- Please let the A- What are the differences between: answers be short and concise (Planning & Operation, intersection & interchange, Flexible & Rigid Pavement, Well- graded aggregate & Poor-graded aggregate, Tack coat & Prime coat). CS Scanned with CamScannerihal exam II. Identification. Identify the following terms 1. a little covered opening in a floor, pavement, or other surface that allows a person to enter, especially one that leads to a sewer in a city street. 2. The time frame in which the analysis will be carried out 3. is a process that aims to restore the structural effectiveness of the pavement while also providing superior riding and skid resistance. 4. The creation of one or more alternative routes or corridors is included in a broader analysis of the entire area. 5. It is the distance if one track to other. No new data to save.

- URGENT Please answer this problem in 15 minutes, need a correct answer with complete solution. Subject is Highway Engineering. Box the final answer and do not shortcut your solution. I will give an upvote if it satisfies. Thank you! A vehicle that is moving on a wet road that has difference in elevation of 3 m on both ends. Starting point is higher than the end point. The horizontal length of the road is 100 m ends at an initial speed of 50 km/h and is needed to stop. What is its braking distance?What primary types of data are needed for highway bridge deck, superstructure, and substructure condition assessment?Describe why the sightline for electronic distance measurement should be at least 0.5 m off the surface of the pavement along its entire line of sight.
