Automatic is More Accurate

by Asphalt Contractor Staff
Created: April 1, 2005

Automation improves test procedures for determining the bulk specific gravity of fine aggregate.

Incorporates many new features, including more flexible data analysis setup and automation and a completely new test type
New analysis routines have been built into the software, including a new template wizard, improved model fitting capabilities, Time Temperature Superposition (TTS) analysis, and new data manipulation routines
Extended language support with English, French, German and Spanish language versions available as standard, and the capacity for reconfiguration to support most major European languages

Troxler Enhanced RoadReader Plus Model 3451

Troxler Electronic Laboratories has added the Enhanced RoadReader Plus Model 3451 to its line of nuclear moisture density gauges.

Measures moisture and density of soils, aggregate, asphalt and concrete
On-board Global Positioning System (GPS) and a wireless Personal Digital Assistant (PDA) user interface
Density readings can be measured from 2 to 12 inches using the direct transmission method, or 1 to 4 inches with the backscatter method
Moisture readings can be read up to 11 inches from the surface of the test material

EDCO GTM

Engineering Developments Co. offers the gyratory testing machine (GTM), a combination compaction and simple-shear testing machine for use with cylindrical specimens of soils and base course materials as well as asphalt mixes.

Designed so plastic deformation or rutting can be simulated and predicted independently of voids criteria
Determines optimum binder content for a required wheel load service
Provides independent verification of SHRP superpave and other mix design results

Slip Asphalt Depth Gauge

With the asphalt depth gauge from Slip Industries, there's no need to step onto hot asphalt to test asphalt depth or curb height.
