Abstract: Crack sealing is a routine and necessary operation of paveme nt maintenance. Manual observation of road surfaces has been the most common method for evaluating road surface cracks around the world.

Performance Evaluation of Hot and Cold Pour Crack Sealing ...

Also, hot rubber asphalt may stick to vehicles’ tires due to lack of adherence to the pavement. Thus, alternative sealing materials, such as cold pour sealants, have often been the subject of research studies. This study comes as an attempt to determine the feasibility of using hot pour and cold pour sealants.

by sealing cracks which are more than 1⁄4” wide. Sealed cracks, a few feet apart. Widely spaced, well-sealed cracks. Water enters unsealed cracks softening pavement and causing secondary cracks. Open crack – 1⁄2” or more in width. Pavement ravels and erodes along open cracks causing deterioration. Tight cracks less than 1⁄4” in width.

Evaluation of Moisture Damage under Crack-Sealed Asphalt ...

Crack sealing prevents the ingress of water in the pavement structure, thus preventing the weakening of the pavement and delaying its deterioration. Earlier studies indicate that sealing pavements in areas with a high ground water table (GWT) may prevent moisture from escaping upwards through cracks in asphalt pavements, therefore, accelerating ...
