Explanation of Solution

Difference between tar and asphalt cement as in Table (1):

Asphalt cementTar
Asphalt occurs in natural form or by means of a by-product of petroleum refinery. It is sticky, adhesive, elastic, and easily able to stretch flex and bend without breaking.Tar cannot occur in natural form; it is obtained as a by-product when manufacturing water-gas and coke.
Asphalt is more weather resistant.Tar is more temperature susceptible, usually used to coat aggregates that are more water resistant.
Hot mix paving asphalt creates odor that can be strong and persistent.Tar has an aromatic odor.
Asphalt molecules tend to be aliphatic (referred as a straight chain).Tar tends to be aromatic (referred as cyclic or ring).
Asphalt fume causes health hazards such as skin rash, fatigue, headache, and also skin cancer.Fumes from the heated tar cause health hazards to human beings such as severe eye and skin irritation.

Uses:

They are largely used for pavement construction and maintenance.

It is used as glue with aggregate particles to create the asphalt concrete.

Uses:

They are broadly used in road works because it is superior and also used for preserving timber.

1. For the foundation shown below: Qapp = 60 kips (Load obtained from structural engineer) 1.5 ft G.W.T. 3 ft Poorly Graded Sand (SP): Ym 115 pcf (above G.W.T.) Ysat 125 pcf (below G.W.T.) c' = 0, ' = 35° K Square footing, 4' x 4' Foundation Dimension Information: 1-ft x 1-ft square concrete column. 1-ft thick "foot" flanges. Yconc=150 pcf *Assume weight of reinforcing steel included in unit weight of concrete. *Assume compacted backfill weighs the same as in-situ soil. Assume this foundation is being designed for a warehouse that had a thorough preliminary soil exploration. Using the general bearing capacity equation: a. Calculate the gross applied bearing pressure, the gross ultimate bearing pressure, and determine if the foundation system is safe using a gross bearing capacity ASD approach. Please include the weight of the foundation, the weight of the backfill soil, and the effect of the uplift pressure caused by the presence of the water table in your bearing capacity…
