Proven technology: BW 211 D-40 SL

Best result, high productivity, less fuel consumption

The BW 211 D-40 SL single drum roller is setting new standards in soil compaction. All the expertise and experience have been channeled into the development of the “-40” series. The result says it all: efficient technology and low running costs. In combination with the ECONOMIZER technology, the BW 211 D-40 SL sets new standards regarding efficiency, performance, and productivity.

The results

Results Test Site 1: Semarang – Demak Toll Road

  • 2 lanes of 20m length were set up for the trials. A CBR test was taken after each pass
  • The CBR results after each pass were higher than the ones of the competitor’s roller, indicating a better overall compaction performance of the BW 211 D-40 SL.
  • Based on the standard operating conditions, the SL roller also showed higher productivity and less fuel consumption.
     

Test Site 2: Kertajati Airport Toll Road

  • 2 lanes of 20m length were set up for the trials. A CBR test was taken after each pass, the density was measured after the final pass.
  • The CBR increase was more consistent across all passes compared with the competitor’s machine, which indicated a high deviation across all passes.
  • The BW 211 D-40 SL also achieved a higher final density than the competitor´s machine.

The ECONOMIZER advantage

The ECONOMIZER readings and CBR results showed a possible reduction of the number of passes by about 50%. This means a higher productivity and less fuel consumption.

ECONOMIZER: Continuous compaction

BOMAG ECONOMIZER shows the operator when optimum compaction has been achieved and makes soil and asphalt compaction transparent and efficient.
