Research on Temperature Shrinkage Deformation Properties of Cement-Stabilized Macadam

Temperature shrinkage tests were conducted for cement-stabilized macadam base course materials of 6 gradation types under the air-dry and water-saturated conditions.It is found by analyses that-10~10 ℃ is the most disadvantageous temperature range when cement-stabilized macadam base course materials are air-dry.Its temperature shrinkage strain and temperature shrinkage coefficient value are augmented sharply when the temperature declines abruptly and then recovers.The temperature shrinkage strain and temperature shrinkage coefficient values of cement-stabilized macadam base course materials under the conditions of water-saturated when temperature gets to 30~40 ℃ and-20~-10 ℃ are bigger than that under air-dry condition.
