THE PERFORMANCE OF VARIOUS CHIPSEAL TREATMENTS WHEN PLACED OVER A CRACKEDASPHALTIC CONCRETE SURFACE

In March 1983, the Dunedin City Council's Roading Division constructed six trial sections of chipseal on an 1135m length of Hillside Road where cracking of the asphaltic concrete pavement had developed but where the pavement showed only minor distortion. Different sealing binder formulations and treatments were used to enable comparisons to be made regarding the ability of each type of seal and binder to provide attenuation of the reflective cracking which normally occurs in this situation. This paper providesinformation on the construction of each trial section, the various binders used, problems encountered and subsequent observations made. Results ofthe observations are discussed and it is concluded that the use of polymer modified binders with significant elastic properties, when used in conjunction with a two-coat seal, provide a practical and economical surface treatment for a cracked asphaltic concrete pavement which is exhibiting little distortion.
