Numerical Simulation on Reflective Cracking Behavior of Asphalt Pavement

چکیده

Cracks are one of the main problems that plague road workers. A correct understanding internal crack propagation mechanism asphalt pavement will help workers evaluate road’s working status more comprehensively and make reasonable decisions in design, construction, maintenance work. This paper established a three-dimensional layered model using software ABAQUS fracture mechanics theory extended finite element method were used to explore mechanical response base layer’s preset reflective cracks. investigated influence modulus each layer, vehicle load on principal stress, shear J-integral, two stress intensity factors (K1, K2) during predetermined process entropy was analyze above-mentioned response. The results show factor affecting cracks pavements is bottom surface layer. However, from modeling perspective, effect increasing growth obvious. Therefore, terms technical feasibility, prevention should still be achieved by controlling driving prohibiting overloading.

Investigation of Clay Balls in Asphalt Pavement

Clay ball is a pavement surface defect which refers to a clump in which clay or dirt is 8 mixed with hot asphalt mixture. Clay ball is typically caused by a combination of aggregate 9 contamination of clay or soil, high aggregate moisture, and low production temperature at the 10 asphalt plant. It usually appears a few weeks or months after paving under traffic load, after being 11 liquefied an...

Patch Distress Detection in Asphalt Pavement Images

Pavement condition assessment is an indispensable constituent in maintaining roadway infrastructure. Current practices for pavement condition assessment are labor intensive which introduce subjectivity in pavement rating and are time consuming. Automated methods rely on full 3D reconstruction of the pavement surface which introduces high equipment and computation costs. This paper presents a me...
