    <subfield code="a">&lt;p&gt;The increasing demands of higher axle loads, speeds and usage means understanding the ballast behavior and its interaction with the infrastructure remains a critical element to the design and successful operation of ballasted railway track, Therefore it is important to study the degradation of ballast to increase and predict ballast life on the track, reduce waste track, keep good track quality and minimize the frequency and cost of ballast replacement.&lt;/p&gt;</subfield>
