The laboratory shall be equipped with all testing equipment necessary to Testing perform these tests. The asphalt manufacturer shall operate and maintain Equipment the equipment in good condition in accordance with NATA requirements. Asphalt shall be tested for the properties and at the testing frequency Testing shown in Specification 201 QUALITY SYSTEMS. Tests to be undertaken Requirements include: Routine Testing Full Test – PSD & Bitumen Content (WA 730.1) Maximum Dry Density of Asphalt Rice Method (WA 732.2) Bulk Density & Void Content of Asphalt (WA 733.1) Stability and flow of Asphalt Marshall Method (WA 731.1) Routine Testing Partial Test – PSD & Bitumen Content (WA 730.1) Maximum Dry Density of Asphalt Rice Method (WA 732.2) Periodic Testing Moisture Content (AS/NZS 2891.10 or T660) Uniform Coating of Binder (AS/NZS 2891.11) Stripping Potential of Asphalt - Tensile Strength Ratio Test (AG:PT/T232) using freeze/thaw conditioning. – Asphalt shall be sampled in accordance with WA 701.1 with samples Sample testing tested immediately they are taken. The number of tests undertaken shall frequency be evenly spread across the entire period of production for each asphalt mix being tested within a shift. The first sample of asphalt in a shift shall be taken from the first 50 tonnes First sample of asphalt manufactured in the shift for each type of mix being manufactured. If the result of any test sample does not conform to any specified requirements another sample of asphalt shall be taken immediately and tested immediately for a Full Test. For the Stripping Potential of Asphalt - Tensile Strength Ratio, test Preparation of specimens shall be compacted at the site testing laboratory prepared TSR without reheating of the test sample or test portion. After preparation of Specimens the test specimens the Stripping Potential of Asphalt - Tensile Strength Ratio test may be completed in the site laboratory or another laboratory away from the site of the asphalt plant. Results of testing, except for TSR, shall be reported on a NATA endorsed Reporting test report within 24 hours of a sample being taken. The testing laboratory shall send all results directly to, amongst others, the Contractor, the Superintendent and a nominated representative at the Main Roads Materials Engineering Branch. 510.36 NON-CONFORMANCE
