·Main Features<br />
1.suitable for all weather and environment<br />
Roadphalt all-weather cold paving material had a wide applicable environment temperature range of -30-50 degree,with very excellent water-proof property,and it can be constructed in raining/swimming weather and ponding holes.<br />
2.Simple construction<br />
No adhesive oil is needed during repairing and the prepared material can be taken when used,and no heavy-duty equipment is needed.After repairing roads,traffic can be opened immediately.<br />
3.Good repairing quality<br />
Roadphalt all-weather cold paving material has very strong anti-aging property and cohesive property,the repaired holes are not prone to peeling off and crazing etc bad phenomenon,do not need to be repaired repeatedly,and service life can achieve to 10 years over.<br />
4.Being prone to storage<br />
At normal atmospheric temperature,the sealed fill-bag finished product can be stored for as long as two years.<br />
5.Being green and environment-friendly<br />
No dust and black smoke will be produced during the application and production of Roadphalt all-weather use cold paving material,moreover,the finished products are not soluble in water,therefore the atmosphere and underground water will not be polluted,which is beneficial for environment protection.<br />
6.Wide applicability<br />
Roadphalt all-weather cold paving material can be widely used in highway,general roads,municipal roads and facilities,airports,bridge expansion joints and other road repair and maintenance.<br />
7.High material utilization<br />
It can be taken for use any time according to practical usage,and the rest material can be continued for use in next repair,which may not lead to material waste and realize 100% utilization.<br />
·Product Application<br />
Roadphalt all-weather cold paving material is simple and efficient for use,and provides an economic,simple and permanent solution for each environment,for not only holes,functional ruts,seam repair,edge maintenance or surface repair(leveling process),and even small mask surface.<br />
Roadphalt all-weather cold paving material can be used in all-weather(regardness of sunny or rainy days/cold or hot days)and can still maintain good usage property though it has a longer storage life.<br />
Roadphalt all-weather cold paving material can be used for repairing the surface of both asphalt and cement concrete without need of bonding oil,and even used in water.The traffic opens immediately after construction is complete.<br />
·Permanent repair of pits and pit covers<br />
Roadphalt all-weather cold paving material can be used to repair any pit cover very successfully.When using cold paving material,bonding oil is not needed in general due to the good cohesive capacity of Roadphalt all-weather cold paving material itself.For holes with water,Roadphalt all-weather cold paving material can be filled derectly and the water is not needed to remove first,meanwhile Roadphalt all-weather cold paving material with most cold pavement seal coat materials,pouring sealant are miscible,the repaired pavement can also keep contact,cohesive property and provide enough usage property.<br />
<br />
·Repairing functional ruts and trenches<br />
In the construction projects of municipal roads or highways,it’s necessary to dig out trenches on pavement to lay out the pipelines or construction tap water or drainage pipes,while using hot stirred asphalt mixture for repair may bring about many problems.In many cities,millions of money is cost on curing and patching the trenches every year.If reasonable procedures are followed,Roadphalt all weather cold paving material can be taken as a kind of permanent trench-patching material.As all the other materials,Roadphalt all-weather cold paving material should form a tight,solid basis without sinkage,and thus it can prevent the failed patching for trenches caused by sinkage,ruts or transposition.<br />
To get the best compaction effect,the thickness of Roadphalt all-weather cold paving material should not surpass 5cm in every paving construction.The best compaction effect can be obtained by applying the vibrating roller with steel wheel.If the steel wheel roller is not suitable for the trenches to be rolled,iron ram can be used manually to compact the trench.<br />
The consolidation of Roadphalt all-weather cold paving material can reach as high as 40% before getting to the highest density.When patching a 5cm deep hole,the height of Roadphalt all-weather cold paving material should be 2cm higher than the original pavement,to make the best compaction degree achievable.<br />

<br />
·Process of construction<br />
1、Sweep:Generally,the gravel and waste residues in and around the holes to be repaired should be removed thoroughly,and there should not be slurry or gravel in holes.The holes or surrounding trenches in highways or municipal roads should have regular edges,and for removing waste residues,the solid hard surface should be seen before construction.
Fill:Fill enough Roadphalt all-weather cold paving material into the holes until the material is 1.5cm or so higher than the ground surface.For repairing highways or municipal roads,the input amount of cold paving material can be increased by 10%-20% or so,after filling the holes over,the central site of the holes should be a little higher than the surrounding pavement and assume arc shape.
Compact:Thoroughly press the pavement compacted to get a sound base,the better pavement compaction method is to use steel-wheel road roler or vibrating road roller,and for small holes,shovel can be used to press it compacted.The repaired holes’surface should be clean and regular without wheel marks.The periphery and edges of the holes must be pressed compacted and without loosing.The degree of repair compaction should reach 93% above for common roads and 95% above for highways.
4、 Open the traffic:after the repair is complete,the road should be smooth,flat,no wheel tracks,no loose after forming the road.<br />

·Conventional<br />
1、 How to dealing with the groove/potholes?<br />
Just simple treatment,the holes/trench with gathered water can be filled directly.
How long does the storage shelf life of the product?
The fill-bag sealed finished product can be stored as long as one year at room temperature.
After construction,how long can open the traffic?
Putting the material into holes and then compaction slightly.That means the traffic is opened immediately after the patching is finished.
How to choose a suitable mixture gradation?

DurabilityThe lifetime is as long as 10 yearsOrdinaryOrdinary<br />
Consume of energyThe stone materials are generally not required to be heated,and the temperature of asphalt is low,so the energy is savedThe stone material and asphalt are required to be heatedAmount of asphalt consumed is 10% less than that of the hot patching material,and the stone material is not heated,and the temperature of asphalt is high<br />
Material consumeRepeated repairs are reduced and material is saved;the shutdown cost caused by winter and raining weather is reducedWaste is caused by taking larger amount of material to keep it warm;and the damage aggravates due to the patching cannot be constructed at any timeGenerally the patching can be constructed in time,and the amount is taken according to the actual need.The cost on the shutdown of the construction and the machines is reduced to some extent<br />
Social benefitPatching is constructed at any time to maintain the pavement fresh all the time,which makes the traffic smooth,reduces traffic accidents and the patching times,and prolongs the serving life of the roadsThe patching cannot be constructed at any time,which aggravates the impairment,influences the traffic,and reduces the serving life of the roadsThe patching time is a little long,which influences the traffic<br />
