Abstract
The invention relates to asphalt pavement using combination whose components weight percentage are as follows: rubber sand 50-80, super-polyester fiber 0-10%, natural fiber 0-10%, natural mineral powder 10-30%, and asphalt 5-15%. The adding granular material is easily added and controllable. The invention makes the rubber sand asphalt mixture pavement has high adhesion strength, compaction degree, property flexibility, low permeability and noise, good wear resistance, sliding resistance, thermal stability, durability, and long useful life.
Description
Technical field:
The present invention relates to road or airport pavement, the vibration and noise reducing bituminous pavement in the engineerings such as particularly a kind of highway, municipal administration, specifically a kind of composition of in road or airport asphalt pavement mixture, using and preparation method thereof that is adapted to.
Background technology:
Along with the raising of the speed of a motor vehicle and the raising of carload lot, tire and road surface contact noise become the overriding noise source.Porous asphalt pavement is one of representative Low Noise Pavement kind.Because China's dust pollution is more serious, hole stops up easily, and porosity is big simultaneously, and intensity is low, and poor durability, the particularly heavy duty of China's road, overloaded vehicle are many, influence pavement life.Through constantly test and research, rubber sand bituminous pavement has good anti-acoustic capability.There is (greatest combined thing 4mm) in rubber sand with the swollen raw state, still keeps the rubber good elasticity.Under the tire loading action, a possibility of rigidity contact of gathering materials reduces, and Rubber-Asphalt Pavement has more snappiness, and the tire vibration that pavement roughness causes reduces, and the carcass vibratory noise reduces.Rubber sand asphalt has the degree of compactness height, flexibility is arranged, perviousness is lower; Good wear resistance and anti-skid are arranged; Thermal and insulating performance is good, Heat stability is good.Problem is how to select the particle diameter of rubber sand, grating and additive for use, how to guarantee the bonding of rubber sand and sandstone material; The assurance pavement durability is good, and the life-span is long.Have following problem through test as single superpolyester fiber, natural fiber, natural ore powder of adopting easily in asphalt mixes and stirs the process of production: 1, breeze of Tian Jiaing and fiber enter in the dust collector with the dust in hot gas flow and the rubble pellet, influence addition content; 2, add the additive that mixes and stirs the storehouse at short notice and reach 3～4 kinds, easily produce and add mistake, can't guarantee to add the accurate of opportunity simultaneously.
Summary of the invention:
Purpose of the present invention just is to address the above problem, and a kind of composition of using in road or asphalt pavement mixture of being adapted to is provided.
Technical scheme of the present invention is to realize like this, a kind of composition that is used for bituminous pavement, it is characterized in that: described composition is made up of rubber sand, superpolyester fiber, natural fiber, natural ore powder and pitch, be particulate state, their weight percent is rubber sand 50～80%, superpolyester fiber 0～10%, natural fiber 0～10%: natural ore powder 10～30%, pitch 5-15%.
A kind of making method that is used for the composition of bituminous pavement, it is characterized in that: the making method of described composition may further comprise the steps, and A, is that 50～80% rubber sand, 0～10% superpolyester fiber, 0～10% natural fiber, 10～30% natural ore powder are placed in the feed bin with weight percent; B, heat, Heating temperature is a 90-120 degree Celsius, uniform mixing, and spraying into weight percent then is the atomizing pitch of 5-15%; The pressure of C, employing 0.1-0.5Mpa is pressed into the composition of 5-15mm particle diameter.
The present invention has been owing to increased the rubber sand and the natural ore powder of high share, makes this composition that is used for bituminous pavement have adhesion strength preferably, highly dense solidity, proper flexibility, lower perviousness; Good wear resistance and anti-skid are arranged; Good thermostability, weather resistance are arranged, and the life-span is long; The present invention has simultaneously overcome the problem that fiber, breeze fly into dust collector with dust and can't guarantee to add opportunity, easily adds, good control, does not disperse in mixing and stirring.
Embodiment:
Below the invention will be further described and provide embodiment
The present invention is a kind of composition that is used for bituminous pavement, it is characterized in that: described composition is made up of rubber sand, superpolyester fiber, natural fiber, natural ore powder and pitch, be particulate state, their weight percent is rubber sand 50～80%, superpolyester fiber 0～10%, natural fiber 0～10%: natural ore powder 10～30%, pitch 5-15%.During enforcement in order to reach better technical effect, superpolyester fiber and natural fiber have at least a kind of between the two, the particle diameter of rubber sand is 1.18mm～4.75mm, the chemical constitution of superpolyester fiber is an acrylic acid, the diameter of fiber is 10～14 μ m, length 4～6mm, the diameter of natural fiber is 45 μ m, length 1～6mm, and the particle diameter of natural ore powder is 3mm～8mm.
A kind of making method that is used for the composition of bituminous pavement, it is characterized in that: the making method of described composition may further comprise the steps, and A, is that 50～80% rubber sand, 0～10% superpolyester fiber, 0～10% natural fiber, 10～30% natural ore powder are placed in the feed bin with weight percent; B, heat, Heating temperature is a 90-120 degree Celsius, uniform mixing, and spraying into weight percent then is the atomizing pitch of 5-15%; The pressure of C, employing 0.1-0.5Mpa is pressed into the composition of 5-15mm particle diameter.
When rubber powder exists with the swollen raw state, still can keep the rubber good elasticity, under the tire loading action, a possibility of rigidity contact of gathering materials reduces, Rubber-Asphalt Pavement has more snappiness, and the tire vibration that pavement roughness causes reduces, and the carcass vibratory noise reduces;
The chemical constitution of superpolyester fiber is an acrylic acid, and fusing point is greater than 220 ℃, and trevira has high-tensile, good adsorption, high temperature resistant.As stabilization additives, improve colloidal structure and reinforced action is arranged;
Natural fiber through the wood fibre that chemical treatment obtains, has good adsorption, oil absorbency and high-temperature stability by natural timber, and the fusing point of natural fiber as stabilization additives, makes pitch oil film thickening greater than 250 ℃;
Natural ore powder, its main component are charcoal, hydrogen, sulphur, and the adsorptivity of itself and building stones is strong, antistripping is good, as cementitious additives, pitch force of cohesion are increased, and guarantee the bonding of pitch and rubber sand.
