Abstract
The cold stirred and cold spread road asphalt material is prepared with petroleum asphalt, polyurethane, resin, antifreezing agent, diluent, and coagulation accelerator, and through heating asphalt to 120 deg.c, dissolving resin, and mixing other components at 70-80 deg.c via stirring. The said asphalt material has good looseness for easy mixing, high peeling-off resistance with 80 % over contact area with stone material and high initial and ultimate stability, and is suitable for construction under various weather conditions, with the constructed road being able to be used immediately.
Description
Technical field
What the present invention relates to is the manufacturing technology of relevant pavement of road material, and particularly this ground surface material is the composition based on the macromolecular compound of pitch.
Adopt at present pavement construction mostly to adopt hot-mix asphalt mixture, produce, higher to temperature requirement during construction, and open to traffic immediately after the construction, product can not be reused, and environment is very big to construction infection.The ground surface material of cold mixing cold-application is a kind of trend of ground surface material in the road construction work, the material that each state all uses on this road surface of exploitation.The material that emulsified bitumen is to use at most: US5405440 utilizes to reclaim discarded pavement asphalt rubble adding emulsified bitumen and make cold mixed cold-laid pavement material, its emulsified bitumen is to be mixed by pitch and rubber polymer, and rubber then is the phenylethylene/butadiene polymkeric substance.US4928890 also provides a whole set of equipment and the method that reclaims pavement asphalt.Domestic pitch material research and development for cold construction also have many reports: the cold-applied asphalt mikture that is provided as CN1429863 (application number is 01145017.7) is by gathering materials, pitch, mixture by diesel oil, kerosene, gasoline and naphthenic acid constitutes, pitch is the 4-12% for gathering materials only, it seems that this cold construction material is not based on pitch.Asphalt cold repairing binding material and manufacture method thereof that CN1441004 (application number is 02133831.0) provides are to make performed polymer A with heavy oil, petroleum resin, make performed polymer B with solvent oil and styrene-butadiene rubber(SBR), make performed polymer C with diesel oil or kerosene, gasoline and thermoplastic styrene butadiene rubber, naphthenic oil.The additive and the pitch that make with these three kinds of performed polymers, mineral oil make product.Technology is quite complicated.Domestic in addition useful emulsified bitumen modification and make modified emulsifying asphalt concrete road surface it is said and can improve Pavement Performance conservation and construction cost.
Emulsified Asphalt Mixture is long because of its set time in the above prior art, and only is suitable for the hot weather construction, occurs cold cracking and the high unsteady state of mixing easily with Emulsified Asphalt Mixture behind the breakdown of emulsion.The cold mixing cold laid asphaltic material period of storage of domestic production is short, the adaptation provincialism is poor.Adopt import additive or import cold mixing cold laid asphaltic price height, its performance is short of to some extent to some particular requirement.
Summary of the invention
At the shortcoming that prior art exists, the present invention aim to provide a kind of low cost, technical feature comprehensively, can widely used cold mixing cold laid asphaltic material.
The raw material that the present invention uses has polyurethane(s), petroleum resin, coumarone resin except that pitch; Ethylene glycol, glycol ether; Hexadecyl trimethylene triamine, triethylenediamine, diesel oil or aviation kerosene etc.With diesel oil or aviation kerosene fluxed asphalt is the method that various countries generally adopt in the world today, yet certainly will destroy pitch ester and asphalt oil in the pitch, thereby make it lose original cohesiveness, thermoplasticity, thermoset, the present invention is remedied it by adding ester class thing (as petroleum resin, coumarone resin etc.).If singly adding petroleum resin is not nearly enough to improve dilution back bituminous performance, can't satisfy the road service requirements because its property of reasons in structure is very crisp because of petroleum resin.The present invention adopts polyurethane(s), by polyaddition reaction, thereby improves owing to the fragility shortcoming of using petroleum resin to bring, and further strengthens the adhesivity of cold laid asphaltic, has reduced its Temperature Susceptibility simultaneously, has improved its cohesion.For the defective that the tack that remedies between dilution back pitch and building stones reduces, adopt amine to add, can also promote polyaddition reaction, accelerated solidification simultaneously.For the cold mixing cold laid asphaltic is suitable for using under the low temperature, can add antifreezing agent therein.
Preparation cold mixing cold laid asphaltic material, it uses proportioning raw materials (W%) to be:
Pitch ... ... ... ... .. 55.0-78.0
Polyurethane(s) ... ... ... ..2.0-4.0
Resin ... ... ... .... 6.0-11.0
Frostproofer ... ... ... ... ..0.0-1.0
Thinner ... ... ... ... ..13.0-30.0
Setting accelerator ... ... ... ... ..0.0-0.5
In the above-mentioned raw materials, described pitch is petroleum pitch, and polyurethane(s) (hereinafter to be referred as urethane) is TDI type, MDI type, as 4500TA type, 4050A type etc.Described resin be in petroleum resin, the coumarone resin one or both; Thinner is aviation kerosene, diesel oil; Frostproofer is ethylene glycol, glycol ether (glycol ether) etc.; Setting accelerator is hexadecyl trimethylene triamine, triethylenediamine etc.
The preparation method of pitch material is: petroleum pitch is heated to 120 ℃, the resene material is added wherein dissolving, its temperature drops to 70～80 ℃ and adds thinners, urethane, frostproofer, setting accelerator down, and is even 35～60 ℃ of following stirring and dissolving.
In the practice, preferred composition of raw materials (W%) is:
Pitch ... ... ... ... ... 60.0-75.0
Urethane ... ... ... .... 2.0-4.0
Resin ... ... ... ... 7.0-10.0
Frostproofer ... ... ... ... ... 0.0-1.0
Thinner ... ... ... ... ... 14.0-27.0
Setting accelerator ... ... ... ... ... 0.0-0.5
In the resin with petroleum resin C5-C9 for well.
Frostproofer is can be no when use in not too cold area, and in the area use of heat, need polyreaction be finished, and needs road to solidify Shi Zeke sooner and adds setting accelerator, and at this moment the composition of raw materials best choice is following prescription (W%):
Pitch ... ... ... ... 60.0-71.0 64.0-75.0
Urethane ... ... ... ... ..2.4-4.0 2.0-2.4
Resene ... ... ... ... ..7.6-10.0 7.0-9.0
Frostproofer ... ... ... ... ..0.5-1.0
Thinner ... ... ... ... ..18.0-26.5 15.0-24.0
Setting accelerator ... ... ... ... .. 0.3-0.5
In preparation technology, above-mentioned two prescriptions are slightly different: after prescription 1 is 120 ℃ of pitch dissolving resins, add thinner below 80 ℃, 55-60 ℃ adds urethane, antifreezing agent and stirs and formed in 3 minutes; Fill a prescription behind the 2 pitch dissolving resins, add thinner below 70 ℃, 35-50 ℃ adds urethane, setting accelerator, stirs fast to form in 1 minute.
The present invention has overcome some defective that prior art exists, and by simple processing method, cheap cost is produced the high-quality cold mixing cold laid asphaltic compound that is suitable for various geographic climates.Its performance is:
1, free-running property :-10-40 ℃ free-running property is good,, can be easier to mix and stir with spade after 12 hours at-10 ℃ of constant temperature, and is identical with famous Canada " Ning Feng " board product free-running property.
2, antistripping: according to JTJ052-2000 " highway engineering pitch and asphalt testing regulation " by water-boiling method test, the present invention and building stones attached area reach more than 80%.
3, the Marshall stability of cold mixing cold laid asphaltic compound experiment is hit the compacting of solid yardage method by above-mentioned rules with light-duty, carries out the Ma Shi experiment immediately, incipient stability degree＞2.0kN, finally stability 〉=5.0KN.
