In-place pavement recycling cuts costs and project time
Water-based asphalt recycling technology reduces maintenance expenses and accelerates road repairs, authorities say.
At a glance
- In-place recycling reduces maintenance costs by 26% and project time by 40%
- Water-based process lowers energy use and carbon dioxide emissions
- Four-stage process mills, recycles and relays asphalt in place
- Technology supports road safety and service level goals
The Roads General Authority has deployed in-place pavement recycling equipment that reduces maintenance costs by approximately 26 percent and shortens project timelines by about 40 percent, according to the authority. The technology mills, recycles and relays asphalt using water rather than heat, lowering energy consumption and carbon dioxide emissions while conserving natural resources.
The four-stage process involves milling the top asphalt layer to a depth of 5 to 10 centimetres, mixing it with other materials, relaying and levelling it, then compacting and smoothing for use. The authority said the work supports goals of the Road Sector Program, including reducing road deaths to fewer than five per 100,000 people and bringing the network to International Road Assessment Program safety standards.
Why it matters
The technology supports efforts to improve road safety, reduce maintenance spending and meet international safety standards while lowering environmental impact.
