Several chemical antistripping additives were used in field installations and compared to a similar installation using hydrated lime. A previous field study of 12 pavements revealed considerable stripping in the surface layers of mixtures placed in Evaluation of the use of antistripping additives in asphaltic concrete mixtures Author: G. W Maupin. This test method can be used to test asphalt concrete mixtures in conjunction with mixture design testing to determine the potential for moisture damage, to determine whether or not an antistripping additive is effective, and to determine what dosage of an additive is needed to maximize the effectiveness. This test method can also be used to test mixtures produced in plants to determine.
The problem can be mitigated by using antistripping additives. Spent sands from nonferrous foundries and foundry baghouse dust can contain a high concentration of heavy metals that could preclude their use as an aggregate in pavement construction. PERFORMANCE RECORD. The commercial use of spent foundry sand in the United States is extremely. However, the utilization of the hydrated lime and liquid antistripping agents (ASA) in WMA mixture makes these issues more complicated. The objective of this study was to investigate and evaluate the moisture susceptibility of the mixtures containing ASA and WMA additives.
Virginia has struggled with stripping of asphalt mixes since the s. Initially, chemical antistripping additives were used; eventually, hydrated lime was required, under certain conditions, when it proved to be effective in a limited set of field by: 3.

use of antistripping additives in asphaltic concrete mixtures: field evaluation The long-term general objective of this research is to provide information on the selection and use of antistripping additives which are materials used to improve the asphalt-aggregate adhesion in asphalt concrete.
requires the use of antistripping additives in all asphalt concrete. Antistripping additives can be either hydrated lime that is applied directly to the aggregate or chemical amine additives that are blended with the asphalt cement.
Chemical additives can be blended with the asphalt cement at. Two widely-used asphalt concrete mixture performance tests (the AASHTO T and the asphalt pavement analyzer under water) and two mixture constituent tests (the boiling water test and the pull-off tensile strength test) are conducted to characterize the effects of anti-stripping additives on the binder–aggregate bonding potential in by: Fig.

MATERIALS AND METHODS In order to evaluate the effectiveness of additives in the mixtures of asphalt concrete, a series of experiments according to the codes of ASTM and AASHTO must be.
TESTING OF ASPHALT CONCRETE FOR EFFECTIVENESS OF ANTISTRIPPING ADDITIVES (WITH DISCUSSION) The project advisory panel for NVHRP Project "Use of Antistripping Additives in Asphalt Concrete Mixtures," requested that a procedure for testing additive effectiveness be selected or developed using equipment readily available to highway by: 1.

ITEM ASPHALT ANTISTRIPPING AGENTS Description. This Item shall govern for furnishing and incorporating lime or liquid antistripping agents in the production of asphaltic concrete pavement mixtures and/or asphalt stabilized base mixtures.
Materials. (1) Lime. The lime shall meet the requirements of Item"Lime and Lime Slurry".File Size: 14KB. HOT MIX ASPHALT ADDITIVES. Liquid anti-stripping asphalt additives or adhesion promoters are chemicals added to asphalt to improve aggregate coating and increase the strength and frequency of chemical bonding between asphalt and aggregate.
The increased bonding strength provides pavements with defense against moisture damage destruction, when.
