Igor S. Improvement of temperature crack resistance of asphalt layers by synthetic fiber materials application

Design methods for reinforced asphalt layers considering temperature crack resistance are developed in dissertation for improvement of durability of non-rigid pavements. Analysis of conditions of work of non-rigid pavements was performed with this. Computation schemes for reinforced asphalt layers were developed and analytical dependences for temperature crack resistance estimation were found. Temperature crack resistance condition of boundary state of reinforced asphalt layers is upgraded with consideration of possible changes of asphalt layers work conditions due to fracturing. New lasting temperature characteristics of reinforced asphalt layers and new appropriateness of temperature crack propagation of non-rigid pavements are found due to experimental investigations. On the base of experimental investigations practical recommendations for temperature crack resistance improvement of asphalt layers with reinforcement are developed.
