Description
CROSS REFERENCE OF RELATED APPLICATION
[0001] The present invention claims priority under 35 U.S.C.
119(a-d) to CN201610535117.9, filed Jul. 8, 2016.
BACKGROUND OF THE PRESENT INVENTION
[0002] Field of Invention
[0003] The present invention relates to a technical field of thin
overlay in pavement maintenance, and more particularly to a
low-noise anti-skid road surface processing method.
[0004] Description of Related Arts
[0005] Technical requirements for ultra-thin surfaces of the
pavement are as follows. Currently, new construction projects in
domestic road are slowed down, most of the roads go into the
conservation stage, and the cement pavement needs to be changed
from white to black.
[0006] Currently, the commonly used ultra-thin surface processing
technology includes fog seal with sand, slurry seal, micro-surface
processing, gravel seal, Novachip ultra-thin wearing course, and
epoxy coating. In spite that these technologies are able to meet
basic functional requirements, there are varying degrees of
defects. The fog seal with sand is poor in functionality, and only
has functions of water sealing and landscaping. The slurry seal and
the micro-surface processing are big in noise, so that the flaking
off easily appears. The gravel seal is big in noise, so that it is
easy to produce flying stones, thereby affecting traffic safety.
The Novachip ultra-thin wearing course and the epoxy coating are
high in cost and long in closed construction time, thereby
affecting traffic.
[0007] Therefore, the development of a new ultra-thin surface
processing technology has a wide range of market demand.
SUMMARY OF THE PRESENT INVENTION
[0008] In order to make up the shortcomings of the prior art, the
present invention provides a low-noise anti-skid road surface
processing method with fast construction and effectively cost.
[0009] The present invention is achieved by technical solutions as
follows.
[0010] A low-noise anti-skid road surface processing method which
takes a highway as a construction object and comprises steps
of:
[0011] (1) closing a construction section of the highway, and then
disease-treating and cleaning a road surface of the construction
section;
[0012] (2) through a construction vehicle, synchronously sprinkling
an interlayer interface agent, modified emulsified asphalt, an
anti-skid noise-reducing material, modified emulsified asphalt and
a surface protection agent which are successively distributed in a
multi-layer manner to the road surface, and forming an ultra-thin
overlay structural layer with a thickness of 2-9 mm on the road
surface; and
[0013] (3) after drying the ultra-thin overlay structural layer,
rolling the road surface for 1-4 times through a rubber tire
roller, and then maintaining, and finally opening traffic.
[0014] A preferred technical solution of the present invention is
as follows.
[0015] In the step (2), a weight ratio of the modified emulsified
asphalt, the interlayer interface agent, the anti-skid
noise-reducing material, and the surface protection agent is
(6-20):(1-3):(20-50):(1-5); the modified emulsified asphalt is
adopted as a bonding material and has an excellent road
performance; through a special construction vehicle, various
materials, which are successively distributed in the multi-layer
manner, are synchronously constructed.
[0016] The modified emulsified asphalt is prepared by mixing and
emulsifying an emulsifier, asphalt, a modifier and water with a
weight ratio of (1-3):(50-60):(5-10):(30-40), performance indexes
of evaporated residues of the modified emulsified asphalt provided
by the present invention are better than those of conventional
modified emulsified asphalts.
[0017] The interlayer interface agent is developed based on a
principle of surface chemistry, contains an emulsifier, a polymer
bonder and an asphalt regeneration agent/a cement reinforcing
agent, is capable of enhancing the permeation of the emulsified
asphalt to an original road surface, regenerating aging
asphalt/reinforcing cement, improving interlayer bonding force, and
avoiding flaking off. According to different materials, the
interlayer interface agent is divided into two types, namely, an
interlayer interface agent for asphalt concrete pavement and an
interlayer interface agent for cement concrete pavement.
[0018] The anti-skid noise-reducing material is prepared by mixing
basalt or a diabase stone material, with high elastic rubber
particles and a hydraulic cementitious material, and is able to
meet the anti-skid performance, ensure low driving noise, and
improve driving safety and comfort.
[0019] The surface protection agent comprises special resin,
polymer binder, anti-sticking agent, surface active agent, solvent
and water, and has functions of consolidating surface stones,
anti-sticking, wear and shear resistance and resistance to high and
low temperature, thereby effectively preventing the anti-skid
noise-reducing material from wearing off and avoiding the sticky
wheel phenomenon.
[0020] The durability, water sealing property and skid resistance
of the present invention are better than those of the fog seal with
sand and the micro-surface processing, and the driving noise
thereof is lower than that of the micro-surface processing and the
gravel seal. The present invention is able to prevent the flying
stones easily occurred in the gravel seal from affecting driving
safety, and overcome the flaking off easily occurred in the prior
art, so that it is a ultra-thin surface processing technology with
fast construction and effectively cost.
[0021] These and other objectives, features, and advantages of the
present invention will become apparent from the following detailed
description, the accompanying drawings, and the appended
claims.
