Hierarchy of construction documents (least to most) Standard drawings, Standard specs, Supplemental specs, Plans, Special provisions,
Special provisions copied notes
Which construction documents details approved additions and Supplemental specs
revisions to the standard spec
This ensures an adequate bond between the existing pavement Tack coat
surface and the new asphalt overlay so that slippage and
delamination do not occur
Which tack coat can be used prior to May and after Conventional
September?
Which tack coat can be used year round, and must be used Trackless
from May through September?
What is the range of proper tack coat application? (in .05 to .10
gal/yd^2)
Proper tack coat will leave a residual asphalt cement content .04 to .06
ranging from approximately...? (in gal/yd^2)
Most asphalt emulsions contain __% to __% residual asphalt 60, 65
cement
Most asphalt emulsions contain __% to __% water 35, 40
When is a prime tack coat required? When required by the contract
What could cause poor bonding on an asphalt overlay on a dirt, dust, scabbing
milled pavement?
Air blowing the surface, dampening/flushing surface with clean a milled surface
water, and sweeping with mechanical broom can all be used
to.....
This truck delivers mix directly into the hopper of the paver End dump truck
This truck employs a conveyor belt in the bottom of the truck Live bottom truck
bed to discharge asphalt mix
This allows the paver to be operated almost continuously when MTV
a continuous supply of mix is available from the asphalt plant
This eliminates the problem of haul trucks bumping into the MTV
paver and segregation
