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.

The initial investment for constructing a median and guardrails for a prestressed concrete bridge is $1000000. Maintaining these facilities is expected to cost $2000 annually for the first five years of service and $10000 for the next five years of service. It is expected that these facilities will be rehabilitated at the end of the tenth year at a cost of $60000, after which the maintenance costs are expected to decrease to $6000 per year. What is equivalent uniform annual cost over a 15 -year period of service if the interest rate is 6% per year?
At 7.8%, a bridge cost P220M with a life of 18 years. The bridge must be partially rebuilt at a cost if P90M at the end of each 18 years. Calculate the capitalized cost if an annual maintenance of P590,000 is required.

A bridge has been constructed between the mainland and an island. The total cost (excludingtolls) to travel across the bridge is expressed as C = 50 + 0.5V, where V is the number ofveh/hr and C is the cost/veh in pesos. The demand for travel across the bridge is V = 2500 −10C.a. Determine the volume of traffic across the bridge.b. If a toll of 25 pesos is added, what is the volume across the bridge?c. A tollbooth is to be added, thus reducing the travel time to cross the bridge. The new costfunction is C = 50 + 0.2V. Determine the volume of traffic that would cross the bridge.

A county transportation agency has asked you to suggest the allocation of bridge preservation budget of 50 million between Interstate and non-Interstate highway bridges. Political considerations require that urban populations receive at least $25 million in benefits and rural areas at least $10 million. As a rule of thumb, a $1 million investment yields total user benefits of $1.25 million for $1 million spent on Interstate highway bridges $1 million for $1 million spent on non-Interstate highway bridges Your research also indicates that the distribution of benefits for each highway is
