Strategic Alliance Reference Group 5 November 2009 #13 Binders – Sharon Forbes & Russell Spies 3 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

4. Strategic Alliance Reference Group 5 November 2009 #13 Binders – Sharon Forbes & Russell Spies 4 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
