Abstract

Abstract The rutting and cracking of pavements has become very common problem in India. Also the quantity of plastic waste has significantly increased in the recent year due to industrialization and population growth. Improper disposal of these plastic wastes has caused various environmental problems, hence the alternative use of waste plastic in bituminous concrete for road construction has been encouraged by the community. In the present study the Indirect Tensile Strength Test has been carried out on Marshall Samples confirming to ASTM D6931-12. Three different processes (dry process, wet process and combined process) of mixing of waste plastic were used during experimentation. It was found that the indirect tensile strength (ITS) and tensile strength ratio (TSR) of sample significantly increase up to 8%, 6% and 12% for dry process, wet process and combined process respectively for LDPE and HDPE type of waste plastic.
道路工程用塑料废沥青混凝土的间接抗拉强度研究
在印度,路面车辙和开裂已经成为一个非常普遍的问题。近年来,由于工业化和人口增长,塑料垃圾的数量也显著增加。这些塑料废物的不当处置造成了各种环境问题,因此,社会鼓励将废塑料替代沥青混凝土用于道路建设。在目前的研究中,对马歇尔样品进行了间接拉伸强度试验,确认符合ASTM D6931-12。试验采用了干法、湿法和组合法三种不同的废塑料混合工艺。研究发现,LDPE和HDPE型废塑料干法、湿法和复合法处理后试样的间接抗拉强度(ITS)和抗拉强度比(TSR)分别显著提高8%、6%和12%。
