【正文】 ertical cracks started from the root. Front of the concrete pavement has been the main reason for cracks is analyzed, then the prevention of the occurrence of cracks on the need to take effective measures for its. The basic strength and the overall (1) Fill Embankment Construction of the embankment fill, it is important to the design requirements in accordance with norms and hierarchical placement, hierarchical RCC, degree of paction must meet the design requirements. In addition Subgrade must be fullfilling should not be at the construction site, the work of artificial joints caused by the vertical plane formed by the weak. (2) Zerofill and cut sections Zero filling and excavation of the foundation treatment section, if the scope of the road and the road trough trough following is a general soil or loose soil, the deal with the depth of groove should not be limited to the road, the road for the next slot (the way trough the top of the scope of the following 30 ~ 80cm ) also have to deal with, and its degree of paction and the road should be the same slot. For special emphasis on road transport, the depth of processing should also be deepened. (3) A halfdug halffilled sections A halfdug halffilled and the old roadbed construction of the road widening, should be seriously dealt with the heart filled with the old part of the slope of the roadbed or conjunctive phrase, in the slopes of the old roadbed slope or fill slope from digging up the steps into inward tilt , step width of not less than . Fill Subgrade paction degrees should be increased 1 to 3 percentage points. Construction of concrete pavement paver machinery Using cement concrete paver road construction is to improve the homogeneity of the concrete slab, Micronesia, and to ensure the quality of one of the best. Sliding mode on the paver, the concrete is vibrated by the vibration program vibration bar, and then vibrated by the vibrating beam. Vibrator in the equidistant uniform width paver layout, and its amplitude, frequency and power are adjustable to overe the shortings of artificial uneven paving. Therefore, the concrete slab paving uniform, dense, no weak points, or weak side. Strong construction management to ensure that concrete quality Strengthen the construction management is to ensure that the quality of the concrete one of the important ways. First of all, the quality control of raw materials. A variety of technical indicators of the raw materials must meet the design and the relevant regulatory requirements. Materials do not fail. Followed by the construction of concrete mixing mix control, a variety of materials
