Chapter 4: Construction Details, Section 39: Asphalt Concrete - How much does density matter? | Asphalt magazine

The normal target in-place density on a "dense" hot-mix asphalt pavement is 92 to 93 percent of Gmm (or 7 to 8 percent air voids). If a pavement has low density (usually defined as less than 92 percent of Gmm), the air voids are interconnected and premature pavement distresses can result.Density of bitumen/asphalt can be measured in accordance with the ASTM D70 or EN15326 test methods, or the newer ASTM D8188. A digital density meter helps to determine the density of bitumen more easily via the newer method. ... ASTM D8188 is a more recent standard test …

Standard spec 460 sets forth the specifications for required densities and establishes reduced payment schedules for pavements deficient in density. Regardless of reduced payments the intent is to achieve the required density. Section 460 requires that the contractor not operate below the specified minimum density on a continuing basis.Answer (1 of 6): 2400kg per cubic metre is a good generic density. Sorry if you use the imperical system, I'm sure you can convert it easy enough. In real life though, it's a good idea to calibrate this figure based on tonnage used, average depth and coverage, especially if …

Asphalt pavement density measurements were made using a conventional nuclear density gauge and a new type of non-destructive density meter called the "Pavement Quality Indicator." Five sets of density tests were made at each of the nine sites during, or immediately following paving operations between July and September, 2004.• "Standard"Density (ADOT) • Effective Voids at 5.5% (4.5% for Superpave) • In-Place Air Voids at 7.0% (max 9.0%) • Problem: • Not all pavements in Arizona experience these high temperature extremes. • It does rain on occasion. And it snows. Is Increased Density appropriate for hot, low elevation regions of the Desert Southwest?
