Asphalt Binders and Mixtures

Asphalt binders are subsidiary products procured during the refining process of petroleum while manufacturing gasoline, diesel, and similar petroleum products. Asphalt binders are obtained from the residue that remains after the distillation of petroleum, this residue is further subjected to steam distillation and oxidation to remove the traces of gas oil present in the residue. Certain additives or modifiers are also added to asphalt binders to alter them to suit different applications.

Given four different types of aggregates to be used to produce a blended aggregate for use in the manufacture of asphaltic concrete, determine the bulk specific gravity of the aggregate mix.
Given the specifications for an asphaltic concrete mixture and the results of a sieve analysis, determine the proportion of different aggregates to obtain the required gradation. Coarse aggregates: 60% Fine aggregates: 35% Filler: 5%
In designing reservoirs, the indirect tensile strength of the concrete mix is specified to be less than a specific value (e.g. 2.8N/mm2 ) for potable water. Why should engineers put an upper limit of indirect tensile strength?
The design of a concrete mix requires 1173 kg/m3 of gravel in dry condition, 582 kg/m3 of sand in dry condition, and 157 kg/m3 of free water. The gravel available at the job site has a moisture content of 0.8% and absorption of 1.5% and the available sand has a moisture content of 1.1% and absorption of 1.3%. What are the masses of gravel, sand and water cubic meter that should be used at the job site?
A concrete mix has the following ratio, excluding water, of cement:sand:gravel (3:6:7). How much gravel would be needed in 860 cubic meters of the dry mix? Round your answer to the nearest whole number.
A concrete aggregate mix must contain at least 31% sand by volume for proper batching. One source of material, which has 25% sand and 75% coarse aggregate, sells for $3 per cubic meter (m3). Another source, which has 40% sand and 60% coarse aggregate, sells for $4.40/m3. Determine the least cost per cubic meter of blended aggregates.
For concrete production, we mix 625 kg of fine aggregate and 830 kg of coarse aggregate. The fine aggregate has a moisture content of 2.3% and absorption of 3.2%, whereas the coarse aggregate has a moisture content of 1.5% and absorption of 2.8%. Calculate the amount of water required to increase the moisture contents of both fine and coarse aggregate to reach absorption?
The correct mix for a batch of concrete is 5:4:2 in terms of sand, gravel, and cement. The batch is to have 2200 pounds of these ingredients. How many of each are needed? Sand Gravel Cement
A mix has an aggregate/cement ratio of 6 and a concrete porosity of 17 per cent. Assuming there is no entrapped air, calculate the water/ cement ratio of the mix, given that the specific gravity of aggregate is 2.6 and the degree of hydration is 90 per cent.
