Appendix E Guidance to Field Application of PMBs and Multigrade Bitumens

Modified binders and multigrade bitumens are generally handled and applied similarly to C170 bitumen using conventional sprayed sealing equipment but require increased attention to detail and special consideration of the field construction practices to ensure satisfactory adhesion between the binder and the aggregate.

If using a particular class of PMB or multigrade bitumen for the first time, it is advisable to check with the manufacturer about any special handling or application requirements.
