A study was done to establish the standard mix design criteria needed for 4.75-mm mixes. On the basis of the findings of the study, the recommended Superpave mix design criteria include a specified gradation control of 30% to 54% passing on the 1.18-mm (No. 16) sieve and 6% to 12% passing the 0.075-mm (No. 200) sieve.

The first fatigue study on hot mix asphalt (HMA) was performed at Nottingham University in the 1950s; since then, a massive amount of work has been done. This paper provides a review survey of fatigue studies of asphalt mixtures; this survey includes demonstrating fatigue test techniques, test modes, load configurations, …
HOT MIX ASPHALT SUMMARY Hydrated lime in hot mix asphalt (HMA) creates multiple benefits. A considerable amount of information exists in the current literature on hydrated lime's ability to control water sensitivity and its well-accepted ability as an antistrip to inhibit moisture damage. However, recent studies demonstrate that lime also
Hot Mix Asphalt is a combination of approximately 95% stone, sand, or gravel bound together by asphalt cement, a product of crude oil. HMA is mixed at high temperatures (around 300 degrees Fahrenheit) in an asphalt plant and then transported to the job site, hence the name "hot mix." It's best known for its durability, resilience, and …
We evaluate the quality of the HMA by setting parameters on these three components, which have historically provided a good indication of a mixture's probable performance. …
