Concrete Pavements for Climate Resilient Low-Volume Roads in Pacific Island Countries

In pursuit of economic and social development objectives, governments of Pacific Island Countries (PICs) desire to upgrade unpaved low-volume roads (LVRs) for the improvement in connectivity and quality of life associated with all weather-access. W...
