<p>Cement concrete pavement as a high-level pavement structure, will produce a variety of diseases, such as poor treatment, will affect the road function and life. Through years of practical experience, summed up as long as the treatment of cement pavement heat shrinkage joints, practical asphalt sealant, to seize the early crack road preventive maintenance irrigation joints, can effectively extend the life of cement pavement.</p>
<p>In general, the heat shrinkage treatment of cement pavement after preheating has two main points: to prevent water from dipping into the subgrade; to prevent foreign matter from entering the cracks caused by further expansion and peeling. For the airport, there are two other aspects of the crack treatment: some sealing material can be through the anti-fuel corrosion performance to avoid fuel corrosion of the road and grass-roots level, thereby reducing road pollution; can resist the nature of foreign matter through the sealing material to reduce the foreign body caused by Risk of harm.</p>
<p>Selection of sealing material Cement road surface cracks with a variety of materials sealed to choose from. Including rubber asphalt hot building, cold construction silicone, one-component or two-component anti-fuel oil products. In order to achieve lasting results, the appropriate product should be used. The cost of the sealing material is only 20% to 25% of the total construction cost.</p>
