Abatech
has been awarded a contract for quality control of the MatCon
cap installation at the Hanford nuclear reservation in the
State of Washington, USA. The work includes 1)
evaluation of base properties using deflection testing, 2)
mechanistic calculations of design life, 3) supervision of the
asphalt production and 4) lay-down quality control. This
site protects a series of underground storage tanks which are
potentially leaking contaminants into the ground water system
at the site. The protective cap will minimize this while
the tanks and remediated. |
