1.1 This test method covers the determination of the relative density and density of semi-solid asphalt binder and soft tar pitches by use of a pycnometer. Note 1: An alternate method for determining the density of asphalt binder is Test Method D3289 .
Liquid Asphalt - ia Asphalt Association
Asphalt (sometimes called "liquid asphalt", "asphalt cement" or "asphalt binder") is a sticky, black and highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product; it is a substance classed as a pitch.

How to Determine Quantities - Asphalt Pavement
To determine the weight of material multiply the volume by the density of material: Weight = Volume × Density Using the previous example and assuming an asphalt pavement mixture density of 145 pounds per cubic foot (pcf) and a thickness of 4" we would perform the following calculations.
Tack Coat Guidelines 1-09 - Caltrans
· Asphalt binder is heated and applied at a much higher temperature than an emulsion. When the ambient temperature is above 85ºF, asphalt binder will easily adhere to
Asphalt Testing Equipment - Gilson Co.
Modern asphalt pavements must resist rutting, thermal variations, high load cycles, hydraulic pressures from water, and more. Testing asphalt for characteristics such as air void content, density, shear strength, stiffness and fatigue resistance provides assurances that this …
SUPERPAVE MIXTURE DESIGN GUIDE
increased asphalt binder stiffness. The stiffer binder locks the aggregate particles in place to prevent rutting. The binder cannot carry the load alone and cannot overcome a poor aggregate skeleton by itself. The final step before selecting the binder grade to be specified is to compare the grade

LTPP Computed Parameter: Dynamic Modulus APPENDIX A: PROCESSING ASPHALT BINDER VISCOSITY DATA A.1 INTRODUCTION. Until the advent of the Superpave™ mix design system in the early 1990s, the viscosity of asphalt binders was the key measure used in purchase specifications.
Improving pavement density | Asphalt magazine
1.5-inch lift, 5.4% asphalt binder = potential 93 to 94 density range = improved pavement density = improved pavement durability Maintenance projects There is a desire to decrease the surface layer thickness on some projects to save initial construction dollars.
Pavement Manual: Hot-Mix Asphalt Pavement Mixtures
Optimum asphalt binder content is derived by molding specimens at various binder contents, plotting the asphalt vs. density curve and selecting the binder content that corresponds to the specified target laboratory molded density.

Asphalt Pavement Thickness and Mix Design - Asphalt ...
By specifying a density requirement, the voids are inversely controlled. Keep in mind that density is a relative term, compared to a target density of either lab compacted mix, a maximum theoretical density, or a control strip density. ... As the asphalt binder wears way from the surface with traffic, the color of the aggregate is exposed.

Compaction - Hawaii Asphalt Paving Industry
This expression of density is easy to convert to air voids because any volume that is not asphalt binder or aggregate is assumed to be air. For example, a density reported as 93 percent Rice means that there are 7 percent air voids ( - 93% = 7%).
Unit Weight of Asphaltic Concrete | Garden Guides
Asphalt concrete -- also known as asphaltic concrete -- is a mixture of gravel or aggregate with crude oil residue to serve as a binder. Although asphalt concrete is the technical name, laypeople typically refer to this mixture as asphalt.
