BLDG $2014$: Assignment $10$

Define the following terms:

a$.$

A$.$ir Voids $($AV$)$

b$.$ Voids in the mineral aggregate $($VMA$)$

c$.$ Voids filled with asphalt $($VFA$)$

An asphait concrete mix contains $2240kg$ of apgregates and $145kg$ of asphait binder per

m$3.$ Asphalt absorption of the apgegates is $1\mathrm{.}2K.$ The bulk relative density of the agpegate

is $2\mathrm{.}68$ and the relative density of the asphalt is $1\mathrm{.}04.$ Find the density, waphalt content $($total$,$

effective, and absarbed$),$ and the air voids, VMA, and VFA.

The following graphs were plotted from the results of a Marshall test. The desien

requirements are light traffic with an aggregate nominal size of $19\mathrm{.}0mm.$

a$.$ Select the optimal asphalt content.

b$.$ Check if the asphalt content you selected will meet the design requirements.
