Evaluation on Performance Test of New Airport Pavement Materials Considering Emergency Airdrop Repair Requirements
摘要
Abstract
Based on specific requirements for the airfield pavement,a comprehensive performance evaluation index system was summarized and established.Three typical early-strength cement materials were selected and tested in laboratory for compressive strength,flexural strength,and initial setting time according to the theoretical mix ratio of new cement concrete.Additionally,a 28-meter test pavement section was constructed for field validation.The results show that:silicate and sulfoaluminate cements exhibit high early strength,phosphate cement demonstrates a faster growth rate in later-stage compressive strength,and sulfoaluminate cement shows a faster growth rate in later-stage flexural strength.The initial setting time of all three materials ranges from 15 to 30 minutes.Field paving results indicate that silicate cement is easy to spread and finish with fewer air bubbles,sulfoaluminate cement has higher shrinkage and micro-cracks on the surface,while phosphate cement has excessive fluidity and more pores.Finally,a comprehensive performance evaluation method is established to assess the three materials.Silicate cement has achieved the highest score,making it the optimal choice for rapid repair and airdrop needs,providing a scientific decision-support method for runway facility emergency repair under special operational conditions.关键词
