彩色沥青冷补料的养护要注意什么？

春季：要防止路面构造发作而形成冻胀，在路面表层有水痕的部位，需求在路肩路基边坡处挖排水渗沟，将冬季蓄积的雨水排到构造之外。也可在彩色沥青路面上覆撒干土，干土一方面能够吸收路面构造中的水分，另一方面还可减缓热量沿路面构造下传的速度，使路面构造中的冻水迟缓消融，并自行逐渐浸透到排水沟中，防止路面构造发作溶融性破怀。

Spring: to prevent frost heaving caused by the occurrence of pavement structure, where there are water marks on the surface of the pavement, it is necessary to dig a drainage seepage ditch at the shoulder subgrade slope to drain the rainwater accumulated in winter out of the structure. The colored asphalt pavement can also be covered with dry soil. On the one hand, the dry soil can absorb the water in the pavement structure, on the other hand, it can also slow down the transmission speed of heat along the pavement structure, slow the melting of frozen water in the pavement structure, and gradually soak into the drainage ditch by itself, so as to prevent the dissolution of pavement structure.

夏季：气温高，彩色沥青路面就十分容易老化，使路面成波浪状。这种状况下，可采取洒水降温措施。洒水普通在下午两点左右中止，水量不能太大，以湿润潮湿为宜，可多洒两遍，但不能构成路面积水及影响交通平安。

Summer: when the temperature is high, the colored asphalt pavement is very easy to age, making the pavement wavy. In this case, watering and cooling measures can be taken. Watering is usually stopped at about 2 p.m. the amount of water should not be too large. It is appropriate to be wet and wet. It can be sprinkled twice more, but it can not form Road area water and affect traffic safety.

秋季：要做好公路沿线边沟积水的引导排放工作，防止这些积水成为冬季路面构造冻结毛细水的补给水源。夏季要做好路面排水，防止彩色沥青路面构造处于湿润工作状态而惹起毁坏。

Autumn: it is necessary to guide and discharge the accumulated water in the side ditch along the highway to prevent these accumulated water from becoming the supply source of frozen capillary water in the pavement structure in winter. Pavement drainage shall be done well in summer to prevent damage caused by wet working condition of colored asphalt pavement structure.

冬季：要将纵横裂痕处打扫洁净，用液化气将缝壁加热粘性状态后，再把沥青或沥青砂浆(在低温湿润时节宜喷洒乳化沥青)，喷抹到缝中，再匀撒一层2～5mm的枯燥干净石屑或粗砂加以维护，后用轻型压路机将矿料碾压。假如是细小的裂痕，则要预先用盘式铣刀停止扩宽，再按上述办法做处置，沿裂痕涂刷少量稠度较低的沥青。

Winter: clean the vertical and horizontal cracks, heat the joint wall with liquefied gas to the viscous state, then spray asphalt or asphalt mortar (emulsified asphalt should be sprayed in the low-temperature wet season) into the joint, and then evenly sprinkle a layer of 2 ~ 5mm dry and clean stone chips or coarse sand for maintenance, and then roll the mineral aggregate with a light roller. If it is a small crack, stop widening with a disc milling cutter in advance, and then handle it according to the above method, and brush a small amount of asphalt with low consistency along the crack.
