Asphalt of a project concrete construction plan
(1) Mixing station 1. Raw materials: various materials have been mobilized and passed the inspection. 2. Mix proportion: according to the design requirements, our department has designed the production mix proportion of (SBS) modified asphalt concrete. As for the supply of cold materials, the materials shall be loaded in strict accordance with the proportion set by the target mix proportion, that is, 5~10mm crushed stone, 0~5mm stone chips, river sand: mineral powder=44:33:17:6. Through Marshall test, the optimal asphalt consumption is determined to be 5.62%, that is, the optimal asphalt stone ratio is 5.95% 3. Mechanical equipment: (1) loading equipment: one ZL50D loader (2) transportation equipment: nine dump trucks 4 Personnel organization: (1) Technical personnel: (2) Mechanical operators: 9; (3) Testing personnel: (4) Auxiliary workers: 20; 5. Main experimental instruments: extractor, thermostatic water bath, Marshall tester, ductility meter, softening point meter, asphalt concrete sieve, electronic balance, penetrometer, drying oven, pendulum tester and other mixing material inspection instruments: 1 set.
