Abstract
Изобретение относитс к дорожностроительным материалам и может быть использовано при приготовлении асфальтобетонных смесей дл дорожного и аэродромного строительства. Целью изобретени вл етс повьппение прочности при сжатии асфальтобетона при 20 С. Дл приготовлени асфальтобетонной смеси гудрон нагреваю до 200-300 С и вспенивают отходом производства фосфорной кислоты - фосфогип- сом в количестве 5-12% от массы гуд- рона. Полученное вспененное в жущее смешивают с минеральным заполнителем. Прочность при сжатии асфальтобетона при 20 С 2,7-3,6 МПа. 2 табл. 8 (ЛThe invention relates to road building materials and can be used in the preparation of asphalt mixes for road and airfield construction. The aim of the invention is to increase the compressive strength of asphalt concrete at 20 ° C. To prepare an asphalt concrete mixture, the tar is heated to 200-300 ° C and foamed with phosphoric acid production waste - phosphogypsum in an amount of 5-12% by weight of tar. The resulting foamed substance is mixed with mineral aggregate. Compressive strength of asphalt concrete at 20 C 2.7-3.6 MPa. 2 tab. 8 (L

Изобретение относитс к дорожно- 26-29; 85,05- 2-4; ,. 2-10; F 0,2 - строительйым материалам и может быть 0,6; вода - остальное, использовано при приготовлении асфальтобетонных смесей дл дорожного и аэродромного строительства.The invention relates to road 26-29; 85.05-2-4; , 2-10; F 0,2 - building materials and may be 0,6; water - the rest, used in the preparation of asphalt mixes for road and airfield construction.
Целью изобретени вл етс повышение прочности при сжатии асфальтобетона при 20°С.The aim of the invention is to increase the compressive strength of asphalt concrete at 20 ° C.
Способ осуществл етс следующим образом.The method is carried out as follows.
Гудрон нагревают до 200-300°С,при которой он склонен к интенсивному окислению. Вввод т влажный фосфогипс, который вызывает его вспенивание, д органического в жущего и вспенивани Вспененный таким образом гудрон сме- его с последующим смешением с.минеральным заполнителем , о тлич.аю- щ и и с тем, что, с целью повьппе- ни прочности при сжатии асфальтобе- 2Q тона при 20°С, черное органическое в жущее - гудрон нагревают до 200 - 300 С, а вспенивают путем введени отхода производства фосфорной кислоты - фосфогипса в количестве 5 25 12% от массы гудрона.Tar is heated to 200-300 ° C, at which it is prone to intense oxidation. Wet phosphogypsum, which causes its foaming, is introduced. Organic sticking and foaming. The foam thus molded is mixed with the subsequent mixing of the mineral mineral aggregate, which is different with that and in order to increase its strength. when squeezing asphalt-2Q tones at 20 ° C, the black organic sticking agent - tar is heated to 200 - 300 ° C, and foamed by the introduction of waste phosphoric acid production - phosphogypsum in an amount of 5-25 12% by weight of tar.
