Tracking vehicle movements and having the ability to gain real time data can be very useful when ensuring quality and safety of the build.
The example below demonstrates how one site innovated a technology to achieve this:
- A trial has been carried out and tests taken to confirm the success of the work undertaken to reduce the defects in the road construction;
- This involved combining existing technology to avoid problems and has resulted in moving the technology on to another level to resolve the problem of a ‘cold joint’ being formed when connecting layers of ‘black top’ at different temperatures and weather conditions;
- A GPS system tracks the journey of the ‘black top’ delivery vehicle and constantly records its location and temperature of the material;
- This information is then aligned with the laying machine to optimise the laying process and alleviate the vehicle arriving late and the ‘black top’ being too cold or the laying machine not being available when the delivery is made;
- The trial was carried out using 3 vehicles initially and tests taken to confirm the results which were positive;
- Subsequently the whole motorway (a distance of 6.5Km) was laid using this technique;
- The benefits are that with the data recorded for each batch, it is possible to the extract details of a batch (time, temperature, weather conditions and pressure of the material being laid) should a defect occur;
- Consequently allowing a guarantee for the road surfacing to be longer and a more reliable maintenance schedule established.
