一、问题的提出目前我国公路的黑色路面除了少量是真正的沥青混凝土之外,大多采用细粒沥青混合料作罩面,或者是沥青表面处治。因此,使用不久就出现许多坑槽、裂缝,如油石比不当,还常形成油包。对于修补坑槽和铲平油包等的养护作业,以前用人工进行时的费力和费时已不用多说,就是采用机械进行养护,仍然是省劲省时不多,其成本可能还不低,质量也不见得高。例如,由人工来扶持一台一、二十公斤重的风镐去破坏路面,是相当费劲的,而其振动和噪音大,对人身有相当伤害。在此前后,还要经过人工划线,清槽,填料等工序,最后才用小型压路机或振动压路机,夯板等进行压实。如果采用手
First, the issue raised At present, in addition to a small amount of China’s road is a real asphalt concrete, asphalt mixture used as a cover, or asphalt surface treatment. Therefore, the use of a lot of short-term pit, cracks, such as improper oil-stone, but also often form a fuel bag. For the repair pit and leveling oil package maintenance operations, the former manual laborious and time-consuming Needlessless to say, is the use of mechanical maintenance, saving is still less time saving, the cost may not yet low, Quality is not necessarily high. For example, manual lifting of one or 20 kilos of heavy-duty pick-and-hammers to destroy the road surface is laborious, and its vibration and noise are quite detrimental to the human body. Before and after this, but also underwent scribing, cleaning tank, packing and other processes, and finally only with a small roller or vibratory roller, rammer and other compaction. If using hand
