Road, Rail & Bridge Infrastructure

Pavement distress takes place as a result of increasing traffic loading conditions, variations in ambient temperature, moisture movement and variations in sub-grade preparation during the construction of the pavement matrix. These defects manifest as surface defects and deformation, cracking patterns, and potholes.

STATS believes in providing a clear and concise investigation approach to enable suitable repair methodologies to be implemented. To achieve this, STATS offers the following services:

  • Design for new road and airport pavements
  • Design for upgrading and/or widening of existing roads, airport runways and runway forecourt apron areas
  • Recommendations on drainage, groundwater, onsite or offsite stormwater discharge
  • Evaluation of pavement layer thickness using direct coring/dipping work
  • Evaluation of pavement layer thickness non destructively using Ground Penetrating Radar
  • Estimation of the pavement strength for the various pavement layer components through sampling and laboratory tests or incorporating Falling Weight Deflectometer tests
  • Determination of appropriate rehabilitation and pavement strengthening measures

For concrete bridge assessment, STATS provides the following solutions for our Client:

  • Establish Engineering parameters for existing¬† bridge elements, comprising of Strength and Durability Assessment for reconstruction design
  • Conduct non destructive concrete tests such as Rebound Hammer, Ultrasonic Pulse Velocity, Half Cell Potential and Concrete Resistivity tests
  • Determine the presence of any Alkali Silica Reaction and Alkali Aggregate Reaction issues for the concrete medium
  • Establish the extent of Carbonation Attacks, Sulphate Attacks and Dissolution issues
  • Recommendations on suitable methods of repair and strengthening
  • Recommendations on suitable repair materials to be used
