Step 7: based on a determination that optimal water consumption and optimum emulsification asphalt content formed Cold Recycled Mixture with Emulsified Asphalt.
In above-mentioned steps 1, analyze milling material and refer to, by sieving stepping after milling material sampling drying, be generally divided into 0-
The thin milling material of 9.5mm and the thick milling material of 9.5-31.5mm two grades, analyze thick milling material and the grating of thin milling material.The present invention's
In one embodiment, milling material sampling refers to use special milling machine that old asphalt pavement is carried out milling sampling.
In step 2 above, design grating be to milling material, newly gather materials, cement, breeze carry out grating according to a certain percentage
Synthesis, it is desirable to formate gradation composition meets emulsified asphalt cold renewal in " asphalt highway regeneration techniques specification " (JTG F41-2008)
The grading limit requirement of compound.In one particular embodiment of the present invention, give milling material, newly gather materials and cement close
Become a preferred embodiment of grating, as shown in Table 2 and Figure 1.As long as it should be noted that milling material, newly gather materials, cement, breeze
Formate gradation composition meet Cold Recycled Mixture with Emulsified Asphalt in " asphalt highway regeneration techniques specification " (JTG F41-2008)
Grading limit requirement, as long as then according to its component content in above-mentioned Cold Recycled Mixture with Emulsified Asphalt, mineral aggregate just can be with breast
Change Colophonium and water just can form the Cold Recycled Mixture with Emulsified Asphalt according to the present invention.
In above-mentioned steps 3, prepare emulsified asphalt and refer to the preparation method of above-mentioned emulsified asphalt.
In above-mentioned steps 4, the early strength test of Cold Recycled Mixture with Emulsified Asphalt is divided into brush test and rut plate
Coring test.Brush test refers to: 1) use gyratory compaction method forming diameter 150mm, high 75～the test specimen of 85mm；2) then will
Test specimen is placed in the climatic chamber (such as, the climatic chamber of LHS-100CL model) of 25 DEG C (degree Celsius), 70% humidity
Place about 4h and carry out health preserving；3) finally this test specimen is rotated under the conditions of such as outside 1.25 ° of angle and 600KPa experimental condition
40 times." asphalt highway regeneration techniques specification " (JTG F41-2008) requires that Cold Recycled Mixture with Emulsified Asphalt brush is tested
Mass loss rate≤2.0%.Rut plate coring test refers to: 1) trial-production thickness is the rut plate of 10cm, and wherein this rut plate divides
Rolling for twice and form, roll thickness is 5cm every time, and the mode that rolls is according to " Colophonium and Asphalt Mixture Experiment code " operation；2)
By the rut plate manufactured experimently 25 DEG C, the climatic chamber of 70% humidity places about 24h；3) finally to rut plate coring
Sample." asphalt highway regeneration techniques specification " (JTG F41-2008) requires integrity degree >=80% of rut plate coring sample.
In above-mentioned steps 5, determine that optimal water consumption refers to according to Cold Recycled Mixture with Emulsified Asphalt primary election grading method,
Emulsified asphalt content is set to about 4%, and additional water consumption is respectively adopted 1.0%, 1.5%, 2.0%, 2.5%, 3.0%, presses
According to the heavy compaction method of regulation in " highway earthwork test rule " (JTG E40-2007) T 0131-2007, most preferably use
