The Hot Milling Machine
The Hot Milling Machine removes the preheated and softened surface to a depth of 50 mm without crushing the aggregates. This process maintains the original gradation, enabling successful Hot In-Place (HIR) mix designs with 80% recycled content
The Cold Milling Problem
The removal of a cold, hard pavement surface requires maximum horsepower and brute force. This process crushes the existing aggregates during removal, which alters the gradation and limits the average recycled material content in surface pavements to 20%
The Hot Milling Solution
Preheating softens the surface, which eliminates aggregate crushing. The preservation of the original aggregate gradation allows for the creation of new asphalt equivalent HIR pavements that consist of 80% recycled materials and 20% new materials.
