Abstract

The technology of asphalt pavement recycling in road maintenance works has developed quite rapidly. Meanwhile, the use of plastic in hot asphalt mixtures has also developed. For this reason, the mix of RAP with LDPE plastics was carried out. The study was designed using a factorial experiment with a Completely Randomized Design (CRD) consisting of two factors and three levels. The first factor is the concentration of plastic levels of 3 levels, namely: a1 = 10%; a2 = 15% and a3 = 25%. The second factor (B) is RAP with 3 levels of treatment, namely: b1 = 0% new asphalt (pure RAP); b2 = RAP + 2% new asphalt; b3 = RAP + 4% new asphalt. The results showed that the stability value increased sharply but on the one hand also increased the cavity in the mixture exceeds the required limits so further research is needed to find the right mixture composition.

再生沥青路面及废塑料在公路养护用热拌沥青中的应用进展

公路养护工程中沥青路面的回收利用技术发展很快。同时，塑料在热沥青混合料中的应用也得到了发展。为此，进行了RAP与LDPE塑料的混炼试验。本研究采用两因素三水平完全随机设计(CRD)的析因试验设计。第一个因素是3个级别的塑料浓度，即:a1 = 10%;A2 = 15% a3 = 25%第二个因子(B)为RAP, 3级处理，即:b1 = 0%新沥青(纯RAP);b2 = RAP + 2%新沥青;b3 = RAP + 4%新沥青。结果表明，稳定性值急剧增加，但同时也增加了混合物中的空腔，超过了要求的极限，因此需要进一步研究以找到合适的混合物组成。
