SG bitumens, thickening at an average speed, are obtained by diluting viscous road bitumen with liquid petroleum products (LP). Depending on the class and viscosity, the following grades are established: SG 40/70, SG 70/130, SG 130/200.
To obtain liquefied bitumen, viscous road bitumen is used in accordance with GOST 22245 with a needle penetration depth of no more than 90. Fractional composition of petroleum products used as liquefiers:
To ensure the required adhesion to marble or sand, surfactants (anionic or cationic) are introduced into liquid bitumens, if necessary.
Bitumen MG
Liquid bitumen MG - slow-thickening, obtained by diluting viscous road bitumen with liquid petroleum products (MG), and obtained from residual or partially oxidized petroleum products or mixtures thereof (LGO), intended for the production of cold asphalt concrete, as well as for the construction of lightweight road surfaces and bases in II -V road climatic zones and other purposes.
Depending on the class and viscosity, the following brands of liquid bitumen are established:
MG 40/70, MG 70/130, MG 130/200;
To obtain liquefied bitumen, viscous road bitumen is used in accordance with GOST 22245 with a needle penetration depth of no more than 90.
Fractional composition of petroleum products used as thinners:
Surfactants (anionic or cationic) are added to liquid bitumen to ensure adhesion to marble or sand, if necessary.
Liquid petroleum road bitumen , having a fluid state at positive temperatures, is used as a binding material in asphalt concrete mixtures used both in cold (with a temperature of 15...20 ° C) and in warm conditions, heated to a temperature of about 100 ° C. Liquid bitumen obtained mainly by compounding viscous bitumen with a thinner. Such bitumen is often called liquefied. Sometimes liquid bitumen obtained as a residue from oil refining. Properties liquefied bitumen are largely determined by the properties of the thinners used. With time liquid bitumen thicken due to the evaporation of volatile fractions, oxidation and other processes. The most important properties of liquid bitumen: viscosity, thickening rate and properties of the residue after evaporation of volatile fractions, adhesion, flash point, weather resistance, etc. One of the most important signs of bitumen liquefaction is the rate of formation of their structure, which determines the rate of formation of coatings. Depending on the rate of evaporation of light fractions of liquefaction and the rate of thickening (structure formation) liquid bitumen are divided into two classes: 1) medium-thickening (SG) - thickening at an average speed and obtained by diluting viscous road bitumen with liquid petroleum products; 2) slow-thickening (MG) and MGO grades obtained from residual or partially oxidized petroleum products or mixtures thereof. Bitumen class is established by the amount of evaporated diluent when keeping a sample of bitumen in a thermostat at a certain temperature or a vacuum thermostat.
Depending on the class and viscosity, liquid bitumens have grades:
SG 40/70, SG 70/130, SG 130/200;
MG 40/70, MG 70/130, MG 130/200;
MGO 40/70, MGO 70/130, MGO 130/200.
Numbers in indexes grades of bitumen mean the limits of conditional viscosity using a viscometer with a 5 mm hole at 60 °C, in seconds. Bitumens of MG and SG classes until recently, they were practically not produced in our country, although GOST 11955 provides for such bitumen. Liquid bitumen must be manufactured in accordance with the requirements of the GOST 11955 standard (Table 1).
Thickening at medium speed liquid bitumen (SL) are intended for the construction of permanent and lightweight road surfaces, as well as for the construction of their foundations in all road and climatic zones of the country. Slow-thickening bitumen (MG and MGO) are intended for the production of cold asphalt concrete, as well as for the construction of lightweight road surfaces and foundations in road climatic zones II-V and for other purposes.
Liquid petroleum bitumens SG class is prepared by diluting viscous bitumen with kerosene, gasoline, naphtha, etc. Slow-thickening MG bitumens are produced by using oil products, natural tarry oils, fuel oil, etc. as a thinner. Slow-thickening bitumens can be natural - heavy resinous oils. Liquefaction viscous bitumen often changes the dispersed structure of the binder, often causing coagulation of the dispersed phase, which negatively affects its properties. Therefore, in each specific case, the thinner must be appropriately selected taking into account its fractional composition and polarity, similar to viscous bitumen.
For cooking liquid bitumen by liquefaction, viscous bitumen should have a temperature not exceeding 120 ° C (approximately 80-90 ° C when using light thinners). Used in these conditions viscous road bitumens according to GOST 22245-90 with a needle penetration depth of no more than 90.

2. For liquid bitumen grade MGO 70/130, produced from Baku oils, the flash point is allowed not lower than 140 ° WITH.
(Changed edition, Amendment No. 1, 3).
3. SAFETY REQUIREMENTS
3.1. Liquid bitumens are flammable substances with a self-ignition temperature not lower than 300° WITH.
3.2. When liquefying viscous bitumen in an open system, the temperature of the bitumen supplied for mixing with the liquefier should not exceed 120 °C.
Mixing of viscous bitumen with a diluent is carried out with inert gas or circulation.
3.3. When working with liquid bitumen, it is prohibited to use open fire and smoke in the work area.
3.4. Liquid bitumen should be heated using steam. It is allowed to use electric heating provided that the heating elements are well insulated.
When draining, filling and using liquid bitumen, the following heating temperatures are set for grades:
from 70 to 80 °C - for SG 40/70; MG 40/70;
from 80 to 90 °C - for SG 70/130; MG 70/130;
from 90 to 100 ° C - for SG 130/200; MG 130/200; MGO 40/70; MGO 70/130; MGO 130/200.
3.5. When producing, draining, loading and sampling bitumen, special clothing and personal protective equipment should be used in accordance with standard industry standards approved by the USSR State Committee for Labor and Social Affairs and the Presidium of the All-Union Central Council of Trade Unions.
3.6. When small amounts of bitumen catch fire, it is extinguished with sand, felt felt or a fire extinguisher, or special powders; Fires of spilled product that have developed over a large area are extinguished with a foam jet.
4. ACCEPTANCE RULES
4.1. Liquid bitumen is taken in batches. A batch is considered to be any quantity of bitumen that is uniform in its quality indicators and accompanied by one quality document according to GOST 1510with the obligatory indication of the trademark.
The quality document also indicates the mineral material (sand or marble) with which the adhesion test was carried out.
(Changed edition, Amendment No. 1).
4.2. Sample size - by GOST 2517.
4.3. If unsatisfactory test results are obtained for at least one of the indicators, repeat testing of a sample from a double sample is carried out.
The results of repeated tests apply to the entire batch.
5. TEST METHODS
5.1. Samples of liquid bitumen are taken according to GOST 2517. The mass of the combined sample of each brand of liquid bitumen is 1.0 kg.
5.2. The adhesion test with marble or sand is carried out according to GOST 11508for liquid bitumen grades MGO using method A, for grades SG and MG - using method B.
Liquid bitumens, to which cationic substances have been added, are tested for adhesion to sand;
liquid bitumen with anionic substances - with marble.
5.3. Conditional viscosity is determined according to GOST 11503-74 with the following addition: the sample is pre-cooled to room temperature, kept for at least 1 hour, then heated for 2-3° C above test temperature.
(Introduced additionally, Amendment No. 3).
6. PACKAGING, LABELING, TRANSPORTATION AND STORAGE
6.1. Packaging, labeling, transportation and storage of liquid bitumen - according to GOST 1510.
According to the degree of transport danger, liquid bitumen is classified as hazard class 9, subclass 9.1, category 9.12 according to GOST 19433.
Liquid bitumen of classes SG and MG should be stored in tanks equipped with safety valves.
(Changed edition, Amendment No. 1, 2).
7. MANUFACTURER WARRANTY
7.1. The manufacturer guarantees that the quality of liquid bitumen meets the requirements of this standard subject to the conditions of transportation and storage.
7.2. The guaranteed shelf life of liquid bitumen from the date of manufacture should be for the SG class - 6 months; MG class - 8 months; MGO class - 1 year.
