Yet just after the road surface was built up, when the reaction between Resins, epoxy and the epoxy curing agent was not fully carried out, strength characteristic was poor, and had the problem that forms the wheel rut.
In addition, when with when wherein having added the material modified high-viscosity modified asphalt of thermoplasticity and compare, this bitumen-epoxy resin composition can provide the mixture that at high temperature has excellent durability, but exist them to lack elastic problem at low temperatures.
Therefore, the utmost point is wished to develop and is used to pave the way the pitch of purpose, especially bitumen-epoxy resin composition, there is improvement in it aspect the formation of anti-wheel rut, this is because strength characteristic the road surface is built up after is improved, and at high temperature resistance to flow of this asphalt mixture, splitting resistance and anti-aggregate dispersiveness aspect are improved at low temperatures.
In one embodiment of the invention, a kind of bitumen-epoxy resin composition is provided, its in shown in ratio contain: (A) 75-93wt% pitch, (B) 1-5wt% Resins, epoxy, (C) thermoplastic polymer of 6-20wt% toxilic acid modification, wherein the total amount of (A)+(B)+(C) is 100wt%, wherein aforementioned epoxy resins (B) is a kind of terpolymer, this terpolymer contains (i) rudimentary alpha-olefin, the (ii) lower alkyl esters of acrylic or methacrylic acid and (iii) glycidyl acrylate or glycidyl methacrylate, and these molecules have the Racemic glycidol end group.
In the further embodiment of the present invention, Resins, epoxy in bitumen-epoxy resin composition (B) is a kind of terpolymer, this terpolymer contains the n-butyl of (i) ethene, (ii) acrylic or methacrylic acid and (iii) glycidyl acrylate or glycidyl methacrylate, and these molecules have the Racemic glycidol end group.
In another embodiment of the present invention, Resins, epoxy in bitumen-epoxy resin composition (B) is a kind of terpolymer, this terpolymer contains the n-butyl of (i) 30-90wt% ethene, (ii) 10-70wt% acrylic or methacrylic acid and (iii) 0.5-30wt% glycidyl acrylate or glycidyl methacrylate, wherein the total amount of (i)+(ii)+(iii) is 100wt%, and these molecules have the Racemic glycidol end group.
In the further again embodiment of the present invention, the thermoplastic polymer (C) of the toxilic acid modification in bitumen-epoxy resin composition comprises: (iv) fusing point is 80-105 ℃ a polymkeric substance, therein ethylene-ethyl acrylate copolymer has been used the toxilic acid modification, with this polymer phase be 0.1-18wt% for the ratio of bitumen-epoxy resin composition, (the styrene-ethylene-butylene-styrene segmented copolymer (SEBS) of v) toxilic acid modification, with this polymer phase be that 2-6wt% and wherein (iv)+(total amount v) is 6-20wt% for the ratio of bitumen-epoxy resin composition.
As previously mentioned, although when with when wherein having added the material modified high-viscosity modified asphalt of thermoplasticity and compared, conventional bitumen-epoxy resin composition can provide the mixture that at high temperature has good resistance to flow, but shows the problem that has anti-aggregate dispersiveness and splitting resistance at low temperatures.
In the present invention, now be surprisingly found out that, can be by making the carboxyl reaction in epoxy group(ing) that has at low temperatures in the good flexible Resins, epoxy and the thermoplastic elastomer of using the toxilic acid modification, improve at high temperature resistance to flow, splitting resistance at low temperatures and anti-aggregate dispersiveness, thereby improve the dispersed and splitting resistance at low temperatures of anti-aggregate.
In addition, although when the reaction between Resins, epoxy and epoxy curing agent is roughly finished (when it hardens fully), conventional bitumen-epoxy resin composition can provide the road surface with good strength characteristic, but just after the road surface is built up, in the initial period that between Resins, epoxy and epoxy curing agent, reacts, strength characteristic is poor, and has shown that the wheel rut becomes problem area.
In the present invention, be appreciated that " road surface " comprises the pavement of road that is used for vehicle.
The thermoplastic polymer of toxilic acid modification used in the present invention (C) has high fusing point and elastic property, also Resins, epoxy had good reactivity with them, therefore just after the road surface is built up, in the initial period that between Resins, epoxy and epoxy curing agent, reacts, can improve resistance to flow (anti-vehicle rut forms).
Employed Resins, epoxy (B) is a kind of terpolymer in the present composition, this terpolymer contains the lower alkyl esters of (i) rudimentary alpha-olefin, (ii) acrylic or methacrylic acid and (iii) glycidyl acrylate or glycidyl methacrylate, and these molecules have the Racemic glycidol end group.Rudimentary alpha-olefin (i) optimal ethylene, propylene or butylene and ethene are special ideal, because it provides good low-temperature impact resistance.Low alkyl group preferable methyl, ethyl, propyl group or butyl and the especially preferred butyl of the lower alkyl esters of acrylic or methacrylic acid in (ii), flexible because it especially can give the asphaltic products. structure.
Preferably a kind of terpolymer of employed Resins, epoxy (B) in the present composition, this terpolymer contains the n-butyl of (i) 30-90wt% ethene, (ii) 10-70wt% acrylic or methacrylic acid and (iii) 0.5-30wt% glycidyl acrylate or glycidyl methacrylate, wherein the total amount of (i)+(ii)+(iii) is 100wt%, and these molecules have the Racemic glycidol end group.
If ethylene content is less than 30wt%, then low-temperature impact resistance may descend and if surpass 90wt%, then may be difficult to mix with pitch.If the content of the n-butyl of acrylic or methacrylic acid is less than 10wt%, then the bituminous water tolerance may descend and if surpass 70wt%, then shock resistance may descend.In addition, if the content of glycidyl acrylate or glycidyl methacrylate is less than 0.5wt%, then Fan Ying possibility is little, and the intensity of bituminous texture may descend, with if surpass 30wt%, then because reaction causes viscosity to raise quickens and can not guarantee after producing composition material competent usable time before road surface pavement.
Based on the gross weight of composition, the ratio of the Resins, epoxy of compounding (B) is preferably 1-5wt% in bitumen-epoxy resin composition of the present invention.If the content of the Resins, epoxy (B) of compounding within it above 5wt%, then causes the viscosity rising to be quickened owing to reaction and can not guarantee that the usable time before road surface pavement may be poor with on-the-spot operability after the generation composition material.
On the contrary, if, then reacting the possibility strength characteristic less and bitumen-epoxy resin composition that takes place less than 1wt%, the ratio of the Resins, epoxy of compounding may descend.
The preferred properties of Resins, epoxy comprise as JIS K 7210 described MFR (melt flow rate) for 8-15g/10min (200 ℃, 49N) and the second-order transition temperature that uses the dynamic viscoelastic method to obtain be no more than-45 ℃.
If MFR is less than 8g/10min, then on-the-spot poor operability and opposite is as if surpassing 15g/10min, then strength property decline.If the second-order transition temperature that obtains by the dynamic viscoelastic method is higher than-45 ℃, then according to Pavement Test Methods Handbook (NipponDorokyokai, 1988) the flexural strain of measuring decline and splitting resistance as low-temperature cracking-resistance in the 526th page of disclosed pliability test are poor.
In the present invention, wherein the ratio of the thermoplastic polymer of toxilic acid modification (C) compounding within it makes that its content in bitumen-epoxy resin composition of the present invention is 6-20wt%.
If the content of the thermoplastic polymer (C) of the toxilic acid modification of institute's compounding may be less than 6wt%, then sclerous reaction strength property insufficient and bitumen-epoxy resin composition may be not enough.In addition, if the content of the thermoplastic polymer (C) of toxilic acid modification surpasses 20wt%, then the viscosity of bitumen-epoxy resin composition itself raises and the operability possible deviation, quickens and the usable time that can not fully guarantee before laying because epoxy reaction causes viscosity to raise.
The maleation polyolefine, for example maleation polyethylene and maleation polypropylene, maleation vinyl-vinyl acetate copolymer, the petroleum resin of being produced by the petroleum fractions of toxilic acid modification, the ethylene-ethyl acrylate copolymer and the toxilic acid styrene-ethylene-butylene-styrene segmented copolymer (SEBS) of toxilic acid modification for example can be quoted the thermoplastic polymer as toxilic acid modification of the present invention.
The effective stiffening agent of the thermoplastic polymer of these toxilic acid modifications (C) as epoxy compounds of the present invention.Yet, in some instances, maleation polyethylene, maleation polypropylene, maleation vinyl-vinyl acetate copolymer and may at high temperature not have required thermostability and the low-temperature impact resistance aspect of the petroleum resin produced by the petroleum fractions of toxilic acid modification also may be lower by the petroleum resin that the petroleum fractions of toxilic acid modification is produced.In addition, maleation polyethylene and bituminous mixed performance also may difficulties.
The thermoplastic polymer of toxilic acid modification of the present invention (C) is wished most, this comprises the thermoplastic polymer that gets sour modification: (iv) fusing point is 80-105 ℃ a polymkeric substance, therein ethylene-ethyl acrylate copolymer has been used the toxilic acid modification, with this polymer phase be 0.1-18wt% for the ratio of bitumen-epoxy resin composition, (the styrene-ethylene-butylene-styrene segmented copolymer (SEBS) of v) toxilic acid modification, with this polymer phase be that 2-6wt% and wherein (iv)+(total amount v) is 6-20wt% for the ratio of bitumen-epoxy resin composition.
If the ethylene-ethyl acrylate copolymer fusing point (iv) of toxilic acid modification in the thermoplastic polymer of this toxilic acid modification is less than 80 ℃, then the space caves in and may occur the vehicle rut easily.On the contrary, if fusing point surpasses 105 ℃, then when storage contains the bituminous composition of ethylene-ethyl acrylate copolymer of pitch and toxilic acid modification, may separate, and not only may be difficult to guarantee the intensity on road surface itself, and the operability at transportation and scene also may become difficult.If there is the ethylene-ethyl acrylate copolymer less than the toxilic acid modification of 0.1wt%, then the strength property of bitumen-epoxy resin composition may descend.On the contrary, if surpass 18wt%, then viscosity increases and this may make that execute-in-place is relatively poor.
In addition, when the styrene-ethylene-butylene-styrene segmented copolymer (SEBS) of toxilic acid modification was included in the thermoplastic polymer of toxilic acid modification, then the ratio of the SEBS of the toxilic acid modification in bitumen-epoxy resin composition was desirably 2-6wt% most.If the SEBS content of toxilic acid modification surpasses 6wt%,, can not guarantee from producing usable time and the on-the-spot operability possible deviation that composition material is laid to the scene then because reaction can cause the viscosity rising to be quickened.On the contrary, if less than 2wt%, then may be difficult to react and exist the decline of bitumen-epoxy resin composition strength property.With regard to the performance of the SEBS of toxilic acid modification, according to the preferred 3-6g/10min of MFR and the preferred 5-15mg CH of acid number of JIS K7210 indication
3ONa/g.In addition, the vinylbenzene in styrene/ethylene-butylene ratio is preferably 25-35wt%.If MFR is less than 3g/10min, then the raise result that causes of viscosity is an on-the-spot operability possible deviation and if surpass 6g/10min, then exists the strength property of bitumastic type epoxy mixture to descend.If the acid number of the SEBS of toxilic acid modification is less than 5mg CH
3ONa/g, then reactivity may may descend by final strength lower and epoxy resin composition.On the contrary, if surpass 15mg CH
3ONa/g, then reactive possibility is higher, and viscosity raises and quickens, and may be difficult to guarantee usable time and on-the-spot operability possible deviation.
(A) has no particular limits to pitch used in the present invention, and condition is that it is that can be used for the paving the way pitch of purpose gets final product.Can use half oxidized bitumen among the described pitch of table 1 and Japanese Road Association Inc. the 51st page table 3.3.4 in " Outline of Asphalt Pavements " that on January 13rd, 1997, revision was published in JIS K 2207 easily.In addition, the extract shown in also can using under the furfural method of sand fallout pitch shown under the 308th page propane sand fallout (degravel) method of " NewPetroleum Dictionary " (1982) that Petroleum Society publishes and the 304th page easily.
Based on the total amount of the thermoplastic polymer (C) of pitch (A), Resins, epoxy (B) and toxilic acid modification, the amount of pitch (A) in bitumen-epoxy resin composition of the present invention is 75-93wt%.
In one embodiment of the invention, employed pitch (A) can comprise oil-filled pitch easily.For example, can use with the oil-filled pitch of petroleum-based solvent extract oil.With respect to the total amount of pitch and oil, can be 20-90wt% easily with respect to the asphalt content scope of the oil in oil-filled pitch.
Under those situations that employed therein Resins, epoxy of past is liquid, the possibility of leak of liquid appears.Yet aforementioned epoxy resins used in the present invention is granular solids at normal temperatures, so they can be to make the desired amount pack of composition material and to introduce when producing composition material and mixing.Therefore, easy processing and the degree of safety at production site also is improved.
The invention provides bitumen-epoxy resin composition, utilize said composition by increasing the just strength characteristic after pavement of road builds up, anti-wheel rut is improved and high temperature resistance to flow, low-temperature cracking-resistance and the anti-aggregate dispersiveness of asphalt mixture are improved.
The present invention further provides the purposes that foregoing bitumen-epoxy resin composition is used for pavement applications.

(2) use homomixer, under 170 ℃ mixing temperature, under the mixing agitator speed of 3000rpm, will mix 5 minutes the preparation bitumen-epoxy resin composition in 170 ℃ of liquid A that keep down and Resins, epoxy.
Then this bitumen-epoxy resin composition is mixed immediately the asphalt mixture of prescription shown in the preparation table 1 with the aggregate shown in the table 1 that maintains under 175 ℃.
(3) described in the 506th and 539 page of " the Pavement TestMethods Manual " that publishes as Nippon Doro Kyokai (Co.) (1988), after mixing, asphalt mixture is incorporated in the sample molding framework of the sample molding framework of Marshall stability test and wheel rut (tracking) test, and is incorporated into each sample framework in the baking oven under the temperature that maintains 170 ℃ and slaking 90 minutes.After slaking 90 minutes, from baking oven, take out these two samples, and regulate the sample temperature of Marshall stability sample to 155 ℃, and use the Marshall hammer to beat 50 times.
Regulate the sample temperature and the roll-in of wheel rut sample to 155 ℃.Use the sample of this sample then as initial intensity.From Marshall sample molding framework and wheel rut sample molding framework, take out the initial intensity sample then, and in baking oven 160 ℃ of following slakings 24 hours, the sample of final strength is provided.
Then, for embodiment 1-6 and Comparative Examples 1-9, as the method for the resistance to flow of the initial intensity sample of each bitumen-epoxy resin composition shown in evaluation table 1 and 2, carry out the wheel wheel tracking test described in " the Pavement TestMethods Manual " that publish at Nippon Doro Kyokai (Co.)
