TI  - Evaluation of Stripping Problem in Terms of Additive
Types and Ratios in Asphalt Pavements
AB  - Stripping in asphalt mixtures is the one of foremost distress mechanisms. To prevent
stripping, fatty acids (AS) and hydrated lime (HL) additives are often used as anti-stripping
additives. The determination of the correct usage ratios of these additives and the storage
stability of bitumen constitutes important research topics for anti-stripping additive
applications. Three surfactants and hydrated lime were used in three ratios to evaluate the
effect of additive ratio and type. Indirect tensile strength (ITS) values obtained from samples
with one and three cycle modified Lottman conditioning and indirect tensile strength ratios
(ITSRs) were interpreted in the context of water damage. The load-carrying capacity of the
conditioned mixtures increased significantly. Even if the degree of damage was considerably
increased at the end of three cycles, the integrity of the mixtures was maintained. Both AS
and HL significantly increased water damage resistance. Modified Lottman conditioning has
an observable level of damage. Additives remained functional and maintain their
mechanisms of benefit, especially in the event of a high degree of damage.
