Bituminous material failing the requirements of the tests hereinafter prescribed shall be subject to the provisions of Subsection Bituminous materials that cannot be tested by any of the specified test procedures due to the inherent nature of the material will be assessed 21 demerits. For asphalt cements, demerits will be assessed on a prorated basis on the difference between the LIMIT WITH TOLERANCE and the REJECTION LlMlT. For cutback asphalts and emulsified asphalts, demerits will be assessed for each increment of noncompliance. Demerit values will be rounded down to the nearest whole demerit Gontractor's Responsibility. When shipment of materials arrive on the project after normal working hours, give notice suffìciently in advance to allow arrangements for an inspector to be present when the material is sampled. PHYSICAL PROPERTIES AND TESTS Bill of Lading and Gertificate of Compliance. A bill of lading and certificate of compliance shall be submitted for every load of bituminous material. The bill of lading shall include the following data: 1. Date of shipment and shipping point. 2. Car initials and number of truck transport delivery ticket number. 3. Destination and consignee. 4.
