Abstract:: The compatibility of mechanical properties betweencement and asphalt mortar and repair materials wasstudied by the fbur point bending method．With the help of finite element model，the eH．ect of difkrence in modulus of substrate mortar and repair mortar on the stress and strain distribution of composite sample was studied．Resultsindicated that difference in modulusof substrate monarandrepair mortardecided the loading transfer efficiency and failure mode，which mainly innuenced compatibility of mechanical properties．Accord．ing to the serVice state of CAM，fourpoint bending fatigue test wasemployed to identify the compatibility be．tweenCAMand repair mate“a1．
