms. They are therefore of high and low molecular weight. Polymers can be of natural origin (e.g. cellulose, protein, natural rubber and plastic) or they may be synthetically produced (e.g. poly (ethylene), nylon, silicones). The particulate material defined above is suitable for use in construction comprising; modified polymers particles bonded to a modified or unmodified bitumen with or without the aid of curing agent (cross-linking agent), modified bitumen or binder contains modified polymeric materials with or without the aid of curing agent (cross-linking agent), unmodified bitumen or binder contains modified polymeric materials with or without the aid of curing agent (crosslinking agent), modified bitumen bonded to unmodified polymers particles or to unmodified polymeric materials (such as liquid or finely graded polymeric materials) with or with out the aid of curing agent( cross-linking agent) . Wherein said final product mixed with or bonded to pre-coated or uncoated aggregate particles (natural, artificial and crushed aggregates) or any other construction materials. The said final products also can be used in different industrial application with or with out mixed with other materials. The said modified polymers include all type of rubber and plastic materials including recycled, materials. The said modified polymers particles, modified polymeric bitumen, modified polymeric binders can be modified with the chemical mentioned in this patent application in one stage or multi stage applications prior to the mixing with other materials such as the modified or umnodified bitumen binders at both cold or hot mixing process at any temperature range between +OC° to +500C° . The modified bitumen or emulsions can be modified further as described in this application with adding 0.1 % to 30 % Sulphuric acid (or any oxidising agent or binder) by weight of bitumen and or any binder used in the process of producing the final products. The modified rubber and plastic aggregates or products can be pre-mixed with bitumen and or the binder before adding them to the rest of the bituminous mixture contents which normally consists of Asphalt binder (or any other binder with or without additives in cold or hot mixing environments), aggregates & fine mater</p> |
