Assessment criteria

Lecture
Lecture is to solve 10 questions in the test. Each question is scored by the teacher on a scale of 0-1. A necessary condition to obtain credit lectures minimal number of points - 6 Final assessment: 3,0 - 6 points., 3.5 - 7 points., 4.0 - 8 points, 4.5 - 9 points.), 5.0 10 points.
Assessment must pass without the use of materials and assistance, and without communicating with other people. Assessment takes about 30 minutes.

Exercise Design:
The assessment of adequate (3.0), the student:
One calculates correctly traffic category in the reference period.
2 Place the properly designed pavement design method is able to determine the sheet and strengthen the deflection method.
3 He knows the rules for proper selection of the composition of the asphalt mix.
The assessment of good (4.0), the student:
4 Meets the requirements of paragraphs 1-3.
5 Can the construction of pavement design methods directory under difficult conditions of soil and water. Knows basic technical layers of road pavement construction.
6 It can strengthen the road surface design using middleware.
7 Place the properly adjust the grading curve of asphalt mixes.
For a very good student (5.0):
Meets 8 points 1-7.
9 Can the construction of pavement design methods directory under difficult conditions, and soil and water properly applied additional layers of filtration and valve.
10 It can strengthen the road surface design using middleware package including a minimum of asphalt layers.

Ratings of 3.5 and 4.5 will get students who meet the appropriate requirements of the points 1-3 and 4-7 in a very good partial, or in addition meet the requirements of a higher level.

Laboratory:
The assessment of adequate (3.0), the student:
He can do one weighed sample of mineral mixture based on the composition of the mineral aggregate asphalt mixes.
2 It can take a minimum asphalt content in asphalt mixtures.
3 Place perform basic laboratory designation for asphalt, aggregates and asphalt mixes.
The assessment of good (4.0), the student:
4 Meets the requirements of paragraphs 1-3.
5 Can the grounds designed to provide the optimal composition of asphalt mixes.
6 Place interpreted (in a good degree) obtained for laboratory testing of asphalt, aggregates and asphalt mixes
For a very good student (5.0):
Meets 7 points 1-6.
8 Place correctly interpret the results of studies carried out for the asphalt mix and knows the incorporation of technology in the construction of MMA road surface. It is estimated, which should correspond to the parameters bituminous mixtures embedded in pavement construction for the results of laboratory tests (designed asphalt mix).

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.

In the event of limitation or suspension of the functioning of universities, credits will be awarded with the use of distance learning methods and techniques. The rules for obtaining credits remain unchanged.
Oral credits may be used for less than 10 people.
