级配砂砾路面底基层施工方案
一、装载机4台，振动压路机1台，轮式单轮振动压路机1台，自卸汽车4辆、洒水车1台、平地机、刮平面1台等。 四、施工准备
1、土方路基验收:已形成路基的压实度、平整度、纵断高程、宽度、厚度、横坡、弯沉等技术指标经自检合格后报监理工程师抽查,经抽检各项指标符合规范要求。
2、级配砂砾底面基层各项试验按照试验规程已完成，附试验资料。
3、施工放样：在达到标准的路基上恢复中线，直线段每25m设一桩，曲线段每20m设一桩，并在两侧边缘外设指示桩。在两侧指示桩上用明显标记标出级配砂砾底基层的设计标高。
五、级配砂砾底面层施工工序
1．施工工艺
路槽验收—准备集料—摊铺整平—洒水碾压—质量检查—洒水养生。
2．施工方案
通过自卸汽车运输,机械摊铺，2个施工作业队交替配合装载机粗平、平地机精平、
机械压实。碾压成型的底基层采用自喷式洒水车洒水养生的方案。
3．施工方法：
1）路槽准备
在铺筑天然砂砾垫层之前，应从填筑好的路床上将所有浮土、杂物清除干净，并严格整形和压实，使其达到设计所规定的要求。
路槽上的车辙、松软部分和压实不足的地方，以及任何不符合规定要求的表面都应翻松、清除或掺添同类材料，重新进行整修，使其达到规范要求。
2）集料准备
天然砂砾面层所用砂砾在调查试验并进行试配和标准击实的基础上，确认合格后方可进料。各种材料均按指定料场用汽车运输到工地。材料设专人管理、专人验收，严把质量关。
3）摊铺、整平
摊铺时的砂砾料含水量略高于压实时的最佳含水量,以弥补施工过程中的水分损失。装载机将运至现场的砂砾料推平,用平地机粗平,人工根据设计高程和摊铺系数挂左、中、右三条线（弯道加宽超高部分挂“米”字线）进行精平,以确保表面平整，厚度均匀， 横坡标准。摊铺系数经试验后，在1.25～1.30之间，具体数值我们在施工过程中根据实际测试后确定。整形过程为：平地机粗平→人工挂线精平→振动压路机稳压→人工配合平地机修整缺陷处→检查平整度、厚度及横坡和路拱→进入碾压工序。
4）压实
摊铺整形完成后，如级配砂砾含水量较小，可进行补充洒水，使其达到最佳含水量。发现集料离析时，要及时进行处理，对过细或过粗材料，应掺入适用的材料或挖除重新填筑。
压实采用先振动后静压，碾压方向均应与中线平行，直线段由边到中，由慢到快，超高段由内向外依次进行碾压。碾压时后轮重迭1/3轮宽，且必须超过两接缝处，直至压实度不小于96%。成型后的垫层应表面平整，无明显轮迹，具有标准的横坡和路拱。
5）质量检查
对砂砾面层压实度、平整度、高程、厚度、横坡、宽度进行自检，并提交监理工程师抽检审查批准后，方可进行下道工序施工。
6）养生
养生时控制洒水量，使砂砾面层表面保持湿润，不得有积水现象。碾压结束后经自检合格报请监理工程师检查验收，验收合格，及时进行养生。
三、级配砂砾底面层施工注意事项
（1）检查密实度
密实度≧96%。采用灌砂法检查，每车道每200m检查４个点。
（2）依据铺筑路段确定的松铺系数，计算出控制摊铺标高数据，在各桩测出后挂线、摊铺、整平、碾压。
（3）摊铺
级配砂砾面基层施工采用全幅摊铺，装载机摊铺后，人工配合平地机整平。安排
专人负责摊铺厚度、平整度、横坡等指标的控制，发现问题及时反映，以免影响砂砾面层的摊铺质量。摊铺时应注意天气变化，对天气预报有雨的天气做好充分准备工作，确保摊铺有序进行，压路机要及时碾压成型。
（4）压实
摊铺后紧跟碾压工序，碾压严格遵循先慢后快、先轻后重、由低到高的原则。碾压顺序：振动稳压——振动振压——光轮压路机压实——振动复压。碾压时，根据摊铺速度及蒸发量大小，确定适宜的压实段落，避免水分散失过多及压实段落太长而造成的含水量不够或砂砾面层平整度的降低。碾压时，压路机应缓起慢行、稳停，走向要直，速度要均匀，力求避免压路机的停止位置在同一断面上，而造成该断面出现台阶现象。

Two regulations promulgated for implementation is in the party in power for a long time and the rule of law conditions, the implementation of comprehensive strictly strategic plan, implementation in accordance with the rules and discipline to manage the party, strengthen inner-party supervision of major initiatives. The two regulations supporting each other, the < code > adhere to a positive advocate, focusing on morality is of Party members and Party leading cadres can see, enough to get a high standard; < rule > around the party discipline, disciplinary ruler requirements, listed as "negative list, focusing on vertical gauge, draw the party organizations and Party members do not touch the" bottom line ". Here, the main from four square face two party rules of interpretation: the first part introduces two party Revised regulations the necessity and the revision process; the second part is the interpretation of the two fundamental principles of the revision of laws and regulations in the party; the third part introduces two party regulations modified the main changes and needs to grasp several key problems; the fourth part on how to grasp the implementation of the two regulations of the party. < code > and < Regulations > revised the necessity and revised history of the CPC Central Committee the amendment to the Chinese Communist Party members and leading cadres honest politics several guidelines > and < Chinese Communist Party discipline and Punishment Regulations > column 1 by 2015 to strengthen party laws and regulations focus. Two party regulations revision work lasted a Years, pooling the wisdom of the whole party, ideological consensus, draw historical experience, respect for the wisdom of our predecessors, which reflects the unity of inheritance and innovation; follow the correct direction, grasp the limited goals, adhere to the party's leadership, to solve the masses of the people reflect a focus on the problem. The new revision of the < code > and < rule >, reflects the party's 18 and the eighth session of the third, the spirit of the fourth plenary session, reflecting the experience of studying and implementing the General Secretary Xi Jinping series of important speech, reflects the party's eighteen years comprehensive strictly practice. (a) revised two regulations of the party need of < the ICAC guidelines > in < in 1997 Leaders as members of the Communist Party of China clean politics certain criteria (Trial) > based on revised, the promulgation and implementation of January 2010, to strengthen the construction of the contingent of leading cadres play an important role. But with the party to manage the party strictly administering the deepening, has not been able to fully meet the actual needs. Content is too complicated, "eight prohibition, 52 are not allowed to" hard to remember, and also difficult to put into practice; the second is concisely positive advocated by the lack of prohibited provisions excessive, no autonomy requirements; the third is banned terms and discipline law, both with the party discipline, disciplinary regulations repeat and Criminal law and other laws and regulations repeat; the fourth is to "clean" the theme is not prominent, not for the existing problems, and is narrow, only needle of county-level leading cadres above. < rule > is in 1997 < Chinese Communist Party disciplinary cases (Trial) > based on revision, in December 2003 the promulgation and implementation, to strengthen the construction of the party play very important role. Along with the development of the situation, which many provisions have been unable to fully meet the comprehensive strictly administering the practice needs. One is Ji law, more than half of the provisions and criminal law and other countries laws and regulations Repetition; two is the political discipline regulations is not prominent, not specific, for violation of the party constitution, damage the authority of Party Constitution of misconduct lack necessary and serious responsibility to pursue; third is the main discipline for the leading cadres, does not cover all Party members. Based on the above situation, need to < the criterion of a clean and honest administration > and < rule > the two is likely to be more relevant regulations first amendment. By revising, really put the authority of Party discipline, the seriousness in the party tree and call up the majority of Party members and cadres of the party constitution of party compasses party consciousness. (II) two party regulations revision process the Central Committee of the Communist Party of China attaches great importance to two regulations revision . Xi Jinping, general books recorded in the Fifth Plenary Session of the eighth session of the Central Commission for Discipline Inspection, on the revised regulations < > made clear instructions. According to the central deployment, the Central Commission for Discipline Inspection from 2014 under six months begin study two regulations revision. The Standing Committee of the Central Commission for Discipline Inspection 4 review revised. Comrade Wang Qishan 14 times held a special meeting to study two regulations revision, amendment clarifies the direction, major issues of principle, path and target, respectively held a forum will listen to part of the province (area) secretary of the Party committee, Secretary of the Discipline Inspection Commission, part of the central ministries and state organs Department
The first party committee is mainly responsible for people, views of experts and scholars and grassroots party organizations and Party members. Approved by the Central Committee of the Communist Party of China, on 7 September 2015, the general office of the Central Committee of the Party issued a notice to solicit the provinces (autonomous regions, municipalities) Party, the central ministries and commissions, state ministries and commissions of the Party (party), the General Political Department of the military, every 3 people organization of Party of two regulations revision opinion. Central Commission for Discipline Inspection of extensive solicitation of opinions, careful study, attracting, formed a revised sent reviewers. In October 8 and October 12, Central Committee Political Bureau Standing Committee and the Political Bureau of the Central Committee After consideration of the two regulations revised draft. On October 18, the Central Committee of the Communist Party of China formally issued two regulations. Can say, two laws amendment concentrated the wisdom of the whole party, embodies the party. Second, < code > and < Regulations > revision of the basic principles of two party regulations revision work and implement the party's eighteen, ten eight plenary, the spirit of the Fourth Plenary Session of the Eleventh Central Committee and General Secretary Xi Jinping important instructions on the revised < low political criterion > and < Regulations >, highlighting the ruling party characteristics, serious discipline, the discipline quite in front of the law, based on the current, a long-term, advance as a whole, with Bu Xiuding independent < rule > and < rule >. Main principle is: first, adhere to the party constitution to follow. The constitution about discipline and self-discipline required specific, awaken the party constitution of party compasses party consciousness, maintaining the authority of the constitution. General Secretary Xi Jinping pointed out that "no rules, no side round. Party constitution is the fundamental law, the party must follow the general rules. In early 2015 held the eighth session of the Central Commission for Discipline Inspection Fifth Plenary Session of the 16th Central Committee, Xi Jinping again pointed out that constitution is the party must follow the general rules, but also the general rules." the revision of the < code > and < rule > is Method in adhere to the regulations established for the purpose of combining rule of virtue is to adhere to the party constitution as a fundamental to follow, the constitution authority set up, wake up the party constitution and party rules the sense of discipline, the party constitution about discipline and self-discipline specific requirements. 4 second is to adhere to in accordance with the regulations governing the party and the party. The Party of rule of virtue "de", mainly refers to the party's ideals and beliefs, excellent traditional style. The revised the < code > closely linked to the "self-discipline", insisting on the positive initiative, for all members, highlight the "vital few", emphasized self-discipline, focusing on the morality, and the majority of Party members and the ideological and moral standards. The revised < > Ji method separately, Ji, Ji Yan to Method, as a "negative list", emphasizing the heteronomy, focusing on vertical gauge. Is this one high and one low, a positive reaction, the strict party discipline and practice results transformation for the integration of the whole party to observe moral and discipline requirements, for the majority of Party members and cadres provides benchmarking and ruler. Third, insist on to. In view of the problems existing in the party at the present stage, the main problems of Party members and cadres in the aspect of self-discipline and abide by the discipline to make clearly defined, especially the party's eighteen years strict political discipline and political rules, organization and discipline and to implement the central eight provisions of the spirit against the four winds and other requirements into Disciplinary provisions. Not one pace reachs the designated position, focusing on in line with reality, pragmatic and effective. After the revision of major changes, major changes in the < code > and < rule > modified and needs to grasp several key problems (a) < code > < code > adhere to according to regulations governing the party and party with morals in combination, for at the present stage, the leadership of the party members and cadres and Party members in existing main problems of self-discipline, put forward principles, requirements and specifications, showing Communists noble moral pursuit, reflected at all times and in all over the world ethics from high from low 5 common requirements. One is closely linked to the "self-discipline", removal and no direct relation to the provisions of . the second is adhere to a positive advocate, "eight prohibition" 52 are not allowed to "about the content of the" negative list moved into synchronization amendment < cases >. Three is for all the party members, will
