PDF Designing Asphalt Pavements for Extreme Climates

States present a unique challenge for hot mix asphalt (HMA) pavements and can lead to accelerated aging of the asphalt binder. Reese and Predoehl observed that the viscosity of the base asphalt may increase by a factor of 40 within 2 to· 4 years (1). This aging causes the pavement to embrittle and consequently to fatigue crack (2).
