Therefore, in order to maintain the roughness of the pavement and improve the skid resistance and the wear resistance of the pavement, measures must be taken to carry out skid resistance treatment on the pavement, the traditional mode is to adopt mechanical roughening to increase the roughness of the pavement, but the mechanical roughening is influenced by various factors (embossing time, concrete vacuum dehydration and texture depth uniformity) in the implementation process, so that the skid resistance treatment effect is poor, and the mechanical roughening reduces the wear resistance and the overall aesthetic property of the pavement.

Detailed Description

As shown in figure 2, the antiskid groove structure of the fabricated pavement is an antiskid groove hole 5 similar to a diamond shed with an inclination angle of 45 degrees, the hole depth is 2-4mm, the section is tapered, the upper part is wide and the lower part is narrow, the size of the upper section is 25 mm/8 mm, and the size of the lower section is 23 mm/6 mm.

The antiskid groove structure is formed by pouring concrete with the concrete strength of C40, single diamond-shaped shed antiskid groove holes 5 with similar inclination angles of 45 degrees are arranged in rows on the driving surface of an assembly type road deck board 1 and are uniformly distributed in a multi-row parallel mode, and the included angle between the length direction of the assembly type road deck board 1 and the long diagonal direction of the diamond-shaped shed antiskid groove holes 5 is 45 degrees; the long diagonal directions of the two adjacent rows of the diamond shed anti-skid slotted holes 5 are opposite (as shown in figure 4); the principle of the structure is that the friction resistance coefficient is increased by changing the surface roughness of the road slab 1, and the friction contact area is also enlarged to a certain extent, so that the relative friction force is increased.

The specific implementation process of the structure is as follows:

step 1, manufacturing a mould, selecting a batch of high-strength wear-resistant steel plates with the size specification of 6m x 2m x 6mm, simultaneously processing and producing anti-skid protrusions with single diamond sheds with similar inclination angles of 45 degrees arranged in rows at equal intervals on the steel plates, wherein the anti-skid protrusions correspond to anti-skid groove holes 5, the hole depth is 2-4mm, the cross section is gradually reduced, the upper width is narrow, the size of the upper cross section is 25mm x 8mm, the size of the lower cross section is 23mm x 6mm, marking positions of a hoisting hole 2 and a grouting hole 3 on a road plate on the steel plates, and cutting reserved holes.

And 2, taking the convex side of the patterned steel plate as a bottom die of the fabricated pavement slab 1, and assembling the integral die on a die table.

And 3, putting the pavement slab steel reinforcement cage into a mold, positioning the position of the embedded part by using a tool, adjusting the thickness of a protective layer between the concrete and the steel reinforcement cage, and ensuring the accurate size and position of the assembled pavement slab anti-skid groove structure.

And 4, after a series of process steps of concrete pouring, vibrating maintenance, hoisting and demolding and the like, flushing redundant concrete residues on the surface of the pavement slab by using a water gun, wherein the flushing water pressure is not too high, and the mold can be recycled after being cleaned and maintained.

And 5, when the assembled road slab 1 is stored in a storage yard, the flexible long sleeper pad is used for placing, so that the damage of the antiskid groove structure due to the influence of factors such as transportation, hoisting and the like is avoided.

And 6, repeating the operation steps 2-5 to produce the fabricated pavement which meets the technical requirements of road construction and is provided with a durable anti-skidding groove structure.
