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.
