Update of double/double design for Austroads sprayed seal design method

This document is an update of the design procedure for double/double sprayed seal surfacing. The information supersedes that in Update of the Austroads Sprayed Seal Design Method, and replaces Sections 6, 7 and 8 in that document. These are based on the philosophy of filling voids in the aggregate matrix with binder to a depth of about one half to two thirds the height of the aggregate when lying on its least dimension. Adjustments and allowances are incorporated in the procedures to cater for aggregate shape, traffic level, embedment, existing surface texture, hardness of existing surfaces and absorption of binder by either aggregates or the existing substrate. The design procedures cover double/double seals with Class 170 bitumen, Class 320 bitumen, multigrade binder, polymer modified binder and emulsions. A preliminary sprayed seal selection table is also included.
