1. wet cement stabilized gravel joint seams, refers to the mixture before the web paving aside inwardly near the edge of the seam 30 ~ 50cm is not rolling, the portion to be before it mixes with the initial setting mix paving new web dense compacted together, in order to ensure the quality of the construction joints formed by the front and rear two paving. <br>2. The binding road base construction experience, using the stepped construction, two front work surface 50 meters apart. Wet two longitudinal slits parallel processing method for the paving is formed: the first one is not close to the rolling within a range of 30 ~ 50cm side seam paving, paving and the like to the second web together compaction, then when multiple seam to be noted that rolling pressure several times, for a local surface roughness at the surface of fine sieve material for fill, such as windy and hot weather, the first part of a non-compacted plastic sheeting covering use, in order to prevent excess moisture evaporation. Wet process transverse seam construction similar longitudinal seam, is also reserved in advance paving segment 30 ~ 50cm is not rolling, rolling together the next time and the like paving. Longitudinal seams wet processing method, see "wet seaming 3 longitudinal schematic view." <br>3. The construction joints transverse process: should be butting vertical. There are two methods: one is an end portion of the day before the mix paving has been rolled into a ramp, until the next day when the paving at the top of the hill with a cutter cut flush, eradicate the mixture, re-paving the new mixture; the other is the end of the day before the paving, and grinding with the same thickness formed on top of lumber joints, all the rolling roller to be removed the next day, the construction lumber, in contact wetting sprinkler joints, then the new paving mix. After completion of paving joint, people accountable remove large particles mix at the joint, and filled with a fine mix to ensure the formation and linker, linking.

1. Cement stable gravel seam using wet seams, that is, refers to the front paving of the mixture in close to the edge of the seam to set aside 30 to 50 cm without crushing, until the part of the mixture before its initial coagulation and the rear of the new paving mixture together with the compact, to ensure the front and rear two paving formation of the construction seam quality.<br>2. Combined with the experience of the grass-roots construction of the road surface, the use of ladder construction, before and after the two working surfaces are 50 meters apart. The vertical wet seam treatment method formed by the two parallel paving is: the first one near the seam side of the 30 to 50cm range of paving without crushing, such as the second paving to one time and compaction, seam crushing should pay attention to a few times, local surface rough to sieve fine material to make up, such as wind and hot weather, The first uncrushed part is covered with plastic sheeting to prevent excessive evaporation of water. The treatment of horizontal construction wet seams is similar to the vertical seams, the pre-paving section is also reserved for 30 to 50 cm not to be crushed, and so on the next paving time and crush. The longitudinal wet seam treatment method is shown in Figure 3 longitudinal wet seam treatment schematic.<br>3. Treatment of horizontal construction seams: vertical flat connection should be used. Methods are two: first, the previous day paved mixture end has been crushed into a slope-like, until the next day paving, at the top of the slope with a cutting machine to cut, the mixture will be eliminated, re-paved new mixture; To the next day of construction will remove the square wood, at the seams sprinkled with water wetting, and then spread new mixture. After the paving joint is completed, send a person responsible for removing the large particles in the mixture at the joint, filling with fine mixture to ensure that the joint is smooth and connected.

1. Wet joint is adopted for cement stabilized macadam joint, which means that 30-50cm of the mixture paved in front of the joint edge shall not be rolled in, until this part of mixture is compacted together with the mixture newly paved in the back before its initial setting, so as to ensure the quality of construction joint formed by the two pavements.<br>2. Based on the construction experience of the pavement base, the ladder construction is adopted, and the distance between the two working surfaces is 50m. The treatment method of longitudinal wet joint formed by two parallel pavements is as follows: the first one is close to the joint within 30-50cm, no rolling is required when paving, and the second one is to be compacted when paving. When rolling the joint, pay attention to several times of rolling, and screen fine materials for patching at the rough part of the surface. In case of strong wind and hot weather, the first part not rolled shall be covered with plastic cloth To prevent excessive evaporation of water. The treatment of transverse construction wet joint is similar to that of longitudinal joint, and 30-50cm is reserved in the early paving section without rolling, and rolling shall be carried out at the next paving. See "Fig. 3 Schematic diagram of longitudinal wet joint treatment" for the treatment method of longitudinal wet joint.<br>3. Treatment of transverse construction joint: vertical flat joint shall be adopted. There are two methods: one is that the end of the mixture paved the previous day has been rolled into a slope shape, and when paving the next day, the cutting machine is used at the top of the slope to cut out the mixture and pave the new mixture again; the other is that when paving to the end of the previous day, the square wood with the same thickness as the rolling forming is used at the joint, and the roller is used to roll all the mixture, and the square wood will be removed when construction is carried out the next day Drop, wet the joint with water, and then spread new mixture. After the joint is paved, a special person shall be assigned to remove the large particles in the mixture at the joint and fill them with fine mixture to ensure the smoothness and smooth connection of the joint.<br>
