Pothole season
The heavy rains the past days have taken a toll on many roads. Special mention here would be city roads such as main arterials where traffic flow is affected by the pavement conditions. Here are a couple of photos of potholes along Katipunan Avenue.
The photos also reveal that cement concrete slabs are actually under the asphalt concrete. This means asphalt concrete was used more as an overlay to protect the cement concrete slab rather than as the main structural component that will carry the traffic loads. The pavement slabs may not necessarily be compromised but the hammering action of tires/wheels as they hit the potholes will definitely lead to more damage. The water, of course, is worrisome because once they seep or penetrate the cracks and interfaces between the slabs, they may compromise the layers beneath the slab. This will weaken the foundation of the pavement and lead to more critical damage. The challenge is how to repair these potholes when we are still experiencing heavy rains. Now that’s something the DPWH needs to figure out, learn and apply rather than the usual patch up work that results in mounds of asphalt replacing the potholes.

On asphalt overlays and opportunities to rationalize pavement markings
Entire road sections along my commuting routes have had recent asphalt overlays or are being prepared for it. This is part of the national government’s regular maintenance program for roads implemented by the Department of Public Works and Highways (DPWH).
Newly asphalted pavement along the eastbound section of Ortigas Avenue Extension – can you guess how many lanes will fit here?
The previous photo was taken one week ago. This is what the section looks like after the contractor restored the pavement markings. I say restore because these are practically the same 3 lanes prior to the asphalt overlay to the rigid pavement structure.
Pavement marking delineating the traffic lanes, median and gutter
I wonder if the DPWH included bike lanes when they contacted the asphalt overlay and pavement markings for this road. There was none before and the new overlay presented a blank slate to which Class III bike lanes could at least have been provided. There is already an increasing number of bike-to-work traffic along Ortigas Ave. Ext. and the Manila East Road, which connects the large towns of Rizal and serves as one of the major arterials connecting the Province of Rizal to Metro Manila (the other being Marcos Highway).
Asphalt overlays like this provide opportunities to rationalize road space through adjustments to the pavement markings. Granted that there’s significant bus and truck traffic along this road, it is still possible to allocate or at least delineate 1.5m to 2m for cyclists. That should also help in making motorists aware of bike traffic and in the long run influence behavior towards safer travels for all road users.
