This paper reports on the test results from the fundamental research on the behavior of the construction joint of the asphalt pavement by means of the beam flexural test. Flexural test was performed at -10, -5, 0, 5, 10, 15, 20℃, at the rate of strain of 0.28×10^[-21]/sec, and the test results were analyzed by strain at rupture, flexural strength, required energy for failure, and stress relaxation modulus. Test results were summarized as follows. 1) The strain at rupture expresses more clearly the joint behavior than the flexural strength. 2) Factors controlling the joint behavior are as follows. a. Type of joint construction b. Type of binder (rheological property of binder) c. Binder content d. Composition and aggregate grading 3) A good result was obtained by kneading action from wheel tracking. This test result may be taken into consideration in the preferable construction method. 4) The preferable result may be obtained from both of construction method and properties of the material used. 5) The most important property of the material may be expressed by means of stress relaxation property.
