Cold Recycling of Bituminous Pavement With Foamed Bitumen

Introduction

The global expansion of road infrastructure and its environmental implications underscore the urgent need to prioritize the construction of sustainable and environmentally friendly pavements. In the last few decades, pavement maintenance and rehabilitation have emerged as significant challenges confronting highway agencies. This is particularly because of the acute depletion of raw materials and the increased price of road-building materials (such as bitumen) over the last decade.
