Question: While ISSA A 1 6 5 does provide general guidance for aggregate and emulsified asphalt application rate in a chip seal treatment, the ranges provided

While ISSA A165 does provide general guidance for aggregate and emulsified asphalt application
rate in a chip seal treatment, the ranges provided are that only: guidance. However, the actual
application rates are extremely job specific, and may change due to gradation of the aggregate,
traffic, existing road conditions, absorption of aggregate, patches that haven't been sealed, residue
of emulsion, and other inputs. Therefore, it is important to execute an actual chip seal design.
Create and upload a spreadsheet that can calculate the emulsified asphalt quantity, given
the following values:
Quantity of chips from the board test =30lbft2
Dry loose unit weight of chips =104lbft3
Dry bulk specific gravity of chips =2.15
Traffic correction factor = chip seal class I, 251-500 AADT
Pavement surface correction factor = smooth, non-porous
Emulsified asphalt residue =65%
Using the spreadsheet, adjust the following values (as compared to the control design
above) and record the emulsified asphalt quantity. Report the asphalt quantities in a table.
State why the trend you are observing makes sense.
Q=10,20,30,40, and 50
T=1.00,1.05,1.10,1.15,1.20
V=-0.06,-0.03,0.00,+0.03,+0.06
R=0.60,0.65,0.70
