Asphalt pavement maintenance technology products since the glued seam pressure belt, the high grade highway is keep out!

Adhesive seam pressure belt adhesive seam pressure belt highway technology. Since the pressure belt manufacturer after years of operation, follow traffic continues to grow, will appear different degree of various diseases of asphalt pavement, the first performance for the cracks and potholes, pumping slurry, loose, vehicle dumpping and part of the driveway rutting, sections of the road there will be lack of strength of pavement structure, these diseases constitute the damaged road surface area is increased, flatness, greatly reduced by way of using the function, not only affects the driving comfort and safety, and can meet the inspection standards, affect the overall regional highway. Reasonable maintenance for highway use life, falling highway total life cycle maintenance cost, progress, highway service level and efficiency of resource using, it is of great significance, and can reach the function target and the cost benefit maximization. A horizontal longitudinal cracks, filling and sewing skills on crack seal treatment can prevent the rain water seeping into the pavement water harm, can also slow the development of the cracks, together is the most commonly used pavement maintenance skills. Commonly used irrigation sewing materials: heat hot asphalt, modified asphalt, emulsified asphalt, special glue, can direct irrigation seam, open CaoGuan seam, fill in tar sands, etc. 2, a thin layer of mask face skills through thin layer surface on the original pavement structure, to restore the original road surface appearance, service function, the thickness of 2 ~ 75 px, can finish SMA9. 5,Superpave9。 5 and OGFC9. 5. Three, NovaChip ultra-thin wearing layer using a dedicated paving construction equipment, a molding, thickness of 1 - 2 cm, gap graded, polymer modified asphalt mixture paved in a layer of beautiful seam large dose of polymer modified emulsified asphalt adhesive layer, can increase the resistance increase appearance, abrasion resistance processing appearance damage, reduce water cutting noise, etc. Four, the micro table place and slurry seal micro table place also can be called 'polymer modified emulsified bitumen slurry seal', is a polymer modified emulsified asphalt, aggregate, high quality water, add the seam an agent and filler ( Usually a cement) Must be scaled to form a mixture and using special cloth paving the road, the maintenance, rolling thin layer in the composition of the pavement. Its primary intention is to delay the onset of rutting and improve road conditions. Five, the fog sealing layer of fog seal is to dilute, slow setting a typical use of emulsified asphalt, it use asphalt distributor directly emulsified asphalt be sprinkled throughout the way appearance without cover, aggregate can progress anti-sliding function after sand blasting. First used in the treatment began to appear slightly pavement fatigue cracking, the loss of part of the fine aggregate, is the most useful means to this stage maintenance, and lower its cost. Fog seal can restore table oxidation and hardening of the asphalt road adhesion force, fill tiny cracks and open space, prevent road pavement meter of water infiltration, the low temperature from harm, to prevent pavement loose, the fog sealing layer can also be used to enhance the road surface color to distinguish between road traffic lanes. Six, HTP anti-aging thin layer correction HTP anti-aging thin layer will wear resistant aggregate directly into the emulsion, and participate in special ingredients to add the seam an agent to make the stability of suspension, and then through high voltage equipment evenly sprayed on the road, after eliminating the sanding and two step process with the roller compaction, and because full data package, relative sanding and roller compaction effect is more robust and stable. Maintenance process of this emulsion with sand ready-mixed greatly improved the shortcoming of the original fog seal technology, high adhesive bonding materials and high wear resistance of a combination of aggregate, the necessary to ensure the pavement anti-sliding function. Seven, the thermal regeneration after preheating of the original pavement milling planer and the newly added aggregate and asphalt mixing after paving rolling road use function to progress. But the equipment cost is higher, are not suitable for used in small-scale maintenance engineering. Eight, HAP HAP stone stone chips sealing layer sealing layer is in the spray liquid (HAP Polymer modified emulsified asphalt) According to must cooperation than add stone chips, kuangfen stir well after paving the road appearance of waterproof, resistance to sliding sealing layer. HAP protective layer first used in the asphalt pavement preventive maintenance and disease treatment, can shut down the fine cracks, slow shed particles extends the using life of asphalt mixture. HAP skill characteristics: good waterproof function; Strong adhesive force; Should not wear, anti-aging ability is good. But to fill cracks and active for a long time, when the crack, has serious rut, package, or structural problems, can be the solution. Nine, rubber asphalt stress absorbed layer AR - SAMI rubber asphalt stress absorbed layer ( AR- 萨米:应力吸收膜层间) Is made up of rubber asphalt and must be graded gravel material layered cloth and become a kind of flexible anti-cracking layer, the thickness of about 25 pixels. AR- SAMI has good function of resistance to deformation, the stress of the asphalt road surface cracks can be cut, and then cut or remove the reflective crack of asphalt pavement, increase the bonding effect between asphalt layer, is the world recognized antireflective cracks very useful solutions.
