  HMA Pavement – Pavement Interactive

  HMA. In certain situations where high base stiffness is desired, base courses can be constructed using a variety of HMA mixes. In relation to surface course HMA mixes, base course mixes usually contain larger maximum aggregate sizes, are more open graded and are subject to more lenient specifications. Figure 4.

  Fatigue Behavior of Fiber-Reinforced Recycled Aggregate Base Course ...

  199951 · An experimental investigation was undertaken to study the flexural fatigue behavior of a stabilized fiber-reinforced pavement base course material composed largely of recycled concrete aggregate with small amounts of portland cement and fly ash. The primary objectives of this endeavor were (1) to evaluate the fatigue resistance of this material; and …

  9.4.2 Base Course. The base course, which lies below the surface course of the pavement, may consist of crushed stone, crushed slag is often regarded as the most important structural layer of a pavement. This course ensures efficient distribution of the traffic load and enables adequate sub-surface drainage.
