Kerosene content estimation

Published: | Category: Specifications , Chipsealing | Audiences: Road traffic engineers & consultants, Roading contractors

This method is a procedure for calculating the lighting kerosene content of cutback bitumen. This method applies to cutback bitumens manufactured from bitumen, Automotive Gas Oil (AGO) and kerosene complying with the M/1 Roading Bitumens specification, including up to 1.5 pph of adhesion agent. Materials containing rheology modifiers, such as polymer modified bitumen, cannot be analysed using this procedure.

Adhesion agents
