Non-compliance with the standard is punishable by law

This standard applies to asphalt mixtures used for coating and founding roads, airfields, city streets and squares, roads of industrial enterprises, as well as asphalt (compacted asphalt mix). Asphalt concrete mixture is prepared by mixing in mixing plants in the heated state of crushed stone (gravel), natural or crushed sand, mineral powder and petroleum road bitumen, taken in the ratios determined by the requirements of this standard. The area of \u200b\u200bapplication of asphalt mixes is given in the recommended applications 2-4.

1. CLASSIFICATION

1.1. Asphalt concrete mixtures (hereinafter - mixtures) are divided into crushed stone, gravel and sand. 1.2. Mixtures, depending on the viscosity of the bitumen and application conditions, are divided into the following types: hot - prepared using viscous bitumen and applied immediately after preparation with a temperature of at least 120 ° C; warm - prepared using both viscous and liquid bitumen and applied immediately after preparation with a temperature not lower than 70 ° С; cold - prepared using liquid bitumen, allowed for long-term storage and used with a temperature not lower than 5 ° C. 1.3. Hot and warm mixtures, depending on the largest grain size of mineral materials, are divided into: coarse-grained f - with grains up to 40 mm in size; fine-grained "" "" 20 mm; sandy »» »» 5 mm. Cold mixtures are subdivided into fine-grained and sandy. 1.4. Asphalt concrete from hot and warm mixtures, depending on the value of the residual porosity, is divided into: dense with residual porosity from 2 to 7% inclusive .; porosity e with residual porosity s. 7 to 12% incl .: highly porous with residual porosity of st. 12 to 18% incl. 1.5. Crushed stone and gravel mixtures, depending on the content of crushed stone or gravel, and sand mixtures, depending on the type of sand, are divided into types indicated in Table. 1.

Hot and warm mixtures of type A, depending on their quality indicators, are divided into two grades: I and II, types B, C and D - into tr and mark and: I, II and III, type D - into two grades: II and III. Cold mixes and types B x and B x are subdivided into two mark and: I II, type G x can be only I marks, type D x - only II mark and.

The cost of implementing these structures is comparable, which may be important when choosing the type of pavement, for example, in the case of bicycle paths. Whether it is colored cobblestone, or a more comfortable, bitumen pavement with a color-sensitive, heat-resistant surface, this question will be answered by anyone who rides a bicycle. The condition for the correct painting of a thin layer of hot wear should correspond to the requirements for the materials: binder, aggregate, and the type of mixture of mineral-asphalt coating used. The new one can be made of a thin layer about 2 cm thick from the sidewalk in hot technology, which is not yet used by most Polish road companies.

Applications in Poland and much more. The technology of colorful asphalt pavement is found in Poland with growing interest. Until now, this technology has been applied in the following places.

It is absolutely necessary to restore a destructible excavation drainage or frost-resistant layer. The thickness of the reproduced layer should be the same as the existing layer. The basic material, especially in the lower layer, can be used if it is stored separately and is not contaminated with soil and other foreign materials. It is imperative to observe the restoration of layers of such thickness and materials such as existing road surface construction.

Full restoration of the pavement surfaces should be carried out at the curb along the edge of the road, if the distance between the curbs, resistors and the perimeter of the sidewalk edge is less than 1, 50 m, unless the road manager has indicated otherwise. paving and bitumen layers. The reconstruction of the bitumen coating should take place in the case of a continuous longitudinal excavation located in the middle of the carriageway. Do not place the cutting edges of the bitumen coating in the axis. This is due to the fact that it is impossible to draw lanes of segregation on flooded liquid bitumen, combining new and existing sidewalks. Cutting or milling of the edges and beams of existing sidewalks is indicated at the beginning of the excavation. On a prepared base, that is, cleaning and spraying with an asphalt or asphalt emulsion, a leveling or bonding layer should be decomposed, and then a layer of mineral asphalt. The composition of the asphalt mix and the thickness of the layers must comply with the design documentation and the requirements and conditions of the applicable standards and specifications. Recall that the thickness of the moving layers cannot be less than the thickness of the existing layers. A layer should be applied between the layers of bitumen asphalt by spraying the substrate with a layer of liquid asphalt or asphalt emulsion with properties adapted to existing conditions. The substrate should be sprayed in sufficient quantity to bind the layers without an excess binder evenly over the entire surface in accordance with standard instructions. The surface layers must be tightly sealed using a set of rollers or mechanical seals. The surface must be aligned with the existing surface, while maintaining the required gradients. Welding on the surface of the sidewalk should be poured with asphalt. Work should be carried out in favorable weather conditions.

Periodic monitoring should be carried out less than once every six months and with each change in the materials used in the preparation of mixtures, as well as in the design of mixtures. 5.8. The consumer has the right to carry out a control check of the compliance of asphalt concrete mixtures with the requirements of this standard, while observing the sampling procedure established by this standard and GOST 12801-84, and using the test methods specified in GOST 12801-84. 5.9. For control tests of asphalt concrete mixtures shipped to automobiles, three samples are taken from each batch directly from the car bodies. For control tests of cold asphalt mixtures. shipped to rail or water vehicles, three samples are taken from each wagon or barge. Each sample of the mixture is taken from different places of the car or barges and at different depths. Samples are not mixed and tested separately. Upon receipt of unsatisfactory test results of at least one sample, repeated tests of the military quantity of the sample are performed. In case of unsatisfactory results of repeated tests, the batch is rejected. 5.10.
