| Summary: | <align="justify">Pavement condition can be measured by how serious the functional and structural failures occurred. Slippage failure is one of the failures on road pavement which often happens on some location, such as the braking and turning point. This failure caused by the poor bonding between pavement layers.Some researchers believe that this type of failure results from high horizontal stress and insufficient adhesion and bonding at the interface between pavement layers.Extensive research has been conducted on the field concerning pavement materials performances. But only few number researches concerned about bonding conditions between pavement layers and their effects to pavement life. At present, most of flexible pavement design assumes full bonding between pavement layers. But actually in reality, the bonding conditions are in the range between full adhesion and zero adhesion, depends on the property of material and the construction qualities.This study's objective is to identify the effect of bonding condition to pavement structure's responses. there are some pavement structure analysis program that already been used, one of them is BISAR.One of the facilities of this program compared to another program is its capability to input Shear Compliance (AK) value for analyzing stress and strain on multilayers pavement. This value has a strong relation with Shear Modulus (Ks) that represented bonding condition at the interface.Decreasing trend of stress, strain, and deflection at the interface were taken place as the increasing of Shear Modulus (Ks). On thicker pavement structure, the variation of Shear Modulus (Ks) has less effect to the structural responses. In order to increase Ks value, tack coat and prime coat with high adhesion can be applicated, then thinner asphaltic layer can be used.At some locations where the horizontal forces taken place, there is an increasing of tensile strain response. In such a way at those locations, e.g. braking and turning point, thicker asphalt layers are needed and it will be better to consider horizontal force variable for designing pavement on those locations. Structural capacities on study case location were increasing on a better bonding condition (higher Ks values) at the interface between AC-WC and AC-BC. Comparing with the same failure criteria with two different bonding condition, there is a reduction of remaining life until almosr 50% with the aplication of partial bonding condition at the interface.<align="justify"> |
