Abstract
Изобретение относитс к способам приготовлени дорожно-строительных материалов и может быть использовано при устройстве покрытий и оснований промышленных и сельскохоз йственных дорог. Цель изобретени - снижение энергозатрат. Способ приготовлени асфальтобетонной смеси заключаетс в нейтрализации нерастворимого в воде кислого гудрона отходом содового производства в соотношении 1:(0,43-2,3) при 80-120°С и измельчении его до порошкообразного состо ни с последующим смешением в количестве 11,0-15,8 мас.% с 5,2-5,9 мас.% нефт ного битума и наполнителем. Прочность при сжатии при 20°С получаемого асфальтобетона 8,5-10,2 МПа, коэффициент водостойкости 0,75-0,91. 1 табл.The invention relates to methods for preparing road-building materials and can be used in arranging coatings and bases for industrial and agricultural roads. The purpose of the invention is to reduce energy consumption. The method of preparation of the asphalt concrete mixture consists in neutralizing acidic water-insoluble acid tar with soda ash production in a ratio of 1: (0.43-2.3) at 80-120 ° C and grinding it to a powder, followed by mixing in an amount of 11.0- 15.8 wt.% With 5.2–5.9 wt.% Of petroleum bitumen and filler. Compressive strength at 20 ° С of asphalt concrete obtained is 8.5-10.2 MPa, water resistance coefficient is 0.75-0.91. 1 tab.
Description
Изобретение относитс к способам приготовлени дорожьо-строительных материалов и может быть использовано :при устройстве покрытий и оснований промьшшенных и сельскохоз йственных дорог.. The invention relates to methods for preparing road-building materials and can be used: in arranging coatings and bases of industrial and agricultural roads.
Цель изобретени - снижение энергозатрат .The purpose of the invention is to reduce energy consumption.
Изобретение осуществл етс следующим образом.The invention is as follows.
Нерастворимьй в воде кисльй гудрон перемешивают с отходом содового производства при. 80-120 с. Получен- ньй порошкообразный материал сущат до хрупкого состо ни и измельчают до размера частиц менее 0,14 мм.Water-insoluble acidic tar is mixed with waste soda production at. 80-120 s. The resulting powdered material is brittle and crushed to a particle size of less than 0.14 mm.
Полученный порошкообразный нейтрализованный кислый гудрон перемешивают с напонителем, нагретым до 170 , в течение 60 с. Затем ввод т нагретый до 160 с нефт ной битум.The obtained powdered neutralized acid tar is mixed with a filler heated to 170 for 60 s. Heated bitumen heated to 160 s is then introduced.
Используемый в качестве нейтрализующего агента отход содового производства по содержанию кальциевьк соединений близок к известн ковому минеральному порошку.The waste of soda production used as a neutralizing agent in terms of the content of calcium compounds is close to limestone mineral powder.
Примеры конкретного выполнени способа и свойства получаемого асфальтобетона приведены в таблице.Examples of the specific implementation of the method and the properties of the resulting asphalt are given in the table.
Как видно из приведенных данных, предлагаемый способ позвол ет снизить энергозатраты на получение асфальтобетона , причем свойства получаемого асфальтобетона наход тс на уровне прототипа.As can be seen from the above data, the proposed method allows to reduce the energy consumption for the production of asphalt concrete, and the properties of the asphalt concrete obtained are at the level of the prototype.
