Asphalt coring setup along Beetham Highway
Asphalt Coring - ASTM D5361 Standard Practice for Sampling Compacted Bituminous Mixtures for Laboratory Testing
This test involves the cutting of asphalt cores on site using a combination of a Hilti coring machine, generator and water tank setup on a van. The procedure takes approximately 5 minutes depending on the size of the core and thickness of pavement. Police presence is usually required for the diversion of traffic during testing. The cores are immediately filled using a cement/aggregate mix.
Dynamic Cone Penetration setup – ruler, drive shaft, 8.0 kg weight, drive rod. Requires three persons to use for holding the shaft, operating the hammer and taking readings from the ruler
Dynamic Cone Penetration - ASTM D6951 Standard Test Method for Use of the Dynamic Cone Penetrometer in Shallow Pavement Applications
This test can be used to estimate pavement layers thicknesses and correlated in-situ CBR value. The equipment comprises of a cone tipped drive rod attached to a ruler, which penetrates the ground by applying blows using a sliding 8.0 kg hammer along the drive shaft. The number of blows required to achieve a certain depth of penetration is measured and recorded and plotted for analysis.
Benkelman beam testing along Churchill Roosevelt Highway
Benkelman Beam - ASTM D4695 Standard Guide for General Pavement Deflection Measurements
This setup evaluates the structural capacity of the existing pavement by measuring the deflection of the pavement under moving wheel loads.
