Road works

Coming from a developed country and staying in a place some ten storeys high up, i won’t get to witness this just right outside my window… …

They are now mending the road just right in front of my place.

First they segmented the road using a wooden divider. A thin wooden strip that splits the cemented section from the work-in-progress section. A wire mesh is then laid on the ground, and later covered by wet concrete (Concrete is usually made of cement, water, gravel and sand).

They then pave the concrete out evenly. And when the surface of the concrete gets a little drier, they comb through the surface using a bamboo broom to create shallow grooves to increase the skid resistance. And left to dry.

It’s 5 pm here. And the guys are knocking off. Am not sure what’s next. Will update again when they continue work.

Am back, so here’s how the grooves are created. The previously inserted wooden blocks are hacked off once the concrete hardens. The grooves are necessary to allow expansion and contraction of the concrete slabs to prevent cracks due to pressure from the movement.

Groove created, allowing concrete to expand and/or contract without transferring pressure causing cracks within the concrete slabs.
