  • Asphalt Concrete Pavement Compaction Testing
  • Asphalt Coring
  • Straightedge Testing


Mobile Laboratories – Mobile laboratories are self-sufficient units set in trailers that are equipped for Soils/Concrete/Asphalt depending on the scope of testing to be performed and on the project site conditions. ACS can outfit a mobile laboratory for any project throughout the state of Arizona.

ACS SERVICES LLC has experience, capacity and capability to set up multiple mobile laboratories and is able to service remote areas.
