Effect of Bonding Layer and Admixtures on Performance of Ultra Thin White Topping

Abstract

Traditionally, Cement concrete has been perceived as a material for newpavement construction, in particular for streets with heavy axle loads. However, with respect to pavement rehabilitation, agencies many a times consider bituminous overlays as the first option, regardless of the condition of the existing pavement structure. It is in this environment that Ultra-Thin White Topping (UTW) gaining popularity. The urban streets exhibit well stabilized base due to the repeated wheel load applications, but the riding quality of these streets are not satisfactory due to the deterioration of the surface layer, hence it is required to rehabilitate these pavements. At present these pavement are being rehabilitated with a bituminous overlay frequently, which is causing hindrance and delay to the traffic and the road user. To overcome this it is advisable to rehabilitate these pavement sections with such rehabilitating methods which will not require repeated maintenance and also provide the road user a better riding quality for a long duration of time. The bond between the new concrete and existing bituminous pavement plays an important role in exhibiting composite action, which will lead to better performance of UTW. This paper highlights the effect of different admixtures in concrete on the bond strength between the bituminous layer and a new cement concrete layer.
