Phase and Interphase Behaviour of Bituminous Materials State-of-the-Art Report of the RILEM TC 272-PIM

This book presents the work of the RILEM Technical Committee 272-PIM on Phase and Interphase behaviour of Bituminous Materials and showcases advances and innovations in the field of bituminous materials for flexible pavements. 

The first section delves into complex and combined binders, unravelling intricate phenomena and shedding light on the unique challenges posed by these materials. Through meticulous cross-testing, the fundamental physical processes are better understood. The second section addresses the low-temperature performance of bituminous mixtures, exploring important behaviour regarding the longevity and resilience of bituminous pavements. The use of innovative methodologies, particularly the restrained shrinkage test exploited using a three-dimensional perspective, enriches the understanding regarding the mechanical behaviour at cold temperatures. The third section delves into dynamic interlayer shear testing, providing a comprehensive guide to evaluate the bonding behaviour of bituminous interlayers under cyclic loadings.

By considering the multiphase nature of road materials and structures, the book not only fills gaps in existing knowledge but also lays the foundation for the development of more durable materials. Its emphasis on a performance-driven and internationally validated approach makes it a reference tool for those contributing to the advancement of sustainable materials in the field of bituminous material engineering.
