Can we identify the performance of paved assets with respect to structural condition? Can we determine how many years usage we have left or what maintenance interventions and overlays could be used to prolong the life of flexible pavements? Construction monitoring solutions are key, and we operate the largest fleet of accredited Dynatest FWD’s in the UK!
Falling Weight Deflectometer (FWD) is a non-destructive technique used to assess the structural capacity and performance of pavements by measuring their deflection under a load. Data is also vital to determining if the structural capacity of a new pavement is fit for purpose during the design phase. We operate:
- 3 x Heavy Weight Deflectometers – applying a test load in the range of 30 – 240kN
- 1 x Falling Weight Deflectometer – applying a test load in the range of 30 – 120kN
- 1 x Fast Falling Weight Deflectometer – the FastFWD is an accelerated version of the traditional FWD, designed to apply loads up to 5x quicker per drop cycle, enabling real-time simulation of long-term traffic affects. XAIS-PTS operate the only FastFWD in the UK!
FWD benefits and applications include:
- Assess the remaining life of the pavement and assess the impact of increasing road volumes, traffic types or load capacities on the future life and quality of the pavement
- Evaluate pavement rehabilitation and overlay requirements
- Report layer moduli (stiffness), deflection, curvature and sub-grade CBR
- Conduct ‘whole of life’ and economic cost benefit analysis of alternate pavement designs
- Provide quality assurance assessment of recent works against design life criteria
- Complete joint sealing evaluation
- Undertake void detection
