The invention discloses a
cement stabilized macadam base and a construction method thereof, and belongs to the technical field of highway pavement pavements. The
cement stabilized macadam base comprises aggregate,
cement, water, a
polymer mixture, magnetized
polyvinyl alcohol fibers and serpentine
asbestos powder; and the base is prepared by mixing and constructing the following components, by
mass, 4.5% of the cement, 4.5% of the water, 0.3-0.97% of the
polymer mixture, 0.6-3% of the magnetized
polyvinyl alcohol fibers, 1.5% of the serpentine
asbestos powder, and the balance of the aggregate.In the present invention, through mutual cooperation of the designed
polymer mixture, the magnetized
polyvinyl alcohol fibers, the aggregate and the serpentine
asbestos powder, the
water resistance is improved, the tensile strength of the cement stabilized macadam base can be effectively enhanced, the influence of temperature,
humidity and the reaction effect exerted by a running vehicle due to the
friction effect on the base can be weakened to a certain extent,
cracking is avoided, the drawing effect of external force can be continuously resisted after
cracking within a certain extent range,and the
cracking speed of the base is effectively reduced.
