This book presents the detailed results of five task groups of the
RILEM technical committee TC 237-SIB on Testing and
Characterization of Sustainable Innovative Bituminous Materials and
Systems. It concentrates on specific new topics in asphalt binder
and mixture testing, dealing with new developments in asphalt
testing, in particular also in view of new innovative bituminous
materials, such as hot and cold recycled mixtures, grid reinforced
pavements and recycled Reclaimed Asphalt Pavements (RAP), where
test methods developed for traditional asphalt concrete are not a
priori applicable. The main objective is providing a basis for
pre-standardization by comparing different test methods and showing
ways for fundamental improvements. Thus, the book also points the
way for a further advanced chemo-physical understanding of
materials and their role in pavement systems relying on fundamental
material properties and suitable models for describing and
predicting the intrinsic mechanisms that determine the material
behavior.

This STAR on asphalt materials presents the achievements of RILEM
TC 206 ATB, acquired over many years of interlaboratory tests and
international knowledge exchange. It covers experimental aspects of
bituminous binder fatigue testing; the background on compaction
methods and imaging techniques for characterizing asphalt mixtures
including validation of a new imaging software; it focuses on
experimental questions and analysis tools regarding mechanical
wheel tracking tests, comparing results from different labs and
using finite element techniques. Furthermore, long-term rutting
prediction and evaluation for an Austrian road are discussed,
followed by an extensive analysis and test program on interlayer
bond testing of three different test sections which were
specifically constructed for this purpose. Finally, the key issue
of manufacturing reclaimed hot mix asphalt in the laboratory is
studied and recommendations for laboratory ageing of bituminous
mixtures are given.
This work presents the results of RILEM TC 237-SIB (Testing and
characterization of sustainable innovative bituminous materials and
systems). The papers have been selected for publication after a
rigorous peer review process and will be an invaluable source to
outline and clarify the main directions of present and future
research and standardization for bituminous materials and
pavements. The following topics are covered: - Characterization of
binder-aggregate interaction - Innovative testing of bituminous
binders, additives and modifiers - Durability and aging of asphalt
pavements - Mixture design and compaction analysis -
Environmentally sustainable materials and technologies - Advances
in laboratory characterization of bituminous materials - Modeling
of road materials and pavement performance prediction - Field
measurement and in-situ characterization - Innovative materials for
reinforcement and interlayer systems - Cracking and damage
characterization of asphalt pavements - Recycling and re-use in
road pavements This is the proceedings of the RILEM SIB2015
Symposium (Ancona, Italy, October 7-9, 2015).
