Asphalt pavement construction should pay attention to what problems

(1) Asphalt wax content is too high, the viscosity is lower than the lower limit, resulting in asphalt tensile strength is low, resulting in network or irregular cracks; asphalt and wax oil configuration than the actual situation may be. When the road has a certain slope,[url=http://roadmachinerysuppliers.com/wholesale/2051.html]highway maintenance for dummies[/url] we should pay more attention to the selection of friction and tear resistance. (2) new roads, rolling uneven or local water content caused by improper cracks; the new road with particular attention to pre-use, because the early process, the road to slowly adapt to local climatic conditions and artificial use conditions, a variety of Factors are often on the life of the road plays a significant role. (3) Now in the construction of the road when not only consider the width of the road, the surface of the contact area is too large, is not conducive to drainage, drainage is not good,[url=http://roadmachinerysuppliers.com/wholesale/3253.html]used vibrating road compactor[/url] infiltration subgrade, frost heave under the action of the formation of cracks; This is a common problem. It is important to keep the road clean. Hubei Cheng Li company's production of road vehicles can give you solve this problem. (4) limited by the soil, roadbed shrinkage shrinkage or shrinkage to produce horizontal cracks; I plant asphalt sprinkler in many parts of the construction process have encountered such a thing,[url=http://roadmachinerysuppliers.com/pavement/3415.html]concrete saw cutters[/url] the soil can not distinguish with the naked eye, the more advanced The higher the requirements of the road on the soil. General highway embankment thickness of not less than 20 cm.
