890.1GENERAL REQUIREMENTS
Transporting conveyances for asphalt material will be free of contaminating material. A record of material hauled the previous load in truck transport tanks will be furnished as a prerequisite to loading. A determination will be made if the previously hauled material is compatible with the material to be loaded or if cleaning of the tank is required to prevent contamination. All sampling will be performed in accordance with SD 301. If the material is to be used prior to testing by the Department, the asphalt material supplier will furnish two copies of a Certificate of Compliance for each tank car, truck tank, or other individual conveyance. The Certificate of Compliance will show all information contained on Form DOT-62 and a properly executed certification statement. Temperatures to provide kinematic viscosities of 300 centistokes and 150 centistokes for mixing application and 200 centistokes and 50 centistokes for spray application will be furnished with the first load of each type of asphalt material delivered to the project on or along with the Certificate of Compliance. Upon presentation of a Certificate of Compliance, the Engineer may permit incorporation into the work the asphalt material covered by the certificate. Permission by the Engineer to use asphalt material will not be construed as an acceptance of the material. Acceptance of asphalt material will be based on test results from the samples obtained. Asphalt material tested and accepted for use on a project and transferred by the Contractor to another project, may be accepted for use in the terminating project on the basis of the test results of the originating project. The Contractor must request and receive from the Engineer of the originating project, prior to transfer, a letter of transfer covering the material. (DOT-70)
