Cold Patch Asphalt Mixture

Cold Mix and Cold Patch Asphalt Mixture, which is not restricted by climate and with use with repair, has been widely used as inboard pit mending material, in the recent few years, as a result of the shortage of relevant evaluation guideline to evaluate Cold Patch Asphalt Mixture, the cold patch asphalt mixture perform differently because of the shortage of relevant evaluation guideline for evaluating its pavement performance, and people cannot been made the best of. its advantages, aim at this problem, this paper further studied pavement performance of the Cold Patch Asphalt Mixture. In this base, the paper established pavement performance evaluation system of Cold Patch Asphalt Mixture, and developed a new-style Cold Patch Asphalt Mixture.This paper selected many kinds of domestic Cold Patch Asphalt Mixture. According to massive interior experiments of cohesiveness, initial marshall stability, formed marshall stability, residual stability, freeze-thaw cleavage and track, the paper studies pavement performance of Cold Patch Asphalt Mixture, and analyzed mechanism and affecting factors of its strength form, and presented the methods of pavement performance tests, at the same time proposes evaluation standard on its pavement performance.According to thinner and additive's choice, we developed a new-style Cold Patch Asphalt Mixture. Through corresponding pavement performance experiments and observing testing pavement, indicate that the subject developed new-type Cold Patch Asphalt Mixture which is an excellent pavement mending material.The paper also analyzed production, storage and construction technology, and contrasted the economic and social results of Cold Patch Asphalt Mixture with hot-mix mixture in initial cost and later stage cost.
