Assessment criteria
Lecture
Written tests consists of 4 questions. Questions are rated by the teacher on a scale 2,0-3,0-3,5-4,0-4,5-5,0. A necessary condition for passing the tests is to assess the minimum 3.0. Final assessment: 3.0 (from 12 to 13 points.), 3.5 (from 13.5 to 14.5 points.), 4.0 (from 15 to 16 points), 4.5 (from 16.5 to 18pkt.), 5.0 (from 18.5 to 20 points).
The tests must be passed without the use of materials and assistance and without communicating with other people. The tests takes about 60 minutes.
Exercise Design:
The assessment of adequate (3.0), the student:
One calculates correctly traffic category in the reference period.
2 Calculates properly design fatigue life of the road surface or pavement strengthening.
3 Place the properly designed pavement construction or reinforcement methods and mechanistic directory. He knows the technical parameters of structural layers in the road surface.
The assessment of good (4.0), the student:
4 Meets the requirements of paragraphs 1-3.
5 Can the construction of pavement design directory methods in complex soil and water conditions, and correctly apply an additional layer of filtration and valve.
6 He can design a structure or pavement strengthening mechanistic methods in complex soil and water conditions, and correctly apply an additional layer of filtration and valve.
For a very good student (5.0):
Meets 7 points 1-6.
8 He can design a structure or pavement strengthening mechanistic methods using methods SPDM or LCPC.
9 Able to design a structure or pavement strengthening mechanistic methods using the annual distribution of pavement life by assigning appropriate parameters analyzed pavement structural layers operating periods.
Ratings of 3.5 and 4.5 will get students who meet the appropriate requirements of the points 1-3 and 4-6 in a very good partial, or in addition meet the requirements of a higher level.
