During the cold in-place (or in-situ) recycling process, the reclaimed material does not leave the construction site at all, but is processed on the spot and reused immediately. This not only eliminates the need for trucks to make frequent trips to the processing station, but also reduces construction times.
Low cost and high quality are two of the most important criteria when it comes to rehabilitating roads. The WIRTGEN cold recycling train has yet another advantage: roads can be re-opened to traffic in no time.
An existing pavement when recycled to form a new base or subbase layer by treating the pavement material with bitumen emulsion and cement are termed as BSMs. The quantities of bitumen emulsion added do not typically exceed 3% by mass of aggregate. Active filler in the form of cement is also added to the mix and its content not exceeding more than 1%. Use of emulsion in BSMs enables dispersion preferentially amongst the finer particles. A non continuous binding of the individual aggregate particles makes BSMs different from all other pavement materials. BSMs remain granular in nature and must be processed as such during construction. BlacktopBE emulsions can be made available with On-Demand Custom Chemistry at the project site. Absolutely the right emulsions are first tested and blended with locally available aggregate to develop custom performance solutions, which when laid will develop the exact strength within the desired time lines for time to traffic.
