Overview• Point of manufacture and point of delivery
sampling and testing requirements clarified• Point of delivery sampling and testing
requirements for asphalt and spray works separated
• Costs for point of delivery sampling and testing to be borne by the Contractor
• Project manager determines compliance point i.e. Point of manufacture vs Point of delivery

Bitumen and PMB Sampling and Testing
• Sampling and testing is to be conducted at BOTH – Point of Release from Manufacture (by
Manufacturer)AND– Point of Delivery (by Contractor)
• The purpose is to establish the effects of any contamination/mishandling during transport

Engineering Note (EN) 07
• Point of delivery limits for PMB’s• Deductions calculated by formula based on
Torsional Recovery and Softening Point field values
• 8½ years of QDMR field data used to determine deductions formula for each grade
• Deduction not to apply until Jan 2011 to allow further data to be consolidated.

MRTS 18 - Polymer Modified Binder Field Testing Requirements
• Field compliance tests changed: Torsional Recovery and Softening Point used instead of Consistency at 60°C
• Initial high frequency of sampling and testing aims to generate data regarding each binder class’s stability during transport, handling and storage
• Sampling and testing frequencies to be revisited when additional data is available
