Thermal Cracking (Transverse Cracking)

ة

راﺮﺤﻟا ﻦﻋ ﺔﺠﺗﺎﻨﻟا قﻮﻘﺸﻟا

When a pavement cools quickly, it tries to contract. The internal stresses caused in this process may result in a series of cracks evenly spaced perpendicular (transverse) to the flow of traffic. There are two types of thermal cracks -- those occurring during a single falling temperature event, and those caused from damage accumulated after repeated temperature cycling. ﺺﻠﻘﺘﺗ نأ لوﺎﺤﺗ ﺎﻬﻧﺈﻓ ﺔﻋﺮﺴﺑ لﻮﺒﺠﻤﻟا ﺔﻘﺒﻃ دﺮﺒﺘﺗ ﺎﻣﺪﻨﻋ , يدﺆﺗو تﺎﻘﻘﺸﺗ ﺔﻠﺴﻠﺳ ثوﺪﺣ ﻰﻟإ ﺔﻘﻳﺮﻄﻟا ﻩﺬﻬﺑ ﺔﺒﺒﺴﺘﻤﻟا ﺔﻴﻠﺧاﺪﻟا تادﺎﻬﺟﻹا ﺮﻴﺴﻟا ةﺎﺠﺗإ ﻊﻣ ﺔﺿرﺎﻌﺘﻣ . ﺔﻳراﺮﺤﻟا قﻮﻘﺸﻟا ﻦﻣ نﺎﻋﻮﻧ ﺪﺟﻮﻳ , طﻮﺒﻬﻟا لﻼﺧ ﻦﻣ ﺮﻬﻈﻳ اﺬهو ةراﺮﺤﻟا تﺎﺟرﺪﻟ , ﺗ ﺐﺒﺴﺑ ﻢآاﺮﺘﻤﻟا رﺮﻀﻟا ﻦﻋ ﺞﺘﻨﻳ اﺬهو تارود راﺮﻜ رﺮﻜﺘﻤﻟا ةراﺮﺤﻟا طﻮﺒه .

Potholes (Chuck holes)

تاﻮﺠﻔﻟا

Is there anyone who doesn't know what a pothole is? They can be caused by a number of factors, but usually form when water gets into cracks and

destroys the underlying structure. They most often appear when the pavement is most subjected to moisture -- in the early spring.

When moisture gets to the surface of the aggregate it can break the asphalt - aggregate bond, causing the pavement to disintegrate ا ﺖﻓﺰﻟا ﻚﺳﺎﻤﺗ ﻰﻠﻋ ﺪﻋﺎﺴﻳ ﻊﺋﺎﻤﻟا ﺖﻓﺰﻟا ﻂﻴﻠﺧ ن و ءﺎﻤﻠﻟ ﺖﻓﺰﻟا ﺔﻳﺎﻤﺣ ) ءﺎﻤﻠﻟ دﺎﻀﻣ ( . ﻞﺼﺗ ﺎﻣﺪﻨﻋ و ﻄﺑار نﺎﻓ تﺎﻳﻮﺼﺤﻟا ﺢﻄﺴﻟ ﺔﺑﻮﻃﺮﻟا و ﺖﻓﺰﻟا ﺔ ﻞﻠﺤﺗ ﻲﻓ ﺔﺒﺒﺴﺘﻣ ﺮﺴﻜﺘﺗ تﺎﻳﻮﺼﺤﻟا ) ﻚﻜﻔﺗ ( ﺖﻓﺰﻟا Cause
