Abstract：Cement-stabilizedmacadamwithlarge-particlesizecanefectivelyreduce temperatureshrinkageanddryshrinkage effcts and improve road service life. In this study，a 37.5mm single-particle coarse aggregate was selected for testing， and its compressivestrength，compresiveresiliencemodulus，flexuraltensilestrengthdryshrinkageandtemperatureshinkageproperties werecomparedwithconventionalwater-stablematerialspecimens，andthecrackingresistanceandmechanicalpropertiesof water-stable filled large-particle gravel were analyzed at different ages.
