Asphalt 101: An Introduction to Hot Mix Asphalt

Anchor: #i1013899 Section 6: Hot-Mix Asphalt Pavement Mixtures Anchor: #i1013905 6.1 General. Hot-mix asphalt (HMA) is a generic term that includes many different types of mixtures of aggregate and asphalt cement (binder) produced at elevated temperatures (generally between 300-350ºF) in an asphalt

The Superpave mix design method was designed to replace the Hveem and Marshall methods. The volumetric analysis common to the Hveem and Marshall methods provides the basis for the Superpave mix design method. The Superpave system ties asphalt binder and aggregate selection into the mix design process, and considers traffic and climate as well.

8. Choose an asphalt size and thickness. The size of the aggregate used to create asphalt pavement ranges from 1/2 inch to 3/4 inch (1.27 cm to 1.9 cm). Smaller aggregate is usually used for residential driveways because it gives a smoother appearance. If the aggregate is larger, however, the pavement is stronger.

The effects of sampling strategies and size on statistically based decision making in hot-mix asphalt (HMA) construction are presented. For sample sizes agreed upon by the agency and the contractor, an acceptable level for an HMA mix parameter is determined

Widely used for its convenience, hot mix asphalt is the most common used flexible pavement in the US. It is also known as blacktop or bitumen, and sometimes just hot mix. Hot mix pavements are classified mainly as dense-graded mixes, stone matrix mixes, and open-graded hot mix asphalt. There are also other types of asphalt but are limited to

necessary to complete the construction of hot mix asphalt concrete pavement consisting of one or more courses on a previously prepared base, seal coat of asphalt cement and cover aggregate, and bituminous surface treatment in single or multiple courses. Article 1.2 Applicable Standards
