In addition, open-minded at short notice if desired for color asphalt, can lay at short notice after the high temperature melt of employing more than 165 ℃ by when the mixing of pitch and pigment.But, owing to be at short notice by laying after the heat, therefore, be easy to sustain damage in the future, thus reduction of service life.
If use colourless pitch, mat formation though can carry out the colour of multiple color,, colourless pitch is the cost height not only, and its material than the plain asphalt fragility many, so be difficult to guarantee required ultimate compression strength.In addition, when summer temp raise, it is sticking sticky that the surface will become, and, can adhere in its surface dust, earth, coal smoke etc., thus original color lost.Based on above reason, utilize the colored road pavement of bituminous almost can not be suitable for.
The method for paving of laying for the mixture that utilizes Resins, epoxy and urethane to mix to form the back owing to reasons such as binding property problem between itself and the basic pavement material and material price costlinesses, seldom is used for road pavement.In actual life, usually only be applicable to mating formation of buildings underground parking etc.
[summary of the invention]
[inventing problem to be solved]
The present invention proposes for addressing the above problem.One object of the present invention is, a kind of color asphalt is provided, and (pigment) compares with other colo(u)r coating, can be under lower temperature condition, melt, thereby shorten total operation time within a short period of time.Simultaneously, not only can improve intensity, even and also can variable color under uviolizing.
Therefore in addition, another object of the present invention is, a kind of color asphalt is provided, and it uses ferric oxide, thereby weight is lighter, and can keep its natural color, has not only environmental protection, but also the advantage in significant prolongation work-ing life of difficult drop-off etc.Therefore, not only can continue to use for some time, and can improve the friction on surface, thereby guarantee the security of vehicle when scram.
[problem solution]
To achieve these goals, the invention provides a kind of for improving visibility is used for the surface ending after carrying out basic unit's laying color asphalt, it is characterized in that it is mixed by corresponding proportion by following several compositions and forms: pitch 4～7wt%, silica sand 30～40wt%, aggregate 50～60wt%, stone flour 2～6wt%, the coloured pigment 2～6% that is used to develop the color.Above-mentioned coloured pigment is mixed by corresponding proportion by following several compositions and forms: ferric oxide 30～40wt%, unsaturated polyester 50～60wt%, ultra-violet stabilizer 3～5wt%, antioxidant 3～4wt%, tensio-active agent 1～2wt%, rubber 1～2wt%.
At this moment, distinct more in order to make color, above-mentioned aggregate preferably uses colored aggregate.
[effect of invention]
As mentioned above,, compare, can melt within a short period of time, thereby shorten the activity duration with other coloured pigment according to the present invention.Not only can improve intensity, even and can variable color under uviolizing yet, also can be adjusted to the desirable intensity of user.
In addition, owing to use ferric oxide, so its weight is lighter, thus and can keep its natural color to play environmental-protection function.Reach about 3 times of bituminous concrete its work-ing life, so can save, and can continue to use for some time.In addition, because the friction height on surface, thereby can guarantee the security of vehicle when scram.
[embodiment]
Below, will be to being elaborated according to color asphalt of the present invention.
According to color asphalt of the present invention, be mainly used in school district that visibility has relatively high expectations or dedicated bus lanes interval, bike special lane, improving visibility, be used for the top layer after laying and finish up carrying out bituminous basic unit.
At this moment, above-mentioned color asphalt is carrying out after above-mentioned basic unit lays, asphalt emulsifying agent (adhesion coating Tack Coat) not, but after being coated with last layer priming paint, lay again, its thickness is more than the 30mm.
