- The effects of old and new pavement concrete cohesional strength by different concrete surface processing mode, types of interface agent and cycle of freezing and thawing were studied through experiments and theoretical analysis to test the old and new pavement concrete cohesional strength under the ambient temperature and freezing and thawing environment. The experiments show that the interface agent has great influences on the concrete surface cohesional strength and cement paste has the best bonding effect. The old and new pavement concrete has poor frost resistance, and the compression and rupture strength of the cohesional surface are lowest under the cement-sand mortar interface agent mode. After chipping treatment, the frost resistance ability is better than the brushing treatment's.
