Abstract

The invention relates to the field of application of mountain flour, provides application of mountain flour in asphalt concrete, aims to recycle and reuse mountain flour piled in a stone factory in asphalt concrete and recycle and reuse aged asphalt, and aims to solve the problems that in the prior art the environment can be polluted and the resources are wasted as mountain flour and aged asphalt are piled. The application comprises the following treatment steps: (1) selecting a stone material; (2) drying; (3) grinding; (4) preparing asphalt; and (5) applying the mountain flour prepared in the step (3) and coal cinder to the asphalt concrete, wherein the mass ratio of the mountain flour to the coal cinder and the asphalt concrete is 1:(0.3-0.5):(50-75).

Description

technical field [0001] The invention relates to the application field of stone powder, in particular to an application of stone powder in asphalt concrete. Background technique [0002] Asphalt concrete can be divided into petroleum asphalt and coal asphalt according to the different binders used. The asphalt pavement paved with two kinds of asphalt concrete has the advantages of good mechanical strength, wear resistance, comfortable driving, small vibration, low noise, and simple construction. With the large-scale rollout of highway engineering construction, the proportion of asphalt pavement in high-grade roads is increasing. Traditional asphalt concrete pavement often has cracks. Pollution has become an important social problem and needs to be dealt with vigorously. In addition, in the prior art, a large amount of waste rock powder will be produced during stone processing, and the discharge or accumulation of these waste rock powder will cause environmental pollution, e...
