Influence of Handling on the Effectiveness of Antistripping Additives

Report No: 81-R8

Published in 1980

About the report:

The purpose of this investigation was to determine the influence of the procedures used in handling asphalt-additive blends on the effectiveness of antistripping additives in asphaltic concrete. The additives were blended with the asphalt cements before shipment by tank truck to the hot mix plants. Laboratory tests were performed on samples of the asphalt cement obtained prior to the blending process at the terminal and after blending and shipment by tank truck to the hot mix plant. Quick bottle tests and infrared spectrophometer tests were used to determine the presence and approximate amount of additive, respectively. A stripping test was performed to determine the effectiveness of the additive. The results of this limited investigation indicate that the present procedure of blending asphalt and antistripping additive before shipment to the hot mix plant is satisfactory; however, long periods of storage at high temperatures might cause the additive to lose part of its effectiveness.
