Pavement Services
Frank H. Lehr Associates is ready to
serve your pavement engineering needs from project design through
construction and into service.
Investigation/Design:
Our staff of Professional Engineers can design a subsurface
investigation program to gather the necessary information for a
proper design for your new pavement or to determine the causes and
remedies for existing pavement distress
We are equipped to
perform laboratory and field design testing necessary to provide the
required design information.
Our Engineers review and analyze the
subsurface information, soils testing, and projected traffic
loading, and design a pavement to serve your needs.
Construction:
Our asphalt testing services include monitoring of paving
operations in both the plant and the field. We can provide certified
FAA or NJDOT inspectors, for your paving project.
