Fine, medium and coarse gradation mixtures for different aggregate types were tested to investigate the effects of variation in the aggregate types and gradation on mix properties. The asphalt contents of the mixes were maintained at the job mix design contents.

  • How is Asphalt Made? A Look Inside the

    2018-9-26 · Asphalt composition is around 5% asphalt cement and 95% aggregate. Asphalt cement is a type of liquid petroleum that works as a glue to bind the aggregate together. Aggregate varies depending on climate and other requirements. Essentially, you could define it as a bunch of small rocks.

  • What is Asphalt Aggregate? (with pictures)

    2021-2-15 · A hot mix asphalt (HMA), which is typically used for roads and parking lots, is as much as 95 percent asphalt aggregate by weight. The majority of aggregate in the mix is usually coarse, or large in size, followed by crushed stone and gravel. The remaining aggregate is composed of fillers, such as sand.
