AC-25 Asphalt Mixture Dynamic Stability Criteria

Abstract:

With the publication of Standard test methods of bitumen and bituminous mixtures for highway engineering " in 2011, the common asphalt mixture rutting test can be carried out in accordance with the T0719-2011 in China. But in our country, the current " Technical specifications for construction of highway engineering asphalt pavement " published in 2004 describes that the nominal maximum size of more than 19mm dense-graded asphalt concrete or asphalt treated permeable base is not suitable for carrying out specimens rutting test in accordance with the size of 300mm× 300mm ×50mm, so there is no corresponding dynamic stability requirements to the commonly used AC-25 type asphalt mixture in pavement layer in China. Combined with the Dao-He expressway pavement structure design and used the T0719-2011 method of AC-25 type different thickness rutting test, the relationship between the rutting specimen thickness and the dynamic stability is established. With reference to the requirements of asphalt pavement construction specifications and pavement structure layer on high temperature stability, the 8cm thick AC-25 common asphalt mixture dynamic stability criteria is put forward. Analyzing on AC-25 with No. 50 pure asphalt mixture dynamic stability test data, the dynamic stability requirements is put forward as validation for AC-25 asphalt mixture dynamic stability criteria in Dao-He expressway.
