Trial pits
TRL are able to carry out trial pits in paved and unpaved areas to collect bulk samples for laboratory testing or enable in-situ tests to be conducted.
Topographical Survey
TRL have the in-house capability to undertake topographical surveys alongside our other works.
RVI
TRL can undertake targeted remote visual inspection surveys to enable viewing of areas with limited access. Typically this includes looking within and behind concrete elements to determine the as-built construction and current condition detail.
Sand patch / pendulum
TRL are accredited to undertake sand patch and pendulum slip resistance testing on site and in the laboratory. We have previously undertaken testing on a range of surfaces from highways to car parks to bus floors.
Unbound Material Sampling (UMS - Window Samples)
Unbound Material are granular materials such as crushed stone, slag, concrete or slate that a road is built upon.
TRL’s Unbound Material Sampler (UMS) provides window samples or boreholes of unbound material underneath the pavement surface.
Used in ground investigation surveys, the UMS will identify the thickness and material of each layer in addition to the depth of any water present. Soil samples can be collected to assess the risk of contamination due to asbestos, metals and other dangerous chemicals and elements.
LiDAR
TRL were one of the first organisations in UK to mount a LiDAR system on a vehicle platform.
SmartSCAN
TRL can provide access to a Breuckmann SmartSCAN 3D camera to support and further enhance your pavement investigations.
The 3D camera takes a 1m x 1m 3D image of the pavement surface. Pavement texture cannot always be determined by texture lasers and for some of our customers, insight into pavement texture is a key requirement of their pavement investigation. The 3D camera can provide this.
Mostly utilised for concrete materials, the 3D camera can be used for all pavement materials.
Surface Condition
TRL are actively engaged in the research and development of surface condition parameters for the network level assessment contract. We have built and operate the TRACS reference machine and provide accreditation and quality assurance support for the delivery of the survey contract.
TSD
TRL have been working with Highways England for over ten years to establish the traffic speed deflectometer as a network level structural assessment tool. This is an area of ongoing research and we currently support HE in the management of the survey contract and accrediting and quality assuring the data.
Skid Resistance
TRL maintain and operate Highways England skid resistance equipment (GripTester, Pavement Friction Tester and Sideways-force Coefficient Routine Inspection Machine (SCRIM), CTM- Circular Texture Meter, Werner-Schultze machine known as Friction after Polishing machine). We are engaged in research in this area and our experts in the field of vehicle validation run the annual skid resistance accreditation trials for other similar operating organisations in the UK.
Test Track Acoustic Assessment & Noise Monitoring
TRL can undertake test track acoustic assessment following BS ISO 10844:2014 and 1994, Acoustics — Specification, for measuring noise emitted by road vehicles and their tyres.
TRL also provide on-going environmental monitoring services for noise and air quality. This involves establishing monitoring systems pre, during and post construction, allowing scheme level benefits to be assessed and demonstrated.
