METHOD FOR PRODUCING HOT crushed stone asphaltic mix with crushed limestone dropout MARKS 200 ... 400

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to road building, namely to technologies of road concrete mixtures for arrangement of upper and lower layers of automobile roads coatings. Method of obtaining hot macadam road concrete mixture with sweepings of limestone G 400 crushing includes preparation of hot road concrete mixture for upper and lower layers of coatings, which consists of, wt %: macadam of strong rocks - 46…48, sweepings of strong rock crushing (crushed sand) - 38…50, limestone G 400 crushing sweepings - 3…15 and bitumen-4.7…4.9 (over 100%). Liquid aniline-containing wastes of chemical factory are preliminarily introduced into viscous bitumen in quantity 0.6…1.00% of bitumen weight.;EFFECT: binding agent with correspondence of other parameters to requirements of GOST9128-2009 to hot road concretes of B type.;4 tbl
