<p>To provide the public with a better travel environment, to maximize the life of the road, Linfen Highway Branch adhering to the "scientific conservation, prevention and maintenance,ireland asphalt pavement sealing machine standardized management" principle, and actively explore the winter road preventive maintenance of new models, from small road irrigation Sewing to start, adhere to the "fuss" to achieve the winter winter to the current winter busy transition, creating a suitable for the characteristics of Linfen highway scientific conservation methods. "Small slit does not make up, big crack hardship", as if the human wound, if not promptly dealt with, will penetrate the bone marrow, causing serious illness. Tests have proved that the quality of road conditions to a certain extent, after taking conservation measures, the funds will be spent several times preventive maintenance, and large and medium-sized repair half-width or even full-width closed traffic, will bring inconvenience to the public travel.</p>
<p>"Machine can not afford to lose no longer come," the choice of filling time for the effect of irrigation joints play a vital role. From the degree of cracks: to the winter, affected by low temperature, pavement cracks faster than the spring and autumn season, the width and depth will reach the maximum. But at this time asphalt material brittle and viscous,circuit board sealant spray poor mobility, difficult to carry out construction operations. If you can overcome the shortcomings of the asphalt material, winter is the ideal season for road filling. From the road to see the water: the traditional understanding of the people generally believe that the greatest damage to the cracks in the rain, so the pits are generally arranged in the spring and autumn. But with the Linfen branch over the years to explore the study found that the winter snow melt water on the road damage even greater. The main reason is: snow melt water flow rate is slow, into the cracks will be a lot of the amount,asphalt paving material cost coupled with the impact of winter temperatures will be repeated frost heave, making the width and depth of the cracks gradually increased to speed up the road damage. From the economic general account to see: spring and summer although the two branches of the infusion of funds less, but in the winter, with the epidermis and grass-roots temperature contraction, the original cracks will be cracking again, will cause the next year's second investment. Winter irrigation joints a one-time investment is relatively more, but after the general treatment will not change the general expansion, to avoid the re-investment. Therefore, it is very important to do a good job in winter irrigation, and will play a multiplier effect.</p>
<P>"There will be filling, irrigation must meet the standard", winter irrigation joints materials, equipment and technology choices need to crack a major problem. In order to do the work of the winter irrigation joints do fine, played with the effect of point to the surface, Linfen Branch carefully deployed on January 24 held a winter road maintenance site will be from Yicheng, Hongdong, Houma, Puxian four roads Section of the actual exercise,asphalt paving precautions problems in the irrigation joints materials, conservation equipment, construction technology in three aspects made a useful attempt.</P>
