This report describes a New Zealand study of the effect of different binders on the rate of chipseal texture loss under traffic. Work to measure the adhesive and rheological (flow) properties of different binders is described. Several chipseal trials were constructed and seal texture depth development over time was observed. Conclusions are drawn on the choice of sealing binders.
