Example 2

Aiming at the problem that the road surface noctilucence performance and service performance of a flexible full-thickness noctilucence road surface paved in 2018 are reduced to a certain extent due to the influence of road surface pollution and road surface use, the maintenance method is adopted for road surface maintenance.

In this example, in step S12, washing is performed by water washing and negative pressure adsorption.

In the step S20, the thickness of the noctilucent function recovery layer above the original road surface is 1.2mm, and the depth of the noctilucent function recovery layer penetrating into the original road surface is 2.3 mm.

In the step S21, in the emulsification of the thermoplastic transparent binder, the solid content of the thermoplastic transparent binder is 62%.

TABLE 2

Item	Unit of	When new construction is made	Before maintenance	After curing	Recovery situation

In the step S41, the anti-aging layer 40 is sprayed with the anti-aging varnish, which is anti-aging transparent fluorocarbon resin varnish.

In said step S42. The pavement maintenance condition is sunny day, and the maintenance time is 4.5 hours.

TABLE 3

It should be noted that the road surface maintenance scheme in this example is shown to restore the luminous performance of the road surface, while the road surface still has excellent road performance such as water seepage and skid resistance after 1.5 years, and the luminous performance after 1.5 years is obviously higher than that of a newly-built flexible full-thickness luminous road surface after two years.
