【正文】 high Cheng, thickness is difficult to control, and make level repeatedly the surface is easy to emanate, at the same time the mixture is wasted more more too. Shanghai and Nanjing and owner , expressway of airport , according to standardize standard newly , put forward mixture concentrate factory on mix , import the paver not to pave the high demand built, it is that it can guarantee the mixture paved is even , the surface is levelled to put emphasis on importing the main reason of the paver, such indexes as Gao Cheng , verticalhorizontal slope , thickness ,etc. can meet the designing requirement . Is it import Model ABG paver is it build result to be best to pave , but domestic paver is it is it succeed in to pave to try on several times to practice has proved. To design thickness person who exceeds 30cm can divide into two is it build to pave , pave width control at 68m result better roughness having. Control the largest footpaths of the mixture and water content For improve at the basic level roughness and help paver is it build to pave, at the basic level mixture collect material heavy grain should be proper to reduce directly most. Because collect material grains of heavy footpath, mixture easy to is it emanate to produce, and to mix , pave wearing and tearing of equipment even heavy. So, reduce and collect the largest footpaths of material properly and favorable to the improvement of the paver homework and roughness of top surface at the basic level. In addition, the control of the water content of mixture construction is also very important, it influences the board body of the structure to take shape small that the water content is passed, it is difficult that the water content is too big to roll shaping, and apt to form the big wave of road surface, cause the roughness at the basic level to reduce, even cause the structure layer to shrink and fracture. Practice indicates , must begin from basic unit while improving the roughness of road surface of pitch , and the key of improving the construction quality at the basic level lies in adopting the superior construction machinery, if a grain of material factory of good stability mixes the equipment and imports the paver. Influence of 2 construction machinery homework Paver Accurate degree of basic steel wire and device It is in not constructing last layers of tightwire walking we, in, above layers of datum that walk snow prize last method, have received better result. Bottom surface layer before constructing, want piece draw handy on is it ask datum line , instrument of sensor to bear first(23mm steel wire rope), then it set up well all (from 10m),according to hanging wire that measure being the higher to confirm height , location of steel wire per of. Should measure , adjust conscientiously meticulously , check steel wire pulling force and can39。由于車輛在高速公路上高速行駛時(shí)產(chǎn)生的沖擊力大，國(guó)產(chǎn)橡膠板式伸縮縫經(jīng)受不了大交通量高速行車的沖擊。 施工縫的處理 瀝青路面施工縫處理的好壞對(duì)平整度有一定的影響，往往連續(xù)攤鋪路 段平整度較好，而接縫處的一個(gè)點(diǎn)數(shù)據(jù)較差。只有加強(qiáng)拌和站管 理，保證連續(xù)供料，運(yùn)用中途不停機(jī)加油，操作手輪換休息等辦法，做到每天早晨開機(jī)，晚上收工關(guān)機(jī)，中途力爭(zhēng)不停機(jī)，以確保路面攤鋪?zhàn)鳂I(yè)連續(xù)不間斷。 Ｃ。 壓路機(jī) 路面平整度好壞的關(guān)鍵在攤鋪機(jī)，但與壓路機(jī)的碾壓有著不可分割的關(guān)系。 Ｃ。 攤鋪機(jī)儀表性能及微調(diào)器的正確使用 路面標(biāo)高的控制是靠?jī)x表來實(shí)現(xiàn)的。 實(shí)踐表明，提高瀝青路面平整度必須從基層抓起，而提高基層施工質(zhì)量的關(guān)鍵在于采用精良的施工機(jī)械，如好的穩(wěn)定粒料廠拌設(shè)備與進(jìn)口攤鋪機(jī)。 重視基層平整，廠拌混合料攤鋪機(jī)鋪筑 二灰碎石半剛性基層的施工，過去習(xí)慣采用平地機(jī)作業(yè)，它的缺點(diǎn)是高程、厚度難以控制，且反復(fù)找平表面容易離析，同時(shí)混合料浪費(fèi)也多。中文 4180 字 畢業(yè)設(shè)計(jì)外文資料翻譯 系 部： 專 業(yè)： 土木工程（路橋） 姓 名： 學(xué) 號(hào)： 外文出處： 附 件： ； 。如誤差大于 10mm 則不平整度將更大，由此可見基層頂面的平整度對(duì)瀝青面層的平整度影響可謂舉足輕重。 另外，混合料施工含 水量的控制亦十分重要，含水量過小影響結(jié)構(gòu)的板體形成，含水量過大碾壓成型困難，且易形成路面大波浪，致使基層平整度降低，甚至導(dǎo)致結(jié)構(gòu)層收縮開裂。該裝置長(zhǎng) ，在攤鋪機(jī)前面的基準(zhǔn)梁上裝有 212 個(gè)可上下伸縮的 “ 雪撬 ” 板，后基準(zhǔn)梁上裝有 216 個(gè)可上下伸縮的橡膠輪，前后基準(zhǔn)梁在攤鋪機(jī)大臂處鉸接，可消除下層局部不平整，將原有路面縱坡 (通過前基準(zhǔn)梁獲得 )和新鋪層 (通過后基準(zhǔn)梁獲得 )的平均高程結(jié)合在一起，與 “ 走鋼絲 ” 及自制雪撬相比，攤鋪精度明顯提高，從而提高了路面平整度。Ｃ～ 90176。 此類校正行駛方向出現(xiàn)的小臺(tái)階，在曲線半徑較小的路段容易產(chǎn)生。 Ｃ，終壓完成時(shí)不低于70176。但在低溫季節(jié)施工，如供料不及時(shí)，攤鋪機(jī)待料時(shí)間過長(zhǎng)，雖然 ABG 型攤鋪機(jī)裝有防爬鎖，但因混合料溫度下降會(huì)引起局部不平整，而且自動(dòng)找平系統(tǒng)在每次啟動(dòng)后，需行駛 3～ 8m 后才能恢復(fù)正常，因此切忌攤鋪機(jī)經(jīng)常停機(jī)。因此，必須專人負(fù)責(zé)指揮倒車，嚴(yán)禁運(yùn)料車撞擊攤鋪機(jī)。滬寧高速公路與南京機(jī)場(chǎng)高速公路高度重視橋頭跳車問題，如采取先填路堤后鉆樁，采用工程性質(zhì)良好的材料填筑橋頭路堤，用手扶震動(dòng)壓路機(jī)處理邊角以減少橋頭路堤日后的沉降，收到了很好的效果。 附件 2：外文原文 Influence expressway pitch road surface roughness reason analysis and countermeasure In the construction of highway, because the pitch road surface has surface to levelled , drives a vehicle to resist the slippery , low in noise , short , characteristic of maintaining fortably , wearresistingly simply and conveniently etc. of cycle of constructing, and the extensive application of quilt.
