Abstract
The invention discloses a surface texture treatment method for an airport cement concrete pavement, and relates to the technical field of airport pavement construction. The method comprises the specific steps that a concrete pouring formwork is designed and manufactured, and the pouring formwork is erected; concrete is stirred and transported to a designated road paving position; the stirred concrete is unloaded, distributed and paved; the concrete paved between the formworks is vibrated and settled through a vibrator; the surface of the concrete is leveled, kneaded and leveled; the concrete surface is subjected to surface making process treatment; galling process treatment is conducted on the surface of the concrete; and performing pavement maintenance. By summarizing the relationship between the galling brush type and the measured values of the average texture depth and the friction coefficient and combining the environmental conditions such as wind power and temperature, the appropriate galling process time is selected, the phenomena that the texture depth of the pavement is insufficient, exceeds the standard or is not uniform and the like are solved, and the comprehensive anti-skid performance of the pavement is improved.
Description
technical field [0001] The invention relates to the technical field of airport road construction, in particular to a method for treating the surface texture of an airport cement concrete road surface. Background technique [0002] With the continuous and rapid growth of my country's aviation business volume demand, both military and civil aviation and general airports have entered the stage of large-scale construction. As we all know, the safety of aircraft taxiing is one of the important factors to ensure the efficient operation of the airport, and the surface performance of the airport pavement is the main factor affecting the safety of aircraft taxiing. Therefore, this requires us to put forward higher requirements on the surface performance of the airport pavement; in the construction process of the airport cement concrete pavement, the average texture depth is mainly achieved through roughening, groove carving and other processes, and this index is often affected by the...
