Quality Control of Cationic Emulsion Modified Cold Mix

Several ambitious road construction plans and activities primarily involve bituminous pavements with hot mix technology. Hot mix technology which is a conventional method for road construction, has structurally satisfied the performance requirements over many years. The procedures generally followed by the hot mix technology are : heating of binder and aggregate, mixing, tack coating, laying of mix followed by the compaction process everything done at high temperature in a range of 120ºC to 165ºC temperature. So, it is desirable to find out a suitable alternative for hot mix technology. In India almost 90 percent road network is occupied by bituminous pavements only. Certain limitations associated with use of hot mix asphalt are like emission of greenhouse gases from it, shut down of plants during rainy season, problems in maintaining the paving temperature when hauling distances are more, etc.
