This document provides a framework for specifying a range of characteristics as well as applicable test methods for polymer modified bitumens, which are suitable for use in the construction and maintenance of roads, airfields and other paved areas, together with information on assessment and verification of constancy of performance. Polymer modified bitumen is defined in EN 12597. This document describes the performance for characteristics of polymer modified bitumens, as shown in Table 1 and Table 2. It gives information for Declaration of Performance, selection of the grades, characteristics and test methods. This framework covers the following essential characteristics: - consistency at intermediate service temperature; - consistency at elevated service temperature; - viscoelastic behaviour; - cohesion; - resistance to flow and deformation; - temperature sensitivity; - strain recovery; - durability of strain recovery; - durability of consistency at low service temperature
