Automated Data Collection
AGW’s goal is to improve road maintenance and pavement management practices and policies by improving the condition of the street network, or to keep it at the current level, by using more effective resources. This is done by focusing on the following targets:
- Diagnosing paved streets using new non-destructive testing methods
- Changing maintenance policies from reactive to a more proactive approach so the appropriate treatment can be applied before serious pavement distresses appear
- Improving pavement maintenance by applying more adequate and cost-effective techniques
These techniques allow our engineers to focus on repair measures so potential problems can be addressed at the root. AGW’s project team is committed to providing efficient and effective services so the street network can be properly evaluated for future planning.

Ground Penetrating Radar (GPR) – GPR data can be used to interpret existing pavement thicknesses including, asphalt, concrete, underlying base course, pavement irregularities, and subsurface texture and moisture variations using nondestructive means.
Pavement Deflection Testing – AGW owns a falling weight deflectometer (FWD) JILS-20, which is manufactured Foundation Mechanics, Inc. Our FWD machine is calibrated on a yearly basis. We utilize FWD equipment to record pavement deflections used to estimate the structural strength parameters of pavements and the underlying subgrade materials.
Our local experience sets us apart from other out of state consultants. We are more experienced in local practices, materials, and pavement behavior. We work hand in hand with local municipalities to solve pavement maintenance challenges.
