STUDY ON BLISTERING OF AIRPORT PAVEMENT

Ryuji ABE$B!$(B Hideto TAKEMOTO$B!$(BHiroshi KUBO and Toshihumi HIRAO

This paper investigates the cause of asphalt pavement blistering at New Chitose Airport by reproducing the blistering phenomenon in indoor tests using conditions of the site. Blistering was found to be affected by void content and pavement temperature. This paper reports on a blistering countermeasure in which type-II modified asphalt is installed as the surface course$B!$(B and on a blistering countermeasure in which the number of asphalt layers is decreased but their thickness is increased from those in conventional pavement.
