Description
Technical field
The invention belongs to pavement material field, and in particular to a kind of permeable laying of roadway with environment-protecting color cementitious matter and its
Preparation method.
Background technology
Colorful Asphalt Pavement be by albino bitumen cementitious matter, gather materials, inorganic pigment etc. after mix by paving, roll and
Into, the type road surface has the function of abundant Colour selection, excellent physicochemical property, close and friendly environmental harmony, thus increasingly
It is subject to favor and payes attention to, is widely applied in park, cycle track, bus special line and landscape road etc..Should
The advantages of during for urban road is：Road surface beauty can be improved；Make function path subregion, easy to induce traffic；Improve and drive
The alertness and recognition effect of member, strengthens road passage capability and traffic safety.
Permeable road surface is the road surface of a kind of open gradation, large porosity, its voidage, can generally 15~25% or so
By drainage system at curb after surface gathered water is penetrated into impermeable stratum below in time, realize that the quick of surface gathered water is arranged
Go out, so as to mitigate the infringement of road ponding road pavement structure.In addition, the road surface of open gradation, large porosity can also strengthen road
Antiskid performance, while caused noise when can also absorb vehicle operation significantly reduces urban transportation noise, improves vehicle
Driver and the comfort of nearby residents.Therefore, chromatic cementing agent is applied to making permeable road surface, the then colour created
Permeable road surface will have the advantages that Colorful Asphalt Pavement and permeable road surface at the same time.Meanwhile this is also to the property of chromatic cementing agent
It can put forward higher requirements.
Proportioning and its system of the conventional art (CN106317758A) on open gradation, the chromatic cementing agent on large porosity road surface
Preparation Method, the special type chromatic bituminous cement is by C9 Petropols (20~120 parts), rubber oil (20~100 parts), SBS warm
Thermoplastic elastic (3~30 parts), SBR rubber class modified material (1~10 part), high density polyethylene (HDPE) (1~10 part), thermoplastic resin
Fat (1~13 part), high viscosity agent (2~20 parts), warm-mixing agent (1~10 part), polyamide (4~40 parts), vulcanizing agent (0.2~1
Part) and dispersant (0.1~0.5 part) totally 11 kinds of materials form, its preparation process is：After each raw material are mixed in a certain ratio
First stirring swelling 2~3h of development under the conditions of 120~140 DEG C, then high speed shear or colloid are ground under the conditions of 160~180 DEG C
1~2h is ground, then in development tank is sent into, extraordinary chromatic cementing agent is made after 2~3h is developed under the conditions of 170~185 DEG C.
As seen from the above analysis, the limitation of chromatic bituminous cement is prepared using conventional art and shortcoming is：
1st, preparation temperature condition is higher (170~185 DEG C), and consuming energy situation is serious；
2nd, using sulphur as vulcanizing agent, substantial amounts of sulfide will be produced in process of production, threaten staff's health,
Serious pollution environment；
3rd, conventional color bituminous cements is made of 11 kinds of raw material, wherein selected naphthenic rubber oil, thermoplasticity
The prices of raw materials such as butadiene-styrene rubber SBS, high viscosity agent and polyamide PA66 are high, are added significantly to production cost；
4th, the preparation process of conventional color cementitious matter (patent CN106317758A) is complicated, and technology is difficult to effectively be controlled
System：
(1) chromatic cementing agent of conventional color bituminous cements is made of 11 kinds of raw material, and raw material types are more, and increase is applied
Industry control difficulty, production cycle length；
(2) its production of conventional color cementitious matter divides three-procedure (first step stirring, swelling development；Second step high speed shear
Or colloidal grinding；3rd step swelling development, prepare), and differed with temperature the time required to each step, it is added significantly to produce
The complexity of technique and the difficulty effectively controlled.
Therefore, research and develop a kind of component is simple, production technology is simple, function admirable, environmental protection and cheap colour
Previous bituminous pavement is technical problem in the urgent need to address with cementitious matter.
The content of the invention
It is an object of the invention to provide a kind of high and low temperature performance is strong, adhesiveness is good, and anti-water damage and endurance quality are strong
Environment-protecting color cementitious matter for permeable road surface and preparation method thereof.
A kind of permeable laying of roadway environment-protecting color cementitious matter of the present invention, is made of the raw material of following mass percent：
