Gauge Basics. There are currently 5 gauge manufacturers; CPN (recently purchased by InstroTek), Humboldt, InstroTek, Seaman and Troxler, which collectively have more than 20 different gauge models that measure soil, asphalt and concrete density and soil and rooftop moisture. Mechanically, all soils and asphalt moisture density gauges work the same.

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

A critical factor in achieving this density is the ratio of lift thickness to nominal maximum aggregate size (t/NMAS). The information in the report is designed to help make agencies aware of a range of practices other agencies use to achieve a desired t/NMAS ratio, ensuring that density of AC is adequate to meet expected pavement performance.

Bulk asphalt models and confined layer models were used to derive thermodynamic material properties of asphalt binder, including density, surface free energy, cohesive energy density, and solubility parameter. The work of adhesion between asphalt binder and aggregate were derived from interaction energy with different definitions of surface area.

Thus, this paper uses Ground Penetrating Radar (GPR) tests to assess density and moisture content on asphalt mix slabs. Six asphalt mixes were produced in laboratory with the same aggregate gradation and asphalt type, varying the binder content (4.0, 5.0 and 6.0%) and the air-void content (from 3.7% up to 16.9%).

The Troxler Model 3440 Surface Moisture-Density Gauge measures the moisture content, density, and compaction of soils, soil-stone aggregates, concrete, asphalt treated bases, asphalt surfacing, and other materials that approximate similar ranges of density and/or moisture content. Currently recognized as the industry standard for compacting control

Standard asphalt density is 145lbs/ft3 or 2322kg/m3. The asphalt unit weight is 2243 per cubic meter. Therefore 2.4 ton of asphalt = 1 cubic meter. 1 cubic yard of hot asphalt mix weighs 2.025 tons or 4050 lbs. These measurements are an approximation and therefore when you are ordering the quantity ensure that you add more asphalt to gather for ...

Asphalt. Asphalt is produced through the refining of petroleum. It is a viscous adhesive that, along with aggregate, forms HMA pavement surfaces. In this article we will follow the crude oil as it leaves the seagoing tanker at the Marine Terminal at US Oil and Refining Company in Tacoma, WA and becomes asphalt.

density at and around the longitudinal joint. Joint density is normally most important on high-volume roads and airports. The process of creating the highest density at the longitudinal joint is the first topic to be addressed. User Tip: A useful option for some applications is an edge cutter. The edge cutter installs on Asphalt

The desired density is generally specified by the road owner or contracting agency. Coring to measure density Coring is a destructive testing method, which means that the cores are cut and removed from the final product – the in-place asphalt mix. Then they are taken to a lab for density measurement using water displacement.

The purpose of compacting asphalt pavements is to density the asphalt concrete and thereby improve its mechanical properties as well as to provide a watertight segment for the underlying materials in the pavement structure [13]. Asphalt compaction is a densification process during which air voids …

asphalt mix. For example 95% density implies that the pavement is compacted to 95% of its theoretical maximum density or that the pavement has 5% air voids in terms of volume. The density of a roadway core extracted from the completed pavement is also used

The following densities should be used for estimating quantities of Hot Mix Asphalt (HMA) material. Table 1: HMA Densities Material Density Density Values for Scott County Projects Density Values for District 6 HMA 145 pcf — — High Performance Thin Lift Overlay (non-slag mixture) 150 pcf — — High Performance Thin Lift

Achieving desired density is crucial for thin asphalt concrete (AC) overlay construction quality control and quality assurance purposes. Ground penetrating radar (GPR) can be implemented for AC pavement layer thickness and density prediction during compaction. However, the overlapping of GPR reflections from surface and bottom of the thin AC overlay, as well as the presence of surface …

Marshall stability and flow test values, density, and air voids in the mix and the mineral aggregate are all used for evaluation of trial mixtures of lab-mixed, lab-compacted (LMLC) asphalt mixtures. Marshall stability and flow tests can also monitor the production of the asphalt mixture using plant mix, laboratory-compacted (PMLC) samples.

Answer (1 of 3): 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 you are recieving mate...

The radar sensor continuously scans the surface to produce compaction or density maps. Additionally, an integrated temperature sensor generates pavement temperature maps. Temperature differences indicate locations where the asphalt mix is not uniform in terms of temperature or mix (i.e., too little binder, different aggregate, etc.).
