In order to identify the construction process parameters of hot rolled asphalt(such as particle size,spreading quantity,mixing temperature,paving temperature,rolling temperature and compaction work),the orthogonal test of four factors and three levels was carried out,and taking the high-temperature performance,embed bonding,anti-sliding performance and compactness as evaluation index,the influencing degree of these construction process parameters on various performance index were analyzed,and the optimal level combination of each process parame...
