The cold in place recycling process has gained recognition and popularity worldwide as a cost-effective means of rehabilitating distressed road pavements. The process requires the use of specially designed recycling machines. The heart of these machines is a large milling drum fitted with tungsten-tipped steel teeth that makes it possible to recycle pavements.
Cold in place recycling consists essentially of milling the existing road pavement to a predetermined depth in order to recover the material that was used in the original construction. This material is then reprocessed, normally with a stabilizing agent, to form a new strengthened pavement layer. This means that it is no longer needed to bring in new aggregates (shell sand, stones and asphalt) from, in the case of Surinam, from a large distance and applied to build a new road.
The product in this case will be a cost effective environmental friendly and sustainable recycled road structure that performs like hot mix asphalt, but without the added energy costs, trucking requirements, or volatile emissions of hot mix asphalt.
The cold in place recycling method leads to 95% less CO2-emmision compared to the traditional road rehabilitation technique.
This pilot project has been established by a Dutch and Surinamese joint venture company. A 50% PSI grant has supported this investment.
