1.1 DESCRIPTION

###  

A.  History: All three projects are of similar condition, with existing
    asphalt pavement that is 25 to 50 years old with varying amounts of

    to mill and remove existing asphalt; Repair sub-surface failures by
    placement of Geotextile fabric and added base; Install additional
    new drainage and repair existing damaged man-hole drains and set at
    proper elevation to remove surface and sub-surface water; Construct
    additional road width, to 2 fish tank access roads; Place New Hot
    Bituminous Asphalt to all surfaces specified on the plans.

C.  All work shall be performed in strict accordance with the Standard
    Specifications for Roads and Bridges, Washington State Department of
    Transportation 2008 edition. Plans identify all work required for
    the three projects.
