In near future, the R&D division will be able to carry out Slope stability, soft ground & landslide designs through a special geotechnical unit that is to be established.
R&D Division is capable of carrying out all the necessary field investigation by its own well-experienced staff through its laboratories. This includes test pit investigation, Benkelman Beam Deflection survey &, etc. Also, the FWD surveying facility is available through the Planning Division, RDA
Not only that, the R&D Division is providing solutions to the road failures throughout Sri Lanka by undertaking the relevant investigations.
Research & Development Division is the main division that provides the pavement designs (Both flexible & Rigid) for the major roads in Sri Lanka.
Pavement design is the major component in road construction. Nearly one-third or one-half of the total cost of construction is related to pavement design, so careful consideration should be taken in the design of pavement. We are undertaking pavement designs for
- New construction
- Pavement rehabilitation works
- Pavement Overlaying
Currently, we are in the process of implementing Mechanical – Empirical Pavement design guidelines to the road designing process.
