Road Science has been working with the Hamilton City Council/Downer Infrastructure Alliance recently to make improvements to the roads in Hamilton. Projects have been using Road Science's Enviro Base Bitumen Emulsion. This product stabilizes the base course layer to improve the long-term waterproofness of the roads. Emulsion is mixed into the base course using Downer’s Wirtgen Stabilizing machine this hoes the subsurface and injects the emulsion directly. This machine is directly fed from a Road Science emulsion tanker. The use of bitumen emulsion for this process means the crews are working with products that are safe to handle. They are applied at ambient temperatures, compared with the alternative process using 180C bitumen (for foam bitumen stabilization). The Road Science process also eliminates the need to have a water cart hooked to the stabilizing machine. Feedback from the alliance - “the roads that have used this product are standing up really well!”
This product has been designed for NZ pavement conditions. The operational staff have commented on how well it compacts and can be left unsealed with minimal damage. This method also eliminates the need for the use of cement

2yAnd how do you control the Moisture Content of the finished product without hooking up a water cart?
