Mechanisms Sand Has Many Advantages

Highway pavement is asphalt pavement, and in the construction managementof asphalt pavement, as long as the raw materials and the number is adequate,road construction have the chance more than 70% to build well, therefore,asphalt pavement with good quality needs a guarantee of stable quality coarseand fine aggregate. Natural sand has light round particle, which is good forenhancing the workability of the asphalt concrete, but its poor adhesion withasphalt will reduce water stability of asphalt concrete magnetic separators from slag. The mechanisms sand isable to overcome the defects of natural sand.
Compared with natural sand,mechanisms sand has the following advantages: regular in shape; less flakinessparticles; less dust content, and the mechanisms sand can increase the frictionbetween the particles; has obviously high temperature resistance to rutting; canenhance the adsorption capacity of the stone and asphalt; increase thickness ofasphalt film; provide good stability to the pavement. Under externaldisturbances in high temperature, the internal mineral aggregate particlearrangement changes, at the same time, a wealth of edges and corners strengthenthe role of pellets embedded squeeze; the friction resistance of mechanisms sandenhances the asphalt mixture resistance in high temperature, deformationcapacity, water stability and slip resistance; surface roughness, angularity;Therefore, sand makingmachineor sand makerisbeneficial to the construction of the highway for speeding up its pace andensuring its quality.
For asphalt pavement construction, highway asphaltpavement with smaller traffic can be prepared with S-15 fine aggregate. Inaddition, the right mineral aggregate of 0.075-0.15mm and 0.15-0.3mm must beretained in production of sand mechanism, and mechanisms sand must be producedby dry type.
