Title:
STEPWISE ASPHALT MIXTURE AGITATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/248922
Kind Code:
A1
Abstract:
A stepwise asphalt mixture agitation method, comprising a first hot compartment group (1), a second hot compartment group (2), a first aggregate scale (3), a second aggregate scale (4), an asphalt scale (5), and a agitation tank (6), the first hot compartment group (1) being connected to the agitation tank (6) by means of the first aggregate scale (3), the second hot compartment group (2) being connected to the agitation tank (6) by means of the second aggregate scale (4), and the asphalt scale (5) being connected to the agitation tank (6). The second aggregate scale (4) receives and measures coarse aggregate in the second hot compartment group (2), and the measured coarse aggregate and a preset proportion of asphalt in the asphalt scale (5) are sequentially delivered into the agitation tank (6) to perform primary agitation; and the first aggregate scale (3) receives and measures fine aggregate in the first hot compartment group (1), and the measured fine aggregate and the remaining asphalt in the asphalt scale (5) are sequentially delivered into the agitation tank (6) to perform secondary agitation. The present method ensures that the surfaces of all coarse aggregate is covered by asphalt, thus avoiding the uneven thickness of the asphalt film formed by the asphalt mixture covering the surface of the aggregate and powder.
