Pot Holes In Road

 

Pot Holes

Causes

The most common causes for the event of pot-holes is also summed up as follows:

1) Insufficient pavement thickness to support traffic throughout freeze/thaw periods without localized failures.

2) Insufficient drainage.

3) Failures at utility trenches and castings.

4) Miscellaneous pavement defects and cracks left unmaintained and unsealed to admit wet and compromise the pavement's structural integrity.

5)Lack of bond between the bituminous emergence and therefore the base course below due to improper application of prime coat and tack coat.

6) Insufficient bitumen content at some locations on the surface course.

7)Segregation of bituminous mix throughout laying leading to the surface remaining permeable due to fewer fines or excess coarse aggregates at some locations.

8)Presence of weak spots in any of the pavement layers at some road locations at the construction stage itself.

Patching techniques of pot-holes:

One type of repair, pothole repair, most likely receives the best quantity of public attention. pothole repair procedures cover a wide range of strategies and intentions from permanent full-depth patches to temporary partial depth patches. two general repair procedures are described next.

Semi-Permanent pothole Patch

1)Remove all water and debris from the pothole.

2)Square up the pothole sides so that they are vertical and have in-tact pavement on all sides.

3)Place the repair material into the clean squared-up hole. the material ought to mound within the center and taper down so that it meets flush with the encompassing pavement edges.

4)Compact the repair material beginning within the center and working out toward the sides. Compaction may be accomplished using a vibrating plate compactor or a single-drum vibrating roller. Check the compacted repair material for a slight crown. this can be down so that subsequent traffic loading can compact it all the way down to the surrounding pavement height.
