History of asphalt mix design in North America, Part 1

This asphalt was quite soft and was used in the role of penetrating macadam, in which it was sprayed on top of compacted open-graded aggregate, or it was used by mixing with gravel and making an oil mix In the 1920s, oil mix made with cutback asphalt was a common method of paving.

Get Back to Basics with Asphalt Specimen Prep

Testing poor quality specimens generates misleading results, which is a waste of valuable time and resourc Sample preparation is particularly crucial when testing non-homogenous and non-uniform material such as asphalt mix, thus specimens should ideally match pavement conditions in the field.

Pavement Manual: Hot-Mix Asphalt Pavement Mixtures

Anchor: #i1013899 Section 6: Hot-Mix Asphalt Pavement Mixtures Anchor: #i1013905 61 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.

Asphalt Binder

The mix using the SBS-modified asphalt binder has similar shear strength as the mix using the Pen 30 asphalt binder, but with a lower cohesion value and higher internal friction angle value In summary, using a high-viscosity base asphalt binder or an SBS-modified binder can improve the shear strength of the asphalt mix.

Effects of Laboratory Specimen Preparation on Aggregate

The main objective of asphalt-aggregate mix laboratory specimen preparation is to duplicate, as closely as possible, compacted mix in the field Earlier research (1,2) indicates that gyratory, rolling wheel, and kneading compaction produce specimens with signifi­ cantly different permanent deformation responses to repeated shear.
