s1: the method comprises the following steps that a mortar kneading process is started, firstly, a roller (1) for mortar on the surface of pavement concrete is flatly kneaded, two operators of the roller (1) hold hand rings to transversely spread traction rods towards two sides respectively to enable hexagonal metal ring buckles at traction joints to clamp the end of the roller (1), and thus when the roller (1) is dragged again, the roller can not roll to achieve the effect of flatly kneading;
s2: after the step of flatly rubbing the roller (1), performing second-step construction, namely staggered rubbing, on mortar on the surface of the concrete, wherein two operators hold the hand rings to repeatedly do repeated actions in opposite directions, so that the roller (1) swings back and forth with the middle point as an axis and the two ends controlled to be between 25 and 35 degrees, and slowly moves forwards according to the actions, and the staggered rubbing has the effects of further improving the uniformity of the mortar and realizing leveling of the system surface of the pavement slab;
s3: the third step of the process is rolling and kneading, which is similar to the first step but has different purposes and effects, an operator keeps the bracelet to be parallel to the concrete slab longitudinally as much as possible, so that the moving resistance of the roller (1) can be reduced, the roller (1) can roll smoothly, rolling and kneading are carried out for three to four times, sand with the particle size of more than or equal to 2.36mm is embedded below a three-millimeter pulp layer, the rolling and kneading play a role in supporting and lifting, and the mortar thickness uniformity is ensured and paving of the next concrete plastering process is also well carried out;
s4: in the collecting operation process, the position of an arc-shaped limiting plate (806) on an auxiliary inclined plate (7) is adjusted according to the width of cement laid on two sides of cement concrete, so that the distance between the arc-shaped limiting plate and the width of a cement pavement actually laid is adjusted to be equal, when the slurry kneading work is carried out, redundant slurry can be ensured to enter a collecting groove (802) for centralized treatment, waste is avoided, the stability of the slurry limiting and collecting work can be improved through the arranged mounting component (11) and the locking component (12), the slurry limiting and collecting work is very convenient to replace, the operation is convenient, the use flexibility is high, and the construction is facilitated;
s5: and thirdly, after the construction method of the roller (1) is completed, detecting the mortar thickness on the surface of the pavement concrete slab, and measuring the intersection point of two diagonal lines of one slab and the points near the two ends of the diagonal line by adopting a five-point measurement method, wherein the five-point measurement method can control the mortar thickness and uniformity more strictly and prevent the phenomenon of insufficient local mortar thickness.
