SiteTesting

DGL Testing Services offer convenient on-site testing services performed by our team of expert Materials Testing Technicians who are equipped with the necessary equipment to provide independent assessment at your project site. Our Technicians work seamlessly with your team to ensure minimal disruption to your operations while delivering reliable testing results in real-time.

Aggregates

Bituminous Mixtures

We offer a comprehensive range of services to ensure the quality and integrity of construction materials and pavement surfaces. Our skilled technicians specialise in various sampling techniques, including meticulously hand-sampling fine and coarse aggregates from stockpiles. Additionally, we employ sample reduction methods using riffle boxes to ensure representative samples for analysis. We understand the importance of precise temperature control in bituminous mixtures, so we offer services to measure temperatures in laid materials and paver hoppers. Our expertise extends to sampling workable materials around paver augers and coring heaps of laid and compacted materials for thorough analysis.

Assessment of in-situ density of materials include:

Soils

We offer a comprehensive suite of in-situ density testing methods tailored to your project needs. These include:

Sand replacement method using both small and large pouring cylinders.
Core cutter method for precise density determination.
In-situ bulk density testing using nuclear methods, encompassing absolute and compliance tests.
In-situ moisture density testing, employing nuclear methods for accurate assessments.
Determining soil vertical deformation and strength characteristics through plate loading tests and equivalent CBR plate bearing tests.
Lightweight dynamic plate testing using a lightweight deflectometer (LWD), dynamic cone penetrometer test (DCP), and hand-held shear van tests (HSV) for comprehensive soil.

Coring

We provide comprehensive coring services using Xcalibre T4 and T5 coring rigs. Our extensive range of coring services can be customised to meet the unique requirements of each client.

The coring process begins with the extraction of core samples from the pavement. These samples are then analysed to identify the bituminous materials present. One critical aspect of our analysis is the investigation for coal tar, that requires precise detection and management.

Our advanced equipment and experienced team ensure that we deliver accurate and reliable results, helping our clients maintain the highest standards in road construction and safety.
