Measurements of track parameters during the diagnostic process are performed in accordance with the Methodology for measuring and assessing the operational condition of roads by track depth, approved by order of the Ministry of Transport of Russia on May 17, 2002 No. OS-441-r.
Measurements are made along the right outer runway in the forward and reverse directions in areas where, with visual inspection the presence of a rut was established.
The number of measurement sites and the distance between the sites are taken depending on the length of the independent and measuring sections. A section is considered independent if, according to a visual assessment, the track parameters are approximately the same. The length of such a section can vary from 20 m to several kilometers. An independent section is divided into measuring sections with a length of 100 m each.
At each measuring section, five measurement sections are allocated at an equal distance from one another (on a hundred-meter section every 20 m), which are assigned numbers from 1 to 5. In this case, the last section of the previous measuring section becomes the first section of the next one and has the number 5/1.
The rail is laid on the protrusions of the outer track, then, with an accuracy of 1 mm, one reading is taken at the point corresponding to the largest depth of the track in each alignment, using a measuring probe installed vertically. In the absence of extrusion, the rail is laid on carriageway so that the measured track overlaps.
If there is a pavement defect in the measurement site (pothole, crack, etc.), the measurement site can be moved forward or backward up to 0.5 m to eliminate the influence of this defect on the read parameter.
The track depth measured in each alignment is recorded in the statement.

Table 10.3
For each measuring section, the estimated track depth is determined. To do this, analyze the results of measurements in five sections of the measuring section, discard the largest value, and the value of the track depth following it in the descending row is taken as the calculated value for this measuring section (hKH).
The calculated rut depth for an independent section is determined as the arithmetic mean of all values of the calculated rut depth in the measuring sections:
The assessment of the operational state of roads in terms of track depth is carried out for each independent section i by comparing the average estimated track depth h k.s. with allowable and maximum allowable values (Table 10.3).
Sections of roads with a rut depth greater than the maximum allowed values are classified as dangerous for vehicle traffic and require immediate work to eliminate the track.
Do not drive on our roads, it is sometimes scary to walk, there is a chance to stumble or slip on a rut that reaches up to ten centimeters in some places, although according to GOST it should not be at all. This is how car owners beat their expensive cars, mother our roads. Today our interview with the state inspector of road supervision Ilya Polukhin.
How many accidents are due to poor road surfaces?
- Since the beginning of the year, there have been 195 accidents, of which only one was due to defects in the road surface.
– Just one? We have terrible roads and not to say that all drivers do not comply speed mode. After all, just yesterday there was an accident in front of the "Spark", probably because of the track.
- I think that there are accidents due to the track, but the fundamental one is still traffic violation by the drivers themselves, for example, failure to provide an advantage to a car that moves along main road. Often accidents occur for a reason when the driver passes in reverse, at the same time, he is not convinced of the safety of his maneuver, and also our drivers violate the speed limit. The driver is driving, he sees that it is snowing, ice, ruts, but he does not slow down, but drives as he likes.
- What rutting is permissible according to GOST? You look - on the streets of our city, especially on Sverdlov, there are very deep ruts.
- According to GOST, there should be no rutting at all. The GOST says that the pavement of the roadway should not have subsidence, potholes, and other damage that impedes movement. Vehicle. The maximum dimensions of individual drawdowns and potholes should not exceed 15 centimeters in length, 60 centimeters in width and 5 centimeters in depth. Nothing was said about rutting.
- Did you issue instructions from the UGKh to eliminate violations?
- Last year, the traffic police of the city of Kachkanar, together with the traffic police for the Sverdlovsk region, examined the roads of the Kachkanar urban district, as a result of the survey, ruts were identified. In the name of the head of the city, an order was issued to eliminate the rutting of the road surface on Oktyabrskaya and Sverdlov streets.
- But nothing has been fixed, as there was a track, so it remained.
- Indeed, the track has not been eliminated, but temporarily installed road sign"rough road" on Oktyabrskaya street and near Mebelny.
- Who, except the mayor, received orders for bad roads?
– Instructions are received by persons responsible for the maintenance of roads in the city
How much were they fined for non-compliance?
– Fines were issued in accordance with the sanctions under articles Administrative Code RF.
– Is it convenient for you, as a driver, to drive on our roads?
- No. It seems to me that any driver will say that he feels sorry for his car.
- And what is wrong?
– Roads should be cleaned down to asphalt, but, unfortunately, this does not happen in our country.
The conclusion suggests itself, do not want to beat your cars, bought for a lot of money, walk, or drive along all Kachkanar roads at 20 km / h. Otherwise, while you wait until the officials find the money and are going to correct all the instructions, you can stay without a car.

4.7. Measuring and evaluating pavement rutting
4.7.1. Measurements of track parameters during the diagnostic process are performed in accordance with the ODM "Methodology for measuring and assessing the operational state of roads by track depth" according to a simplified version using a 2-meter rail and a measuring probe.
Measurements are made along the right outer runway in the forward and reverse directions in areas where the presence of a track is established during visual inspection.
4.7.2. The number of measurement sites and the distance between the sites are taken depending on the length of the independent and measuring sections. A section is considered independent if, according to a visual assessment, the track parameters are approximately the same. The length of such a section can vary from 20 m to several kilometers. An independent section is divided into measuring sections with a length of 100 m each.
If total length independent section is not equal to the whole number of measuring sections of 100 m each, an additional shortened measuring section is allocated. A shortened measuring section is also assigned if the length of the entire independent section is less than 100 m.
4.7.3. At each measuring section, 5 measurement sections are allocated at an equal distance from one another (on a 100-meter section every 20 m), which are assigned numbers from 1 to 5. In this case, the last section of the previous measurement section becomes the first section of the next one and has the number 5 / 1.
The shortened measuring section is also divided into 5 sections, located at an equal distance from one another.
4.7.4. The rail is laid on the protrusions of the outer track and one reading h_k is taken at the point corresponding to the largest depth of the track in each alignment, using a measuring probe installed vertically, with an accuracy of 1 mm; in the absence of bulges, the rail is laid on the carriageway in such a way as to block the measured track.
If there is a coating defect in the measurement section (pothole, crack, etc.), the measurement section can be moved forward or backward up to 0.5 m in order to eliminate the effect of this defect on the read parameter.
4.7.5. The track depth measured in each alignment is recorded in the statement, the form of which with an example of filling is given in Table 4.9.

1.2. Technical specifications and road characteristics
1.2.1. The main parameters and characteristics that determine the transport and operational condition of the road are:
Geometric parameters, which include the width of the carriageway, the edge reinforced and stopping lanes of roadsides, longitudinal slopes, radii of curves in plan and profile, slopes of bends and visibility distance;
The strength of the pavement of the carriageway, the edge reinforcement and stopping lanes of the roadsides;
Evenness and grip properties of the pavement of the carriageway, edge strengthening and stopping (reinforced with cohesive material) roadside lanes;
Strength and stability of the subgrade and its elements;
Integrity and performance of drainage and drainage structures;
Availability and required condition of elements engineering equipment and road improvements.
1.2.2. It is necessary that geometric parameters(curve radii, width of the carriageway and roadsides, dimensions of artificial structures) corresponded to the standards established for this category of road (road section). Deviations of the actual dimensions are allowed within the limits established by the relevant documents.
1.2.3. Strength pavement on roads of I - IV categories are determined by the need for unhindered access to billing period cars with axial load up to 10 tf (100 kN), and on category V roads with hard surfaces up to 6 tf (60 kN).
1.2.4. Coverings of the carriageway, edge strengthening and stopping strips of roadsides during operation must have longitudinal and transverse slopes provided for by the project, ensuring unhindered water flow.
1.2.5. It is necessary that the edges of the pavement of the carriageway, edge reinforcing and reinforced stopping lanes of roadsides be even in plan, have regular and clear outlines, and not have destruction and deformation.
1.2.6. During the operation of roads, it is necessary to ensure that the actual indicators of longitudinal evenness correspond to the maximum permissible values given in Table 1.4.

1.2.7. Rutting should not be allowed on the pavement of the carriageway, in which dangerous conditions movement and interfere with the cleaning of coatings from snow deposits and the removal of winter slipperiness. Limits of permissible and maximum allowable depth ruts are established for two methods of measuring the depth of the rut using a two-meter rail: according to a simplified method, when the rail is laid on the surface of the coating or ridges of the uplift, and according to the method of vertical marks, when the reading is taken from the rail, brought to a horizontal position (Table 1.5).

1.2.8. Rut removal works are carried out primarily on road sections with a depth greater than the maximum allowable values; On the surface of unreinforced roadsides and dividing strips that are not separated from the carriageway by curbs, it is not recommended to have ruts at the junction with carriageway and have a mark below its level by more than 3 cm with a traffic intensity above 6,000 vehicles brought to passenger car and more than 4 cm at lower intensity.
1.2.9. The roughness and condition of the road surface of the carriageway must provide the required GOST 50597-93 wheel adhesion with the coating - at least 0.3 when measured by a tire without a tread pattern and 0.4 by a tire with a tread pattern.
1.2.10. The difference in the coefficient of friction across the width of the carriageway is allowed no more than 0.1, the difference between the coefficient of adhesion of the pavement of the carriageway and the reinforced shoulder is 0.15.
1.2.11. Potholes, breaks and subsidence with dimensions in length, width and depth of more than 15 x 60 x 5 cm are not allowed on the roadway surface, and the number is more than minor damage and defects in the spring-summer-autumn periods are less than the values given in Table 1.6. The resulting deformations and destruction are eliminated within the time limits established by GOST 50597-93.
