I produced the polyamide resin -2 in order to solve the acid stone and asphalt poor adhesion, easy to peel off water, affecting the life of an additive. Through our years of research and development, the successful production of new road asphalt anti-stripping agent (polyamide resin) which applies to the current widespread use of pavement material by using (polyamide resin) anti-stripping agent, can greatly improve the road strength and increased abrasion resistance pavement for the resource-rich acidic stone paved road provides the conditions for high-grade. The experiment, (polyamide resin just add asphalt content of 3 ‰ -4 ‰), you can achieve the best anti-spalling effect. The polyamide resin by 3 ‰ -4 ‰ addition on the performance of a variety of different grades of bitumen were boiled comparative experiments, soaking Marshall stability residual indirect comparative experiments and splitting tensile strength of wet and dry experiments. The results are: I produced the polyamide resin adhesion to reach 4-5, immersion Marshall stability more than 93%, wet splitting tensile test indirectly more than 80% (dry specimen 60 ℃ thermostat 1.5h , 18 ℃ soaking 24h) heat aging performance polyamide resin is added to the asphalt after experiments with film oven method, the indicators are not lower than the original pitch, it will not adversely affect the durability of asphalt. Experimental results show that the polyamide resin produced by our company with 3 ‰ -4 ‰ added amount can reach the national eligibility criteria. At present, domestic and foreign anti-stripping agent has been widely used to improve the binding between asphalt and stone, to improve water stability, extend the pavement life, this can save a lot of road maintenance costs. I produced polyamide resin anti-stripping agent with similar products at home and abroad, cheap, can improve project quality, reduce project cost, with good economic and social benefits. Polyamide resin anti-stripping agent for viscous liquid, add a small amount, good thermal stability, resistance to water separation and strong advantages, particularly easy to use, can be directly added to the asphalt stirred use, does not change the construction process does not affect the construction progress. I produced the "Mastery" brand polyamide resin anti-stripping agent has in the country over the highway to be widely used, users generally believe that good performance, stable quality, is user trust products. Our company was founded in 2004, in terms of high-speed road additive materials have years of experience. New road company production of "Mastery" brand road asphalt (polyamide resin) -II anti-stripping agent is applied to the road surface material of the current widespread use. By using (polyamide resin) -II anti-stripping agent, can greatly improve the pavement strength, increased road wear, the adhesion between the acidic stone and asphalt grade increase from 1-2 to 4-5 for high-grade road paving to provide the conditions. At present, domestic and foreign anti-stripping agent has been widely used to improve the binding between asphalt and stone, to improve water stability, extend the pavement life, save a lot of road maintenance costs. I produced polyamide resin anti-stripping agent with similar products at home and abroad, and cheap, improve project quality, reduce project cost, with good economic and social benefits, and has worked in the country over the highway to get promote the application, users generally believe our product performance, quality and stability is user trust products. In recent years, the company's product range has been extended to a number of provinces of Shaanxi, Henan, Jiangsu, Qinghai, Gansu, Shanxi, Inner Mongolia and other municipal highway, user evaluation are quality products. The company is located in the East China Xi'an Baqiao market D311-2, the main Antistripping agent. Companies adhering to the "customer first, forge ahead" business philosophy, adhere to the "customer first" principle to provide our clients with quality services. Welcome!
