Modifiers have been used to improve the performance of asphalt/aggregate
mixtures for building roads for over the past hundred years and during
that time the industry has evolved into a sophisticated sector that is
heavily regulated by national and European standards.
The modifiers
used take many different forms: polymers, latex, and many chemical
additives. Determining how modifiers actually affect the performance of a
mixture and establishing construction quality control procedures for
these modifiers can be extremely difficult. In the past these
difficulties have caused many specifying agencies to avoid the use of
mixture modifiers when they could be of benefit to the performance of
the road.
This review explores the type of polymers used in
asphalt, why they are used, where they are used in terms of applications
and the benefits they offer to industry and the road user. In
particular, the reader will understand how polymers can be used to
enhance the functionality of asphalt, that is to overcome deterioration
mechanisms by enhancing asphalt stiffness or flexibility, or by making
it more resistant to deformation (rutting) caused by traffic.
This
review of polymers in asphalt is supported by an indexed section
containing several hundred key references and abstracts selected from
the Polymer Library. It is aimed at anyone who has an interest in
polymers and their highway applications.
