<\/a>laying asphalt with bitumen<\/figcaption><\/figure>\n Asphalt mix <\/strong> generally consists of two main components – rock aggregates <\/strong> and bituminous binder <\/strong>. Rock materials<\/strong> provide the required load-bearing capacity of the asphalt pavement <\/strong>, and bitumen <\/strong> provides a strong interconnection <\/strong> between the stones, as well as hydrophobicity <\/strong> The amount of bitumen in asphalt mixtures varies depending on their purpose, but its presence is mandatory in all cases. <\/p>\n Bitumen <\/strong> is an organic material obtained as a final product from the processing of oil <\/strong>, but which can also be found in natural deposits <\/strong>. It is black in color <\/strong> and has a specific pungent odor. Bitumen <\/strong> has excellent waterproofing <\/strong> properties due to its hydrophobic <\/strong> nature, expressed in the ability of bitumen <\/strong> to repel water droplets. It is widely used in road construction <\/strong>, as well as in construction of buildings and facilities <\/strong> for waterproofing <\/strong> of foundations <\/strong>, retaining walls <\/strong>, superstructure of bridge structures <\/strong>, waterproofing of roofs <\/strong> and sheds, etc. <\/p>\nIn order to be used in construction products <\/strong>, bitumen <\/strong> must meet all the requirements of the tests according to the standards <\/strong> of the Bulgarian Institute for Standardization and the European norms. Some of the characteristics for which bitumen <\/strong> is tested are softening point <\/strong>, bitumen penetration <\/strong>, Fraas breakage <\/strong>, viscosity <\/strong> and others. <\/p>\nBituminous primer <\/h3>\n
Bitumen <\/strong> is one of the main ingredients in the asphalt mix <\/strong>, but it also serves as a glue <\/strong> between the individual asphalt layers <\/strong> or during repairs. When performing a road construction <\/strong> of asphalt concrete <\/strong>, each individual layer must be covered with bitumen emulsion <\/strong> ( bitumen primer <\/strong>) before laying. on the next. This helps the layers <\/strong> to stick together and work together to take the load off the vehicles. In addition, bitumen primer <\/strong> covers dust particles that would compromise the quality of the asphalt pavement <\/strong>. <\/p>\n Waterproofing <\/strong> is an integral part of any modern construction <\/strong> – be it a building or a facility. Bitumen primer <\/strong> is the perfect tool for this purpose, as it is hydrophobic <\/strong> and does not allow water to pass through the surfaces treated with it. Bitumen primer <\/strong> is used for waterproofing <\/strong> of foundations <\/strong> in buildings <\/strong> and bridges <\/strong>, in waterproofing of retaining walls <\/strong>, for roof waterproofing <\/strong>. In combination with bitumen tiles <\/strong>, bitumen primer <\/strong> creates a dense barrier for water droplets and prevents them from entering the living space under the roofs <\/strong>. <\/p>\nBase preparation and asphalting <\/h3>\n
Preparing the substrate before asphalting <\/strong> is one of the most important steps before laying asphalt layers <\/strong>. A few simple steps ensure proper execution of the road structure <\/strong>: <\/p>\n\n- Cleaning – the removal of all dust, humus particles, small fractions and contaminants of arable nature provide a good contact surface between the old and the new asphalt layer <\/strong>. It can be done with brushes or brooms, and at best – with an air jet <\/strong>. <\/li>\n
- Drying – it is necessary to remove any moisture from the surface of the previous asphalt layer <\/strong> or the hole that will be asphalted <\/strong>, as the hydrophobicity <\/strong> of bitumen <\/strong> will prevent proper adhesion of the old asphalt layer <\/strong> and the new asphalt mixture <\/strong>. <\/li>\n
- Priming <\/strong> – the application of bitumen emulsion <\/strong> ( bitumen primer <\/strong>) is extremely important as it ensures good adhesion of the old and new asphalt mixture <\/strong>. Priming <\/strong> should be done in several layers (minimum 2) for optimal effect <\/strong>. <\/li>\n
- Asphalting <\/strong> – After applying bituminous primer <\/strong>, the asphalting <\/strong> itself can be performed. It is necessary to comply with all technological prescriptions of civil engineers <\/strong> – compliance with asphalt technology <\/strong>, ensuring the required temperature of asphalt <\/strong>, compliance with meteorological requirements etc. <\/li>\n<\/ul>\n
