【正文】 measurement must be accurate. Finally, there is fresh concrete to control the machine from one mode to the period of not more than the initial setting time of cement。 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。 As a result of this crack is through the thickness, so the rain will be along the crack under the Baptist the grass roots and the embankment, resulting in decreased strength of the foundation, and finally lead to the destruction of the entire road. 2Have vertical cracks Cement concrete pavement occurs during the operation of the vertical cracks are many reasons but the main reason is the question of intensity. Based on the longitudinal surface cracks caused by cracking The basis of the road is the road bed. Road, the road bed under the dead load generated, but also came under pressure from street traffic load. The basis of strength in the load, the inevitable occurrence of longitudinal cracking, if the roadbed vertical cracking occurred, it will reflex to the road up. The basis of the road bed can be divided into two categories is zero filling or excavation above the road bed is located directly on the natural soil。Cement Concrete Pavement On The Prevention Of Vertical Cracks 1 Preface Cement concrete pavement cracks a variety of forms. 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。槽底要清洗干凈，在槽底鋪設用A10mm鋼筋綁扎的10*10cm的鋼筋網(wǎng)，然后澆筑與原路面混凝土強度相等的小石子混凝土，保濕養(yǎng)生28天后開放交通。但采用這種方法處理，費用較大。如果是由于基礎開裂 而引起的路面開裂，則應在新澆混凝土板的全寬范圍內(nèi)加設單層或雙層鋼筋網(wǎng)，鋼筋網(wǎng)的規(guī)格一般用A10的鋼筋制成20*20cm間距即可。這種處理方法是將已開裂的混凝土板全部清除，保留橫向連接鋼筋。4裂縫的處理水泥混凝土路面縱向裂縫的處理可采用局部處理和全部處理的辦法。其次是混凝土拌和時控制施工配合比，各種材料計量必須準確。各種原材料的各項技術(shù)指標都必須滿足設計和有關(guān)規(guī)范要求。，保證混凝土質(zhì)量加強施工管理是確?；炷临|(zhì)量的重要途徑之一。振動棒是在攤鋪寬度內(nèi)等距離均勻布置，其振幅、頻率和功率都是可調(diào)的，克服了人工攤鋪不均勻的缺點。采用水泥混凝土路攤鋪機進行施工是提高混凝土板的均勻性、密性、保證其質(zhì)量的最有利辦法之一。(3)半填半挖路段半填半挖及舊路加寬路基施工，心須認真處理填方部分與舊路基或原山坡的接茬，在山坡上或舊路基邊坡上從填方坡腳向上挖成向內(nèi)傾斜的臺階。(2)零填及挖方路段在零填及挖方路段的基礎處理時，如果路槽范圍及路槽以下是普通土或
