The bonding between asphalt and aggregate is of special importance because it is the primary characteristic that influences the integrity of pavement, This bonding must be established at the initial stage of contact between the asphalt and the initial stage of contact between the asphalt and the aggregate and must endure during the life time of the pavement. Loss of bonding results in lowered performance. The pavement strength is attributed to (1) cohesive resistance of the binder (2) the adhesive bond between the binder and the aggregate, (3) the aggregate Inter lock and the frictional resistance between aggregate particles. A number of different methods have been used to strengthen the adhesion of asphalt to aggregate and to lower the pavements propensity to strip, deformation and aging from the intrusion of moisture.When incorporated into the binder , Kavassu Antistrip promotes chemical adhesion between the binder and the aggregate and promotes adhesion of the binder to the road surface be it wet or dry. When Kavassu Antistrip is dissolved in the binder, it arranges itself so that it is attached to the stone on the one hand and the binder on the order , thus ensuring complete contact with the binder, it is important that the viscosity of the binder is sufficiently low as to enable the Kavassu Antistripto move to the stone surface and this is always achieved at normal spraying or coating temperatures. It can be seen therefore, that coating chips with a solution of adhesion agent is not the most effective and economical way of applying adhesion agents . The treated binder method ensures that the Kavassu Antistrip can orientate itself at the two interfaces, i.e, aggregate/ binder and binder/road surface, thus ensuring maximum chemical adhesion at both . An obsolete method of applying adhesion agents to surface dressing was to sprinkle a solution of the agent on the binder before appli- cation of the aggregate. This method, apart from being inaccurate and laborious, suffered from the disadvantage of not providing adhesion at the road/binder interface. If Kavassu Antistrip is to function efficiently as a binder additive, the binder must not be too viscous or the movement of the Kavassu Antistrip molecules will be impeded. Correct spraying and mixing temperatures will ensure that viscosity promotes maximum efficiency.
