青岛市润邦化工建材有限公司研制的RBS速焊自愈型灌缝胶受青睐路面一条小小的裂缝,修补起来可不轻松,用行话讲就叫“灌缝”。过去路面灌缝都是把几十公斤重的沥青胶块放到修补现场熔化,再灌到裂缝中填平。别的不说,仅仅一套现场加温的设备就需要几十万元。施工时费力费时,开支费用庞大,众多的人员上路施工还会影响交通。道路养护专业人士由衷地感慨:为了一条小小的裂缝,忙煞众多人。
Qingdao Runbang Chemical Building Materials Co., Ltd. developed RBS speed welding self-healing irrigation glue favored pavement a small crack, it is not easy to patch up, with jargon called “irrigation suture.” In the past, the filling of the pavement was done by putting dozens of kilograms of asphalt glue into the repairing site to melt it and filling it into the cracks. Do not say anything else, just a set of on-site heating equipment will need several hundred thousand dollars. Construction time-consuming, costly expenses, a large number of personnel on the road construction will affect the traffic. Road maintenance professionals heartily feeling: In order to a small crack, busy with many people.
