Types of Failures in Flexible Pavements -Causes and Repair

Some of the structural distresses which can cause failures in flexible pavements are: 1. Alligator Cracking of Flexible Pavements Alligator cracks are also called as map cracking. This is a fatigue failure caused in the asphalt concrete. A series of interconnected cracks are observed due to such distress. The tensile stress is maximum at the

Therefore, the causes of premature deterioration in relatively new buildings are different as compared to those for old buildings. Poor concrete and / or bad rebar detailing should always be checked in column beam junction as shown in figure 2. Sub-standard workmanship during construction also affects the quality of construction.

elasticity of the existing Portland cement concrete (PCC) and the k-value of all supporting layers. For asphalt concrete (AC) pavements, FWD testing is used to backcalculate the stiffness of each layer and to estimate the amount of damage in the existing asphalt. This report summarizes the testing protocols and data analysis procedures recommended.

How Does Weather Effect Asphalt Pavement? | Bituminous

Water is the biggest threat to asphalt pavements in the spring because it causes asphalt to deteriorate (very slowly). The longer asphalt is in contact with water, the more deterioration is likely to occur. This includes water puddling on top of asphalt, water flowing across asphalt pavements, water moving into the cracks of asphalt pavements
