Abstract: The parameter of CPN,a kind of hold type rutmeter instrument,is introduced as well as the diferences between the CPN and the existing rutmeter.The applicability of CPN rutmeter used for evaluating the rut·resistance property of high grade hot mixed asphalt mixed pavement was tested and assessed through a material experiment.The calculation formula that was in accordance with the norMal rutmeter experiment was managed to get.The CPN used for the rut-resistance property evaluation is feasible through the control expe riment.

Key words: rut-resistance property, CPN rutmeter, hot mixed asphalt(HMA)
