DENSITY PROFILING OF ASPHALT PAVEMENTS - CDOT

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.

Making the case. For example, an asphalt overlay constructed to 93 percent density might be expected to last 20 years while the exact same asphalt overlay constructed to 92 percent density would only be expected to last 18 years. This additional two years of service life translates into significant savings over the long run to a highway agency.

Bituminous Mixtures Laboratory Overview | FHWA

Laboratory PurposeThe Bituminous Mixtures Laboratory (BML) specializes in the research of asphalt pavement mixtures. This laboratory supports the Federal Highway Administration's (FHWA’s) efforts to develop, evaluate, and improve materials, mixture design technology, and performance-based tests for asphalt paving mixtures. The Laboratory's activities are aimed at extending the

Specifying and Measuring Asphalt Pavement Density to ...

TRB's National Cooperative Highway Research Program (NCHRP) Research Report 856: Specifying and Measuring Asphalt Pavement Density to Ensure Pavement Performance examines the current state of knowledge and existing agency practices to measure and specify the in-place density of asphalt pavements.

Optimizing In-Place Density of Asphalt Pavements …

compaction and optimizing in-place pavement density are imperative to achieve high-quality, longer-lasting pavement structures. Most DOTs specify asphalt pavement to be constructed at a minimum in-place density at 91 to 92.5% of its theoretical maximum density. However, it has been shown that with proper techniques,

Asphalt Pavement Thickness and Mix Design - Asphalt ...

Mix and Thickness Design. The maximum unit weight is also sometimes called the “solid density”. This value is based on the asphalt mixture’s maximum specific gravity – also known as the Rice value or G mm in Superpave. The maximum unit weight is determined by multiplying the Rice value by 62.4 pounds per cubic foot (PCF).

Hot Mix Asphalt Concrete Density, Bulk Specific Gravity ...

In 1993, Superior Performing Asphalt Pavement (Superpave) was introduced as a part of Strategic Highway Research Program (SHRP). With the adopting of Superpave mix design system, hot mix asphalt (HMA) pavements have been produced with coarser gradation than previously used mix design methods.

factor that affects pavement performance is the density of the hot-mix asphalt layers that constitute the overall pavement system. If an asphalt layer’s density is too low, there are several damaging phenomenon that can occur. In past studies, low densities have been correlated with high permeability, which can lead to several problems, including
