Polymer modified binders (PMBs) can provide improved service performance over normal bitumens in demanding situations. However, a number of field problems have been experienced with PMBs and some of these have been attributed to property changes which can occur during storage and transport of a binder to the work site.
The pilot study was undertaken to obtain information on the changes likely to occur in different PMB grades. Such information would be useful in developing guidelines for the handling, storage and use specific to each grade or type of PMB.
