|Title:||Effects of amino antistrip additives on stripping of bituminous mixes||Authors:||Ramaswamy, S.D.
|Issue Date:||May-1990||Citation:||Ramaswamy, S.D.,Low, E.W. (1990-05). Effects of amino antistrip additives on stripping of bituminous mixes. Highways and transportation 37 (5) : 9-10, 12. ScholarBank@NUS Repository.||Abstract:||Stripping is the breaking of the adhesive bond between the aggregate surface and the bitumen in a bituminous pavement or mixture. In many cases the stripping problem can be minimised by the use of antistrip additive. The investigation was carried out to evaluate the effect of two types of amino additives on the stripping resistance of bituminous mix due to environmental factors by means of Immersion Marshall Stability tests and qualitative stripping assessment. Core and fresh samples obtained from trial section were conditioned in a simulation model before subjecting to testing. The retained stability values of the additive-treated samples were found to be consistently higher than that of the control mix. From the laboratory and field investigations, the use of amino additives in bituminous mixes is found to effectively increase the stripping resistance.||Source Title:||Highways and transportation||URI:||http://scholarbank.nus.edu.sg/handle/10635/65502||ISSN:||02656868|
