Crack Monitoring of AKLEH, Kuala Lumpur

Ampang-Kuala Lumpur Elevated Highway (AKLEH) was the first elevated highway in Malaysia and completed in 1996. The 7.7km highway was built to reduce traffic jams in Jalan Ampang and make access to the city more convenient.

In spite of remedial works undertaken in 2003 to some of the piers, new cracks were observed around four years later. JTK Consult (JTK) was appointed to remediate these new cracks and prevent any future occurrence.

JTK study showed that the cracks were due to expansion from thermal load and delayed ettringite formation. Carbon fibre wrapping and waterproofing was introduced as a remedial measure to contain future expansion and prevent water ingress into the concrete.
