Concrete block pavement performance depends on many factors. Jointing material is one of the components that affect the performance of concrete block pavement. As there are many coastal areas around the world, then marine sand may replace the river sand as jointing material. The massive availability of marine sand and the ease of transportation make this material to be selected as a replacement for river sand. This paper presents a study of laboratory research of jointing material that was made from marine sand and mixtures of marine sand and Portland cement in comparison with river sand. The pavement was tested by push-in test and pull-out test under circumstance which was wetted condition. Water seepage test and erosion test were also conducted in this study. This research used 3 mm joint width, two cement percentages (6% and 8%), and three durations of after rain time (1 day, 3 days, and 7 days). The best performing jointing material for push-in test and pull-out test was shown by mixture of marine sand and 6% of Portland cement. In the water seepage test and erosion test, the best performing jointing material was show by mixture of marine sand and 8% of Portland cement.
