There is prima facie net crack, horizontal cracks, vertical cracks and so on. Life on the road most affected among the longitudinal cracks. Such cracks are usually the central line of the lane, in the event that a few or dozens of pieces of concrete slab for cracking, and cracks throughout the thickness。 the stability of poor letter of appointment. Therefore, dead load on the road and the role of motor vehicles under the dynamic load, basic first vertical cracks. Cement Concrete Pavement strength Cement Concrete Pavement can not be sufficient if the arrival of the ability to engage in bending, then the role of load in the car, the inevitable destruction of produce, such as longitudinal cracking. Cement Concrete Pavement with low intensity, there are two major reasons, one degree less than concrete Taiwan design value。 Vertical cracks in cement concrete pavement may be the deal with all of local processing and handling methods. Before processing, the cracks must be generated to investigate the cause analysis, to determine what causes and then determine what approach to use. All processing This approach is to crack the concrete slab has been cleared of all to retain the horizontal connecting bars. If there is damage to the grassroots level appropriate to deal with, and then repoured with the original surface of the concrete slab, such as strength. If that is the basis of cracking due to the road surface caused by cracking, it should be in the new fullcast concrete slab added to a wide range of singlelayer or doublereinforced, reinforced the general specifications of the steel used Φ10 made to 20 * 20cm spacing . This method is suitable for a variety of reasons arising from the road surface cracking. The use of this approach, the cost of the larger. Partial treatment Local processing is in the cracks on both sides of the range of not less than 50cm cutting a groove, deep groove thickness of ~ times the slot on both sides must be neat, should be cut cutting machine. Clean bottom, laying in the bottom Φ10mm reinforced with banding of 10 * 10cm steel net, and then poured with the same intensity of the original concrete pavement pebbles concrete, moisture transport
