This study presents the test results on the performance and the moisture retaining ability of semi rigid pavement using the moisture retaining grouting. The two kinds of the grouting materials were used for the Laboratory tests. The method of the tests includes the compression(3 hours and 7 days) and flexural strength(7 days) varying the P lot flow values. The test results show that the variation of the P lot value has no great effects on the strength, however, the different strength was found as the different grouting materials were used. The performance of the semi rigid pavement was evaluated varying the air void ration of the base asphalt pavement. The test results show that the flexural strength of the semi rigid pavement increases with increasing the air void of the base asphalt pavement so that the flexural strength of the semi rigid asphalt pavement can be effected by the air void of the base asphalt pavement. The moisture retaining tests were conducted and compared in the field the comparisons were made with the dense grade asphalt pavement and the semi rigid asphalt pavement with and without spraying the water. The difference of the temperature of the semi rigid pavement with the spraying water has recorded $11^{circ}C$ when it compared with the dense grade asphalt pavement and $4^{circ}C$, when it compared with the semi rigid pavement without the spraying the water. It can be seen that decrease the temperature of the pavement by the moisture retaining ability from the semi rigid pavement.
