DENSITY OF ASPHALT CONCRETE - HOW MUCH IS NEEDED?

DENSITY OF ASPHALT CONCRETE - HOW MUCH IS NEEDED? E. Ray Brown INTRODUCTION Background The amount of voids in an asphalt mixture is probably the single most important factor that affects performance throughout the life of an asphalt pavement. The voids are primarily controlled by asphalt content, compactive effort during construction, and additional compaction under traffic. The density

Asphalt concrete - Wikipedia

Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth century.

Properties of Asphalt Concrete -

Asphalt concrete differs from other bituminous-mineral materials, with higher density, strength and water resistance. These properties are achieved by the application of a special mineral powder and precise portioning of all components. One of the important advantages of asphalt concrete is its ability to be used in construction of automobile roads of almost any category, including roads with

DENSITY OF ASPHALT CONCRETE - HOW

Density is one of the most important parameters in construction of asphalt mixtures. A mixture that is properly designed and compacted will contain enough air voids to prevent rutting due to plastic flow but low enough air voids to prevent permeability of air and water. Since density of an asphalt mixture varies throughout its life the voids must be low enough initially to prevent permeability

Accurate Density Determination of Asphalt

A recent comparison of the ASTM D70-09 method and the AccuPyc II TEC to determine the density of four different asphalt samples showed only a 0.003% to 0.026% difference between the two sets of results 7. This shows that the AccuPyc II TEC can provide a much easier and rapid analytical method for the asphalt industry.
