Studying measurement of pavement concrete slabs to be applied for rural transport roads in Ha Noi

Abstract

     In fact when mention to thermal stress in Cement concrete slabs (CCS) surface road in Hanoi area, the people often based on process 22TCN 223-95 and take ΔT = 0.84 h. Some other authors use the process as: JTG D40-2002 of China, AASHTO of American, Road Note 29 of British... and which are not unified, not consistent with conditions of area Ha noi. Therefore, the authors collected data of temperature and radiation of the last 10 years (from 2003 to 2013) in Hanoi area and is based on the theory of heat transfer so as to evaluate the effects of heat stress to the proportion of cement concrete pavement slabs for rural roads in Hanoi area.
