Stone Matrix Asphalt (SMA) was originally developed in Europe as an impervious/highly durable wearing surface for bridge decks. Based on its performance history, “splittmastixasphalt†began to be used as a surface layer for roadways carrying heavy truck traffic throughout Germany and other European countries. Today, it is the “pavement surface of choice†where long term performance and durability is needed. The highway traffic in India is increasing at a faster rate with the population and the road network has also expanded in different regions of India. Apart from the increase in truck traffic, there is also a huge difference in the maximum and minimum temperatures of the country. The maximum air temperature can reach even 50˚°C in some parts of the country and the resulting pavement temperature can reach up to 60˚°C. With the increase in loading and temperatures, the pavements are subjected to various types of distresses. Rutting has been observed to be a major distress in flexible pavements and several studies were carried out across the globe to quantify mechanisms of rutting and to reduce the effective rut depth along the wheel path. The United Kingdom is currently resurfacing most all of its heavy traffic roadways with a SMA-type surface to provide a cost-effective surface treatment. Many countries are taking advantage of the quiet and smooth ride characteristics to address the public requirements
