Embodiment 1

[0029] Raw material weight ratio of SBS bituminous liquid for asphalt pavement pothole cold-mix repair material:

[0030] 0# Diesel 10% Ethylene Glycol 5%

[0031] 93# gasoline 8% SBS 7%

[0032] Antiaging agent BZ 8% Anti-stripping agent 0.4%

[0033] The balance is asphalt

[0034] The production process is as follows:

[0035] 1. Weigh 60% of the total formula weight of modifier SBS, diesel oil and gasoline, put it in a cylinder and seal it for dissolution;

[0036] 2. When the modifier SBS is completely dissolved into a viscous liquid, add it into the reactor and start stirring, slowly add the remaining 40% diesel and gasoline into the reactor, and stir for 1 hour;

[0037] 3. Put 1 / 2 of the asphalt into the reactor and stir for 2-2.5 hours;

[0038] 4. Put the remaining 1 / 2 bitumen into the reactor and stir for 2-2.5 hours;

[0039] 5. Add ethylene glycol and stir for 30-60 minutes;

[0040] 6. Add anti-stripping agent and anti-aging agent and stir for 30-60 minute...

Embodiment 2

[0043] Raw material weight ratio of SBS bituminous liquid for asphalt pavement pothole cold-mix repair material:

[0046] Antiaging agent OD 5% Anti-stripping agent 0.3%

[0047] The balance is asphalt

[0048] Produce according to the production technique of embodiment 1, the product technical index testing result that makes is as follows:

[0049]

[0050]

Embodiment 3

[0052] Raw material weight ratio of SBS bituminous liquid for asphalt pavement pothole cold-mix repair material:

[0053] 0# Diesel 7.5% Ethylene Glycol 4.5%

[0054] 97# gasoline 10% SBS 8%

[0055] Antiaging agent OD 10% Anti-stripping agent 0.35%

[0056] The balance is asphalt

[0057] Produce according to the production technology of embodiment 1.

Abstract

The present invention discloses SBS pitch fluid for repairing road pits and holes after cold mixing and its production process. The SBS pitch fluid has the material comprising diesel oil 7-10 wt%, glycol 4-5 wt%, gasoline 8-10 wt%, SBS 6-8 wt%, antiager 5-10 wt% and stripping resisting agent 0.3-0.4 wt% except pitch. The production process of the SBS pitch fluid is also disclosed. The SBS pitch fluid is liquid at normal temperature and low temperature and may be mixed directly before being used, so that it may be used conveniently all the year round without environmental pollution caused by heating pitch.

Description

technical field [0001] The invention relates to a building material, in particular to an asphalt pavement repair material SBS asphalt liquid and a production process thereof. Background technique [0002] There are more than 20 million cars in our country driving in 133×10 4 Km highway and 12000Km expressway, and most of them are asphalt roads. Over the years, the asphalt pavement has been damaged by natural wind, rain, sun, freeze-thaw and other disasters, so that the physical and chemical changes of asphalt and mineral aggregates continue to occur, gradually reducing the ability to adapt to climate change. Rapid increase, frequent traffic, heavy traffic load, heavy load repeated rolling, so that the local low-strength road surface is easy to cause cracking and damage to the road surface, with the water penetration of the road surface, the base layer and even the roadbed become soft, and potholes and pits appear. Potholes cause driving speed to drop, damage axles, increas...
