2. WORK TO BE DONE:

Equipments and materials will be used for removal of existing asphalt, preparation and paving as specified here-in. Existing asphalt will be saw cut, removed, and disposed of offsite. Removal and disposal may be done by excavation or grinding the existing asphalt in place. The grindings may be used as part of the base prep for the new asphalt. Existing sub grade shall be graded and compacted as needed. 5/8” or grindings shall be added to the base course where needed to match grade. 2.5 inches of hot mix asphalt production and placement will conform to the 2014 WSDOT Standard Specifications, M41-10 section 5.04. A tack coat of asphalt will be applied to all paved surfaces on which any course of HMA is to be placed or abutted.

The grade of PG asphalt binder to be used is HMA CL. 1/2 IN PG 64-28. All work will conform to the scope of work and the following additional requirements;

a. Saw cut and clean existing pavement edges to allow appropriate bonding.

b. Grade and compact top-course prior to paving.
