Embodiment Construction
[0017] Such as figure 1 As shown, a construction process of ATB asphalt macadam base includes the following processes:
[0018] 1. Selection of raw materials:
[0019] The quality requirements and technical indicators of asphalt, permeable coal tar pitch, viscous layer emulsified asphalt, coarse and fine aggregates, fillers, etc. shall be determined according to the structural type of the asphalt concrete surface layer design and its corresponding technical specification requirements and construction methods. The quality of asphalt mixture The indicators mainly refer to "Technical Specifications for Construction of Highway Asphalt Pavement" (JTG F40-2004), the owner's design documents or related technical specifications.
[0020] 1) coarse aggregate
[0021] The limestone gravel produced by the impact crusher is clean, free of miscellaneous rocks, large in size, rough in surface, square in shape and good in adhesion, with less flat and needle-like particles.
[0022] Strict...
