Abstract
The invention provides a damping pavement. The damping pavement comprises a surface course, a binder course and a base course in sequence, wherein a plurality of holes, which penetrate through the binder course, are formed in the binder course; and damping particles are poured in the holes. According to the invention, as the damping particles are poured in the binder course of the pavement, the advantages of the damping particles are effectively utilized to ensure the strength of the pavement and reduce the noise of the pavement.
Description
[technical field]
The present invention relates to pavement of road engineering, particularly relate to a kind of Damping pavement.
[background technology]
China's automobile pollution occupies third place in the world, along with the sharply increase of flow motor inevitably brings noise pollution.Especially city road traffic noise pollution is day by day serious, becomes large public hazards of China's urban environment gradually, seriously affects normal life and the physical and mental health of townsfolk." standard of environmental noise of urban area ", using 70dB, 55dB environmental noise abatement standard as daytime and night, exceedes this limit value, can produce harm to Man & Nature.The report that the World Health Organization delivers at Britain " New Scientist " weekly is warned, noise is engender tension and the major reason causing a lot of people's death, in Europe, in the people of heart disease or apoplexy death, 3% is had to be because caused by traffic noise, the whole world may have 210,000 people to die from noise every year.Domestic Medicine expert think, generally, will bring damage more than the noise of 60dB to the mankind, the noise of 80, more than 90 dB will make impaired hearing, and stays in the space of 100 ~ 120dB, and if nothing else, within one minute, will temporaryly becoming deaf, it is deaf namely to cause.How providing a kind of road structure that can meet technical performance tool decrease of noise functions again, is the focus of current pavement engineering development.
Current Noise Reduction Pavement, is all realized by making OGFC drainage type surface abrasion layer.This deck is compared with plain asphalt road surface structare layer, and the void content that improve bituminous mixture reaches 10 ~ 15%, utilizes loose structure to absorb sound principle to reach noise reduction object.The core technology on OGFC drainage type road surface adopts high-viscosity modified asphalt, prior art is all adopt modified rubber to improve the viscosity of modified bitumen, guarantee the adhesion strength of pitch and aggregate, thus ensure that macrovoid flexible pavement has decrease of noise functions concurrently while guarantee water stability, temperature stability.The defects such as it is single that this technology exists noise reduction means, and noise reduction is not obvious, and service life of road surface is short.
And damping particles is applied to road surface and there is not yet similar report.
