Application of the plant-mix cold recycling technology of foamed asphalt to pavement reconstruction project: A case study

In the study, the plant-mix cold recycling technology of foamed asphalt (PCRTFA) was applied to a reconstruction project of a highway in Hainan province, China. The mix proportions of the raw materials and related parameters of PCRTFA were analyzed firstly. Then, the pavement construction test was carried out. After that, the reconstruction project of the highway was performed. At last, the construction technology and quality control were expounded. The case study shows that the PCRTFB can achieve the purpose of reusing resources and save construction costs. This study can provide technical reference for other similar pavement reconstruction projects in Hainan province.
