Cutback Asphalt is manufactured by blending asphalt cement with a petroleum solvent. There are three major types of Cutback Asphalt based on the relative evaporation of the solvent: Rapid-Curing (RC), Medium-Curing (MC) and Slow-Curing (SC). Rapid-Curing Cutback Asphalt is used primarily for surface treatments and tack coat.

Emulsified asphalt is simply a suspension of small asphalt cement globules in water, which is assisted by an emulsifying agent (such as soap). The emulsifying agent assists by imparting an electrical charge to the surface of the asphalt cement globules so that they do not coalesce (Roberts et al., 1996 [1]).Emulsions are used because they effectively reduce asphalt viscosity for lower ...

asphalt cement. Liquid asphalts, either cutbacks or emulsions, are simply modifications of asphalt cements to permit use under conditions not suitable for the basic cement. For many applications, however, more than one type or grade may be used, and in some cases choice of the proper material or materials makes the problem confusing.

In general, asphalt cement should be modified to achieve the following types of improvements (Roberts et al., 1996): (i) lower stiffness (or viscosity) at the high temperatures associated with construction which facilitates pumping of the liquid asphalt binder as well as mixing and compaction of asphalt mix; (ii) higher stiffness at high ...

Asphalt, commonly known as blacktop or pavement, is a material mixture of aggregates bound together with liquid asphalt cement that is installed in layers or "lifts", then compacted for a wide array of applications such as roads and parking lots. There are many different types of asphalt including hot or cold mix, Binder or wearing-course mix ...

An asphalt emulsion is liquid asphalt cement emulsified in water. It is composed of asphalt, water and an emulsifying agent. The emulsifying agent is sometimes called the surfactant, which is composed of large molecules. These soap molecules are like tadpoles, having a hydrocarbon tail soluble in liquid asphalt and an electrically charged or ...

In the course of the air-blowing process, asphalt will be heated to around 500°F. After then, air bubbles are pressured into the liquid over many hours; this ensures the asphalt remains in a liquid condition when cooled. Types of asphalt mixes. The different types of asphalt mixes are as follows: Course Graded Asphalt; Porous Asphalt; Milled ...

The mixes in each category will vary based on the size of aggregate in the composition as well as the asphalt cement (liquid asphalt) or binder used. T oday, VDOT has three common families for their mixes – dense graded asphalt, gap-graded (stone matrix asphalt), and open-graded asphalt.

proper design. These parameters include the type of liquid asphalt which,in all but the most unusual circumstances should be PG 64-22;the compaction level should be "N Design 50"or Level 1 for all applications except minor or principal arterial streets. The next two parameters go hand in hand and should always be considered together.
