In order to study the condition and quality of asphalt concrete pavement,this paper takes the asphalt concrete pavement of a highway as the research object,and analyzes the pavement strength test and pavement condition investigation.The results show that:the detection of asphalt concrete pavement can improve the compaction and anti-skid performance of the pavement and meet the standard of driving safety;Under the action of heavy-duty traffic,stratum rock and soil characteristics,topography and air temperature,there are certain differences in the strength of asphalt pavement;The overall strength of the asphalt pavement in the right lane is lower than that on the left side,and the reason is that the vehicle load in the right lane is too large,which leads to its rapid attenuation;54.9%of the evaluated road sections were in good asphalt pavement condition,30.2%were in medium condition,and 14.9%were in poor use condition.
