A highway being designed to AASHTO guidelines with a 70 mph design speed, and at one section, an equal tangent vertical curve must be designed to connect grades of +1% and -2%. If the grades intersect at station 100+00, determine the stationing of the PVC, PVT and curve high point for the minimum curve length based pn SSD requirements.

Please define superelevation by referring the forces acting on a vehicle while travelling on the curvature. List the methods of implementation of superelevation and draw cross sections and profiles of each application showing the inside edge, centerline and outside edge of the carriageway.

Draw a typical cross section for a two-lane highway and explain the principal components.

There is many types of compactors and rollers used in the construction of flexible pavement. mention all the types of those rollers and compactor and what are the differences between them and why each type is used for. Take in consideration the effect of changing in the bitumen viscosity with the decrease in the mix temperature during construction.

I need new answer please

Vehicles begin to arrive at a parking lot at 6:00am at a rate of 8 per minute. Due to an

accident on the access highway, no vehicles arrive from 6:20 to 6:30am. From

6:30am on, vehicles arrive at the rate of two per minute. The parking lot attendant

processes incoming vehicles (collects parking fees) at the rate of four per minute

throughout the day. Assuming D/D/1 queuing, draw a queuing (arrival-departure)

diagram to present the events described and determine total vehicle delay.

Can you write more clearly? If it is not clear, some symbols I may not know.

Thank you!

4. The Los Angles abrasion test is applied to natural aggregate particles used in construction of pavements. Is it true? Justify your answer.

5. Discuss the effect of the number of revolutions of the rotating drum used in the Los Angeles abrasion test on the Los Angeles value.

6. A test group A used 11 steel balls while another test group B used 9 steel balls for conducting the Los Angeles abrasion test of aggregates. Compare the Los Angles values obtained by these two groups in terms of percentage difference

1. How does the toughness of road aggregates differ from their compressive strength? Can you write a mathematical relationship, if any?
2. A test group of the class used an old aggregate impact test machine. The weight of the hammer was about 1 kgf lower than the standard weight. Determine the percentage error in the impact value of the aggregate.
3. Should a poor quality road aggregate give a low impact value? Justify your answer.
