Roadphalt All-weather Cold Paving Material
Company information
Founded in 2003, Shanghai Roadphalt Asphalt Technology Co., Ltd. is involved in developing and
marketing new technology, new materials and new techniques of road pavement. Integrating scientific research, manufacturing and sales, we are a nation-level high-tech enterprise with “new material for road pavement” as our core competence. Our company owns research labs, a large-scale manufacturing and processing plant and a nationwide sales network. We cooperate with world renowned scientific institution for pavement, and learn from established scientific results and application technology from other countries. We also join hands with the Key Laboratory of Road and Traffic Engineering of the Ministry of Education, Tongji University on long-term collaboration to develop such products as colored pavement material, road maintenance material, special asphalt and asphalt processing equipment. Being “science-led and service-oriented” is our principle, and we established the brand of “Roadphalt”.
Description
Roadphalt all-weather cold paving material is a kind of high-tech road patching material, mixed and prepared by using Roadphalt high-performance cold paving additive, asphalt and aggregate according to certain processing technology, with an appearance of black grain-like solid, slight petroleum smell, insoluble in water, insensitive to motive impact and static electricity, and with stable properties. The product can be used in all weather, suitable for patching all kinds of road pavement in all weather and environment (even in water), and it can ensure to repair holes, functional ruts, coats or the edges of cement concrete perpetually and simply use without the need of mixing or adhesive layer.
Advantages and Primary Uses
1. Suitable for all weather and environment
Roadphalt all-weather cold paving material has a wide applicable environment temperature range of -30℃~50℃, with very excellent water-proof property, and it can be constructed in raining/swimming weather and ponding holes.
2. Simple construction
No adhesive oil is needed during repairing and the prepared material can be taken when used, and no heavy-duty equipment is needed. According to the different repairing situation of pavement, impact compaction, artificial compaction or car’s tires compaction can be adopted. Moreover, no traffic closure is needed for the areas repaired by using roadphalt all-weather cold paving material, vehicular traffic can be opened
immediately, which may greatly ease the traffic pressure caused by repairing construction for roads.
3. Good repairing quality
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.
4. Being prone to storage
At normal atmospheric temperature, the sealed fill-bag finished product can be stored for as long as 12 months.
5. Being green and environment-friendly
No dust and black smoke will be produced during the application and production of Roadphalt all-weather 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.
6. Wide applicability
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 maintenace.
7.High material utilization
It can be taken for use at 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.
Process of construction
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.
2. 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.
3. Compact
Thoroughly press the pavement compacted to get a sound base, the better pavement compaction method is to use steel-wheel road roller or vibrating road roller, and for small holes, shovel can be used to press it compacted. The repaired holes’ surfaces 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.
Conventional question
1.How to dealing with the groove/potholes?
Just simple treatment, the holes/trench with gathered water can be filled directly
2.How about the storage?
The fill-bag sealed finished product can be stored as long as one year at room
temperature
3.After construction, how long can open the traffic?
Putting the matreial into holes and then compaction slightly.That means the traffic is opened immediately after the patching is finished
4.How to choose a suitable mixture gradation?
5,How to calculate the material dosage?
Material dosage calculation:
length x width x thickness x density (2.4)
for example:
a length and width of 50cm, thickness of 5cm pit, what is the amount of cold material ?
0.5×0.5×(
0.05+0.02)×2.4=42kg
Packaging:
25kg/bag, 1ton/pallet
Payment:
T/T , before delivery , buyer pay in full.
Shelf life:
The full-bag sealed finished product can be stored as long as half of one year at room temperature.
