Embodiment 1
[0025] This example is to lay two layers of asphalt pavement, and the construction process will be described below in conjunction with accompanying drawing 1A.
[0026] 1) During the rolling process of the underlying layer 1, generally after re-compacting (the final pressing may not be performed), when the temperature of the asphalt mixture is 100°C and the degree of compaction is 95%, use a roller with concave-convex alveolar The road roller of the roller is used for rolling, and the flat underlying layer 1 is rolled into a concave-convex surface, and the longitudinal profile of the concave-convex surface is a trapezoidal tooth profile;
[0027] 2) Then spread sticky layer asphalt (ie, sticky layer oil) on the concave-convex surface of the underlying layer to form a layer of sticky layer 2; when spraying sticky layer oil, attention should be paid to controlling the amount of spraying to prevent deposits in the grooves Phenomenon;
[0028] 3) Pave a new asphalt surface layer ...
Embodiment 2
[0032] After the underlying layer is paved, use a milling machine to mill the flat underlying layer into a concave-convex surface. After cleaning, spray the adhesive layer asphalt on it to form a layer of bonding layer 4, and then the bonding layer Immediately after the curing, a new asphalt surface layer is paved, and the longitudinal profile of the above-mentioned concave-convex surface is an irregular polygonal tooth profile, as shown in Figure 2.
[0033] In the above-mentioned embodiment, the concave-convex surface of the underlying layer can be a continuous straight line 11 from a top view direction, as shown in Figure 3; it can be an intermittent straight line 12, as shown in Figure 4, and its arrangement can be Orderly or disorderly; if rolling is used, it can be curved strips 13, as shown in Figure 5.
Embodiment 3
[0035] After recompression of the underlying layer, use a gravel spreader to spread gravel or concrete prefabricated blocks with a single particle size specification on the surface of the underlying layer according to a certain coverage rate, and then use a light road roller for proper rolling to make the crushed stone or cement prefabricated blocks Part of it is embedded in the surface of the underlying layer, and then the sticky layer oil is spread, and a new asphalt surface layer is laid on it after the curing is completed. At this moment, crushed stone or prefabricated block 5 is embedded between the surface layers, as shown in FIG. 6 .
