In a bituminous mix, the percentage by weight of coarse aggregate, fine aggregate, filler, and bituminous binder is 58, 25, 12, and 5, respectively. The corresponding specific grav...

On a two-lane highway, a horizontal curve of radius 300 m is provided. The design speed is 80 km/h. If the longest wheelbase of vehicle expected on this highway is 7 m, then the ex...

A car is travelling at a speed of 60 km/hr on a section of a National Highway having a downward gradient of 2%. The driver of the car suddenly observes a stopped vehicle on the car...

The consolidated data of a spot speed study for a certain stretch of a highway is given in the table. Speed range (kmph) | Number of observations 0 - 10 | 7 10 - 20 | 31 20 - 30 |...

The shape of the most commonly designed highway vertical curve is

A highway designed for 80 km/h speed has a horizontal curve section with radius 250 m. If the design lateral friction is assumed to develop fully, the required super elevation is

The coefficient of average rolling friction of a road is $f_r$, and its grade is +G%. If the grade of this road is doubled, what will be the percentage change in the braking distan...

The speed-density relationship of a highway is given as u = 100 - 0.5 k where, u = speed in km per hour, k = density in vehicles per km. The maximum flow (in vehicles per hour, rou...
