FWD and all that it can do for you
HWA offers non-destructive pavement evaluation, subgrade assessment and moduli back calculation; in addition to advanced laboratory characterization of subgrade and subbase materials. HWA provides data and engineering services for the design of PCC, HMA and permeable pavement systems for residential, industrial, and airport use.
Field services include: non-destructive pavement evaluation using our Heavy-Weight Falling Weight Deflectometer (FWD) to assess remaining pavement life; develop data for back calculation of in-situ layer moduli; detect voids and soft subgrade; assess the joint load transfer ability of PCC panels; and develop data for pavement management, reconstruction, and overlay design. Laboratory services include soil classifications (ASTM and AASHTO), Resilient Modulus (MR), and CBR determinations.
