6 Acceptance rules

6.1 Acceptance of mixtures is carried out in batches. 6.2 When accepting and unloading hot mixtures, a batch considers the amount of a mixture of the same composition produced at one installation during a shift, but not more than 600 tons. more than 200 tons. If, after acceptance, the mixture is placed in a warehouse, then mixing it with another cold mixture of the same composition is allowed. When shipping a cold mixture from a warehouse to cars, a batch is the amount of a mixture of one composition shipped to one consumer during the day. When a cold mixture is shipped from a warehouse to railway or water vehicles, a batch is considered to be the amount of a mixture of one composition shipped to one railway train or to one barge. 6.4 The amount of the supplied mixture is determined by weight. When shipped to wagons or cars, the mixture is weighed on railway or truck scales. The mass of the cold mixture shipped to ships is determined by the ship's draft. 6.5 To check the compliance of the quality of mixtures with the requirements of this standard, acceptance and periodic tests are carried out. 6.6 During acceptance testing of mixtures, one combined batch sample is taken according to GOST 12801 and the following is determined: the temperature of the mixture being shipped when it is discharged from the mixer or storage bin; grain composition of the mineral part of the mixture; water saturation - for all mixtures; compressive strength at 50 ° C, 20 ° C and water resistance - for hot mixes; compressive strength at a temperature of 20 ° C, including in a water-saturated state, and caking (2 - 3 times per shift) - for cold mixtures. The above indicators for cold mixtures are determined before warming up. 6.7 During periodic quality control of mixtures, the porosity of the mineral part is determined; residual porosity; water resistance with prolonged water saturation; limit, compressive strength: at a temperature of 20 ° C after warming up and after prolonged water saturation for cold mixtures; at a temperature of 0 ° C - for hot mixtures; adhesion of bitumen with the mineral part of the mixtures; shear resistance and crack resistance, subject to the availability of these indicators in the design documentation; homogeneity of mixtures. The specific effective activity of natural radionuclides in mixtures and asphalt concrete is taken according to the maximum value of the specific effective activity of natural radionuclides contained in the mineral materials used. This data is also indicated by the document on the quality of the supplier enterprise. In the absence of data on the content of natural radionuclides, the manufacturer, using a specialized laboratory, performs input control of materials in accordance with GOST 30108. 6.8 Periodic control is carried out at least once a month, as well as with each change in materials used in the preparation of mixtures; the homogeneity of the mixtures, estimated by the coefficient of variation according to 5.14, is calculated monthly. Shear resistance and crack resistance, subject to the availability of these indicators in the design documentation and the supply contract, are determined at least once a month if the manufacturer has the equipment or once every two months when testing in specialized laboratories equipped with necessary equipment.(Changed edition. Rev. No. 2). 6.9 For each batch of the shipped mixture, the consumer is issued a quality document, which indicates the results of acceptance and periodic tests, including: - manufacturer's name; - number and date of issue of the document; - name and address of the consumer; - type, type and brand of the mixture; - mass of the mixture; - shelf life of the cold mixture; - water resistance for hot mixes; - caking for cold mixtures; - water saturation; - water resistance at long water saturation for hot mixes; - ultimate compressive strength: at 20 ° C before heating and after heating for cold mixes; at 50°C and 0°C for hot mixes; - residual porosity and porosity of the mineral part of the mixture; - shear resistance and crack resistance, subject to the presence of these indicators in the design documentation and the supply contract; - specific effective activity of natural radionuclides; - designation of this standard. When the mixture is shipped to the consumer, each car is accompanied by transport documentation, which indicates: - name of the manufacturer; - address and name of the consumer; - date of manufacture; - release time from the mixer; - temperature of the shipped mixture; - type and quantity of mixture. (Changed edition. Rev. No. 2). 6.10 The consumer has the right to conduct a control check of the compliance of asphalt concrete mixtures with the requirements of this standard, observing the standard methods for sampling, sample preparation and testing specified in GOST 12801, while applying the following sampling procedure. 6.11 For control tests of asphalt concrete mixtures shipped to cars, 9 combined samples are taken from each batch directly from car bodies. For control tests of cold asphalt mixes shipped to railway or water vehicles, 9 samples are taken from each wagon or barge. Each sample of the mixture is taken from different places of the wagon or barge. The samples taken are not mixed and three samples are tested first. If satisfactory test results are obtained, the remaining samples are not tested. If unsatisfactory test results are obtained for at least one sample out of three, the remaining six samples are tested. In case of unsatisfactory test results of at least one sample out of six, the batch is rejected.

6. Acceptance rules

6.1 Acceptance of mixtures is carried out in batches.

6.2 When accepting and shipping hot mixtures, a batch is considered to be the amount of a mixture of the same composition produced at one installation during a shift, but not more than 600 tons.

6.3 When accepting cold mixes, a batch considers the amount of a mix of the same composition produced by the plant during one shift, but not more than 200 tons.

If, after acceptance, the mixture is placed in a warehouse, then mixing it with another cold mixture of the same composition is allowed.

When shipping a cold mixture from a warehouse to cars, a batch is the amount of a mixture of one composition shipped to one consumer during the day.

When a cold mixture is shipped from a warehouse to railway or water vehicles, a batch is considered to be the amount of a mixture of one composition shipped to one railway train or to one barge.

6.4 The amount of the supplied mixture is determined by weight.

When shipped to wagons or cars, the mixture is weighed on railway or truck scales. The mass of the cold mixture shipped to ships is determined by the ship's draft.

6.5 To check the compliance of the quality of mixtures with the requirements of this standard, acceptance and periodic tests are carried out.

6.6 During acceptance testing of mixtures, one combined sample is taken from the batch according to GOST 12801 and the following is determined: the temperature of the mixture being shipped when it is discharged from the mixer or storage bin; grain composition of the mineral part of the mixture; water saturation - for all mixtures; compressive strength at 50°C, 20°C and water resistance - for hot mixes; ultimate compressive strength at a temperature of 20°C, including in a water-saturated state, and caking (2-3 times per shift) - for cold mixes. The above indicators for cold mixtures are determined before warming up.

6.7 During periodic quality control of mixtures, the porosity of the mineral part is determined; residual porosity; water resistance with prolonged water saturation; compressive strength: at a temperature of 20°C after warming up and after prolonged water saturation for cold mixes; at a temperature of 0°C - for hot mixes; adhesion of bitumen with the mineral part of the mixtures; shear resistance and crack resistance, subject to the availability of these indicators in the design documentation; homogeneity of mixtures.

The specific effective activity of natural radionuclides in mixtures and asphalt concrete is taken according to the maximum value of the specific effective activity of natural radionuclides contained in the mineral materials used. This data is indicated in the quality document by the supplier enterprise.

In the absence of data on the content of natural radionuclides, the manufacturer, using a specialized laboratory, carries out incoming control of materials in accordance with GOST 30108.

6.8 Periodic control is carried out at least once a month, as well as with each change in the materials used in the preparation of mixtures; the homogeneity of mixtures, estimated by a coefficient of variation of 5.14, is calculated monthly.

Shear resistance and crack resistance, subject to the availability of these indicators in the design documentation and the supply contract, are determined at least once a month if the manufacturer has the equipment or once every two months when testing in specialized laboratories equipped with the necessary equipment.

6.9 For each batch of the shipped mixture, the consumer is issued a quality document, which indicates the results of acceptance and periodic tests, including:

Manufacturer's name;

Number and date of issue of the document;

Name and address of the consumer;

Type, type and brand of the mixture;

6 Acceptance rules

6.1 Acceptance of mixtures is carried out in batches.

6.2 When accepting and shipping hot mixtures, a batch is considered to be the amount of a mixture of the same composition produced at one installation during a shift, but not more than 600 tons.

6.3 When accepting cold mixes, a batch considers the amount of a mix of the same composition produced by the plant during one shift, but not more than 200 tons.

If, after acceptance, the mixture is placed in a warehouse, then mixing it with another cold mixture of the same composition is allowed.

When shipping a cold mixture from a warehouse to cars, a batch is the amount of a mixture of one composition shipped to one consumer during the day.

When a cold mixture is shipped from a warehouse to railway or water vehicles, a batch is considered to be the amount of a mixture of one composition shipped to one railway train or to one barge.

6.4 The amount of the supplied mixture is determined by weight.

The mixture when shipped to wagons or cars is weighed on

railway or truck scales. The mass of the cold mixture shipped to ships is determined by the ship's draft.

6.5 To check the compliance of the quality of mixtures with the requirements of this standard, acceptance and periodic tests are carried out.

6.6 During acceptance testing of mixtures, one combined sample is taken from the batch according to GOST 12801 and the following is determined: the temperature of the mixture being shipped when it is discharged from the mixer or storage bin; grain composition of the mineral part of the mixture; water saturation - for all mixtures; compressive strength at 50 °C, 20 °C and water resistance - for hot mixes; compressive strength at a temperature of 20 ° C, including in a water-saturated state, and caking (2-3 times per shift) - for cold mixes. The above indicators for cold mixtures are determined before warming up.

6.7 During periodic quality control of mixtures, the porosity of the mineral part is determined; residual porosity; water resistance with prolonged water saturation; compressive strength: at a temperature of 20 °C after heating and after prolonged water saturation for cold mixtures; at a temperature of 0 °C - for hot mixes; adhesion of bitumen with the mineral part of the mixtures; shear resistance and crack resistance, subject to the availability of these indicators in the design documentation; homogeneity of mixtures.

The specific effective activity of natural radionuclides in mixtures and asphalt concrete is taken according to the maximum value of the specific effective activity of natural radionuclides contained in the mineral materials used. This data is indicated in the quality document by the supplier enterprise.

In the absence of data on the content of natural radionuclides, the manufacturer, using a specialized laboratory, carries out incoming control of materials in accordance with GOST 30108.

6.9 For each batch of the shipped mixture, the consumer is issued a quality document, which indicates the results of acceptance and periodic tests, including:

Manufacturer's name;

Number and date of issue of the document;

Name and address of the consumer;

Type, type and brand of the mixture;

The mass of the mixture;

Shelf life of cold mix;

Water resistance for hot mixes;
