Marshall Method. Although HDOT does not use the Marshall method, it accepts Marshall mix designs. Most private laboratories use the Marshall method because it is a proven method and requires relatively light, portable and inexpensive equipment. Like the Hveem and Superpave methods, the Marshall method has been proven to produce quality HMA from which long-lasting pavements can be constructed. This …
Method (ACI 211.1) Although not the only way to do a quality mix design, the ACI procedure is widely used. The absolute volume method specified by ACI 211.1 consists of 8 steps plus adjustments. The goal of the following example is too show the basic steps and how important minor changes in proportions can be on workability, durability ...
Pavement Design Highway users have an increased awareness of pavement quality. To help agencies and contractors meet the demand for high-quality pavements, NAPA's Asphalt Pavement magazine regularly provides articles that directly address issues such as mix type selection and statistical specifications.
