几年来,由于大量修筑了水泥混凝土道路及航空港机场道面,道面混凝土版灌缝玛(王帝)脂材料的性能及应用问题,曾引起了有关部门的注意和研究。现根据参加现有道面混凝土版采用玛(王帝)灌缝施工的一些经验与体会,对玛(王帝)脂填缝料的性能及应用,作简要的叙述,供大家参考。在修筑水泥混凝土道面时,混凝土版的尺寸为3米×5米或为5米×5米等等。由于气温的影响,混凝土版之间不可避免地要设置许多伸缝及缩缝,以适应气温升高与降低时混凝土版伸胀与收缩的可能性。混凝土版(?)灌以玛(王帝)脂填缝料的目的,在于防止地面水沿接缝渗入基础,降低土基的承载能力;在严寒地区,还可避免基础浸水引起的冻害,造成道面的破坏;而其较普遍的意义是便于混凝土道面的维护,
In recent years, due to a large number of built cement concrete roads and Airport Airport pavement, pavement concrete version of the filling of the material properties and applications, has attracted the attention of the relevant departments and research. Now according to the existing pavement concrete version of the use of Ma (Wang Di) pouring construction experience and experience of Ma (Wang Di) fat sealant performance and application of a brief description for your reference. In the construction of cement concrete pavement, the concrete version of the size of 3 m × 5 m or 5 m × 5 m and so on. Due to the influence of air temperature, a lot of stretch and shrinkage joints are inevitably set between concrete plates to accommodate the possibility of expansion and contraction of the concrete plate when the temperature rises and falls. The purpose of filling concrete with concrete mortar is to prevent ground water from penetrating into the foundation along seams and reducing the bearing capacity of soil foundation. In cold areas, frost damage caused by foundation immersion can also be avoided, resulting in Pavement damage; and its more common meaning is to facilitate the maintenance of concrete pavement,
