Road Traffic Marking Knowledge
Sep 11, 2014

1, the main function of road traffic marking is: separation of traffic, traffic level intersection intersection traffic, instructions and forecaster traffic, law enforcement and compliance basis.

1 traffic less than 15000PCU / D available long-term reticle (December) and temporary reticle (March);

2 long-term reticle according to whether the gum is divided into I (without) and II (with), according to the reflective light is divided into I greater than II, according to the anti-slip is divided into A (45), B (55).

3 temporary reticle with I can be cleared and II can not be cleared.

4 road traffic marking according to the material is divided into: solvent type (0.3-0.8), hot melt type (0.7-2.5; for the vibration of 3-7, baseline 1-2), aqueous (0.3-0.8) Points (0.4-2.5), pre-forming (0.3-2.5) five.

5 Marker colors are white, yellow (traffic flow separated), blue (non-motorized, temporary parking), orange, red.

6 marked the flash rate of 2.8-3.2 times / S, real virtual with: 2,2; 2,4; 4,4; 4,6; 6,9.

7 longitudinal marking has no effect on the driver, marking width generally take 10,15,20,25, minimum 8, maximum 30;

8 horizontal marking to be wide, generally take 20,30,40,45

9 for the normal use of the reflective line, the white reverse color factor of not less than 150 (new plan) 80 (use), yellow not less than 100 (new plan) 50 (use);

10 standard anti-skid generally not less than the original road surface, and greater than 45;

11 marking the actual position and design position of the horizontal allowable error of plus or minus 30mm

12 mark width allowable deviation of 0-5mm

13 other marking size allowable error does not exceed 5%

14 Length and spacing allowable deviation 16311 and F80 different, F80 larger.

15 Set the allowable deviation of 3 degrees

16 room temperature, heating type, hot melt type allowable deviation: - (0.03,0.05,0.10); + (0.10,0.15,0.50)

17 Hot-melt pavement marking process is: melt (above 200 degrees), cleaning and drying, pay-off, the second cleaning and drying, brushing under the paint (sub-asphalt pavement and cement pavement, Spray or roll coating), marking planning (hot melt knife coating (0.7-2.5), hot melt spray (scratch advanced 0.7-1.2), hot melt oscillation different)).

18 hot melt marking glass beads in an amount of 0.3-0.4kg / m2.

19 solvent-based construction temperature should not be less than 5 degrees. And because of thinner, less reflective. (Sub-heating and not heating two, less amount of heating in China)

20 Two-component marking line consists of A (main agent), B (curing agent) components, construction methods include: spraying, scratch coating, structural and oscillation type. Spray the marking of the dry film thickness 0.3-0.8mm, Scratch Thick 1.5-2.5mm. Two-component marking afraid of alkaline layer, the construction temperature should be between 10-35, the curing time has nothing to do with the thickness, and the ratio and the construction temperature.

21 Water Marking The construction equipment and process are the same as the solvent type, and can not be diluted with water during construction, and can not be constructed under wet environment.

 22 standard line sampling method

22.1 Longitudinal solid line or discontinuous line: Take 10 km or so as testing unit, select 100m as the inspection area at the beginning, the end and the middle of the marking line, and randomly check 10 test points randomly from each inspection area.

22.2 Graphs, Characters or Crosswalks: One test unit per 1,500 square meters, three representative figures for each test unit, character or cross-hatch for the verification area, and 5 verification points for each verification area.

22.3 The initial luminance sampling of the new marking shall be carried out in accordance with "Initial reflection brightness coefficient and test method of marking of newly laid pavement" (GB / T 21383-2008).

23 mark the thickness of the measurement

23.1 wet film: the glass or metal sheet to prevent crossed at the crossed line at the four corners of 20mm, with a wet film comb gauge hammer inserted, stable 3S made. Take the average.

23.2 Dry film: The glass or metal sheet to prevent crossed at the line, crossed, to be 5-10min, with a vernier caliper at the four corners of the amount of 20mm take average.

23.3 Formed thickness: Measured with a mark thickness gauge. Specifications 3mm and 9mm two. (As Minus)

24 swing value detection:

24.1 Pitch 125 plus or minus 1.6mm;

24.2 leveling, zero, fixed length, testing (the first value is not)

24.3 Detection of traffic flow direction. On the pattern of the standard line, take the direction of the average flow direction and 45 degrees.

25 Sprinkle glass beads distribution: 5 times the magnifying glass observation is uniform, clues, caking.

26 mark glass beads content of about 18% -25%

27 Coverage: The ratio of the brightness factor on both sides (black vs. white) when coated with no more than 5% black and no less than 80% white under the same conditions.

28 road marking paint in the provisions of the four aspects of performance: paint performance, glass bead performance, color performance, reflective road marking paint photometric performance.

29 hot melt marking the compressive strength of 12mpa; for protuberant, 23 plus or minus 1 degree 12mpa, 50 plus or minus 2 when 2mpa.

30 Glass beads should not contain lead or other heavy metals.

Glass beads have a pore size distribution of 850, 600, 300, 212, 150, 106, 90

32 glass beads round rate of not less than 80%, 600-850 to 70%

33 Glass beads Water resistance:

34 glass beads magnetic particles not more than 0.1%.

35 road marking paint composition: film (20-30), pigments (2-10), fillers (40-50), additives (2-5), dispersion medium (water, solvents, etc.).

36 film is a resin, hot melt mark generally use petroleum resin;

37 Pigments also have the effect of increasing the mechanical strength, divided into two types of inorganic pigments and organic pigments, organic pigments better color, but durability than inorganic pigments.

38 Packing: also known as physical pigments, colors and pigments can not be compared, but to improve performance and reduce costs. 39 Additives: to improve performance, including anti-settling agents, dispersants, defoamers and so on.

40 Dispersing medium: Dilute and dissolve the film-forming resin.
